Donut King

Donut King: Two 100ml Bottles, One Very British Flavour Tradition

Bakery flavours occupy a strange position in UK vaping. Fruit sells in volume, menthol sells reliably, and dessert sits slightly apart as the category people either build their entire rotation around or actively avoid. Donut King plants its flag firmly in that dessert territory, and the name does not leave much room for interpretation. Our Donut King collection currently holds two products: the Donut King Bar Series 100ml and the Donut King N Shake 100ml. Both are £4.99. Both are 100ml. Both are listed at 0mg.

That is an unusually clean pair of products to write about, because almost every variable has been held constant. Same price, same volume, same nicotine level, same format. The only thing that separates them is the sub-range name, which means the choice between them is purely a flavour-direction decision rather than a value calculation. You are not weighing up whether the bigger bottle is worth the premium, or whether the higher strength justifies the cost. You are simply deciding which of two doors you want to walk through, and both cost a fiver.

What makes this worth a full guide rather than a paragraph is the 100ml shortfill format itself, and the particular demands that dessert and bakery liquids place on hardware. A 100ml bottle is a serious commitment of volume. If you buy one and dislike it, you have a lot of liquid to look at with regret. Dessert profiles are also the most divisive and the hardest on coils of any flavour family, which is a practical matter that catches out people who have only ever vaped fruit. Both of those things deserve proper explanation before you spend anything.

So this page covers what the two sub-range names actually signal, how 100ml shortfills work and what the nicotine arithmetic looks like at that volume, why bakery liquids gunk coils faster than anything else on the shelf, how to set a device up to flatter them, whether a dessert can really function as an all-day vape, and how the two bottles sit against the rest of our shortfill range. Flavour descriptions for each specific bottle live on the product pages, where they belong, because that is the information we hold per product rather than per collection.

Everything below assumes an adult reader. We sell strictly to people aged 18 or over, we age-verify every order, and that applies to nicotine-free products just as much as to nicotine ones. We also do not make health claims about vaping, and nothing here should be read as one. This is a product guide, written the way a shop assistant would talk you through two bottles on a counter.

Reading the Range: What Bar Series and N Shake Are Telling You

Brands communicate a lot through sub-range naming, and Donut King has chosen two names that carry very different signals to anyone who knows the UK market. Understanding the vocabulary is genuinely useful, because it is the main information you have before you open the bottle.

Bar Series. Over the last few years, bar has become shorthand for a specific flavour style: bold, sweetened, immediately readable, engineered to land hard on the first puff rather than reveal itself over a tank. It comes from the prefilled device world, where a liquid has to make its case instantly because the customer cannot adjust anything. When a bottled range borrows the bar name, it is telling you the profile has been tuned for that same directness. We stock a whole Bar Series collection across brands, which gives you a sense of how widely the convention is used.

N Shake. The shake reference points at the milkshake and dessert-drink family, which in flavour terms means creamy body, a rounder mouthfeel and a sweetness that sits thicker on the tongue than a bar-style fruit does. Liquids in this territory tend to be built with more emphasis on the base notes than the top notes, which changes how they perform across a tank and how they age in the bottle.

Why the distinction matters practically:

• Bright versus rounded. Bar-style profiles typically read sharper on the inhale. Creamy dessert profiles typically build across the exhale. Which you prefer depends heavily on whether you vape in short bursts or long sessions.
• Coil behaviour differs. Creamier liquids generally carry more of the heavy compounds that darken cotton and coat wire. We cover this properly further down, but expect a shake-style liquid to be harder on a coil than a bar-style one.
• Palate fatigue arrives at different speeds. Sweet, creamy liquid tends to saturate the palate faster. Many people find they can vape a bar-style profile all day but want a creamy one only in the evening.
• They layer differently in a rotation. Running two liquids that are both heavy and creamy tends to blur them together. A bar-style and a shake-style make a more sensible pair, which is convenient given that is exactly what this two-bottle range offers.

We are not going to invent tasting notes for either bottle here, because the collection data we hold is format and price rather than flavour breakdown. What we will say is that the two names describe genuinely different design intentions, and if you are buying both, you are buying variety rather than duplication. That is more than can be said for plenty of two-product ranges where the second bottle is a minor variation on the first.

If you find that dessert as a whole is not for you, the broader e-liquid category runs to 736 products and covers every other direction you might want to travel.

The 100ml Shortfill: What You Actually Receive and Why It Is Not Full

A 100ml shortfill arrives in a bottle sized larger than its contents. The usual configuration is 100ml of liquid in a 120ml bottle, leaving 20ml of deliberate headroom. That empty space is engineered so that two standard 10ml nicotine shots drop straight in and fill the bottle to the brim. It is not a packaging error and you have not been short-changed.

The reason the format exists is regulatory. UK rules limit any e-liquid containing nicotine to a maximum of 10ml per container and a maximum of 20mg of nicotine per millilitre. Liquid containing no nicotine faces no such volume cap. So the market splits the product: sell the flavoured base large and nicotine-free, sell the nicotine separately in compliant 10ml units, and let the adult customer combine them. That is why both Donut King bottles are listed at 0mg, and it is why 100ml at £4.99 is possible at all.

What this means in your hand:

• The bottle is genuinely nicotine-free as supplied. Vape it exactly as it comes and you are vaping 0mg, which is a completely legitimate use and one that our 0mg e-liquid range exists to serve.
• The headroom is functional. Do not decant into a full 100ml container and then discover there is nowhere for a shot to go.
• A 120ml bottle is a large object. It is a home bottle rather than a pocket bottle, and most people decant a smaller amount for daily carry.
• The child-resistant cap and tamper-evident seal are required by law and are worth keeping intact. Store the bottle sealed and out of reach of children and pets.

A shortfill is not a concentrate. This trips people up constantly. Flavour concentrates are sold in tiny bottles at high intensity and are meant to be mixed into a base at perhaps a tenth of the final volume. A shortfill is already a complete, finished, ready-to-vape liquid. Pour it into a tank and it works. Adding anything other than a nicotine shot, or possibly a small amount of matched base, will simply dilute a product that was designed to be used as is.

The volume decision. Buying 100ml of a flavour you have never tried is a bigger leap than buying 10ml. There is no way around that arithmetic, and it is the single biggest reason people hesitate over large shortfills. Our honest advice for anyone new to dessert liquids is to test the water in a smaller format first, then commit to the big bottle once you know the family suits you. If you already know you like bakery profiles, 100ml at £4.99 is one of the better volume propositions on the site.

Both bottles ship as standard from our UK warehouse, sourced through legitimate distribution, with same working day dispatch on orders placed before 4pm.

Nicotine at 100ml Scale: The Arithmetic Nobody Explains Properly

If you plan to add nicotine, the numbers at 100ml are different from the numbers at 50ml, and getting them wrong is the most common reason someone ends up with a bottle they cannot use. Here is the maths done slowly.

The standard result. You have 100ml of Donut King at 0mg, sitting in a 120ml bottle. You add two 10ml nicotine shots at 18mg each. Each shot carries 10 multiplied by 18, which is 180mg of nicotine, so two shots deliver 360mg. Your finished volume is 100 plus 20, which is 120ml. Divide 360 by 120 and you land on 3mg per millilitre. That is the classic sub-ohm strength and it is precisely why 100ml shortfills come with 20ml of headroom rather than 10ml.

With 20mg shots instead. Some shots are sold at 20mg, the legal maximum. Two of those add 400mg of nicotine to a 120ml total, which gives roughly 3.3mg per millilitre. The difference from 3mg is marginal and most palates will not register it, though heavier users sometimes notice a slightly firmer throat sensation.

Using only one shot. Nothing forces you to add both. One 18mg shot into 100ml gives 180mg spread across 110ml, which comes out at roughly 1.6mg per millilitre. That is a genuinely useful option for anyone who wants a trace of nicotine rather than a full 3mg, and it is a flexibility that no prefilled product can match.

Going above 3mg. This is where 100ml shortfills stop being convenient. Reaching 6mg from a 100ml base requires roughly 720mg of nicotine, which is four 18mg shots, taking you to 140ml of total volume. That will not fit in a 120ml bottle, so you need a larger empty container and the willingness to mix in stages. At that point most people conclude, correctly, that they should have bought a ready-made higher strength. Our nicotine salt collection runs to 582 products and our 20mg e-liquid range covers the high end without any mixing at all.

Mixing properly. A 120ml bottle needs more agitation than a 60ml one, simply because there is more liquid to move. Cap it, shake it hard for a full two minutes, then leave it to stand for a few hours so the foam settles. If you are impatient and vape it immediately after shaking, you will get an airy, slightly thin draw that has nothing to do with the liquid quality. Some people prefer slow inversions to avoid whipping air in at all, which takes longer but produces a cleaner result.

Handling nicotine. Nicotine shots are concentrated and should be treated with care. Keep them capped, mix over a wipeable surface, store them away from children and animals, and do not decant them into unmarked containers. It is basic sense rather than drama, but it is the part people skip once they have done it a few times.

Why Bakery and Dessert Profiles Are the Hardest Category to Get Right

Fruit liquids are relatively forgiving. Get the balance roughly correct and most people will accept the result. Dessert liquids have no such margin, and understanding why explains a great deal about how a range like Donut King is put together and why some people love the category while others bounce straight off it.

Dessert flavours are constructed, not extracted. A strawberry note can lean on a single dominant compound and read convincingly as strawberry. A doughnut is not one flavour, it is a construction: dough, sugar, frying, glaze, sometimes a filling, sometimes a spice. Every one of those layers has to be built separately and balanced against the others. Push the dough note too hard and it reads as bread. Push the sugar too hard and it becomes generic sweetness with no identity. Miss the fried element entirely and you have a plain cake flavour wearing a doughnut's name.

The vapour medium changes everything. Flavour in food arrives with texture, temperature and aroma working together. In vapour you lose texture entirely and you gain heat, which volatilises compounds in a different order than chewing does. Creamy notes in particular behave unpredictably: they can sit beautifully at one wattage and turn slightly sour or plasticky at another. This is why dessert liquids are far more sensitive to device settings than fruit liquids are, a point we return to in detail later.

Sweetness has a ceiling. Every dessert liquid faces the same tension. Too little sweetener and the profile reads as flat and savoury. Too much and it saturates the palate within a tank, coats the coil and flattens everything else in the mix. The good dessert makers work just under that ceiling. The lazy ones simply add more sweetener and let it carry the whole flavour, which tastes impressive for ten puffs and tiresome thereafter.

What all of this means for you as a buyer:

• Give a dessert liquid a full tank before judging it. First impressions in this category are unusually unreliable, and a profile that seems too much at puff one often settles.
• Judge it on a fresh coil. A dessert liquid tasted on a coil that has already run a week of something else is being judged unfairly.
• Expect it to taste different at different power levels. That is not a fault, it is the nature of the category.
• Accept that palate fatigue is real. Nobody's tongue stays neutral through eight hours of sweet, creamy vapour.

If you decide the whole family is not for you, that is a perfectly common outcome, and our fruit-led collections such as watermelon e-liquids sit at the opposite end of the spectrum.

Coil Gunk, Sweeteners and the Maintenance Tax of a Dessert Bottle

Here is the practical cost of vaping dessert liquids, and it is one that fruit vapers genuinely do not have to think about. Sweetened, creamy liquids kill coils faster than anything else you can put in a tank. Not slightly faster. Substantially faster.

The mechanism. Most sweetener used in e-liquid is sucralose. Sucralose does not vaporise cleanly at coil temperatures. Instead it caramelises and leaves a dark residue on the wire and the cotton, exactly as sugar does in a hot pan. Each puff adds another microscopic layer. That layer insulates the wire from the liquid, so the coil has to run hotter to produce the same vapour, which caramelises the next layer faster still. The process accelerates. Cream and custard notes contribute their own heavier compounds to the same coating.

What you will actually notice, in order:

1. The flavour dulls slightly. Not burnt, just less vivid than it was yesterday.
2. The vapour warms up. Same wattage, hotter draw.
3. A faint sharpness or bitterness appears at the back of the exhale.
4. A genuine burnt note arrives, at which point the coil is finished and no amount of hoping will bring it back.

How long should a coil last on a dessert liquid? Considerably less than on a clean fruit or menthol. Where a light liquid might give you a fortnight, a heavily sweetened dessert can cut that to a few days of solid use. This is not a defect in the liquid and it is not a defect in the coil. It is the physics of putting sugar on hot metal. Factor it into what the liquid actually costs you, and keep spares in the drawer from our vape coils section so a dead coil never means a day without your device.

Practical measures that genuinely help:

• Run cooler. Dropping a few watts below where you would run a fruit liquid slows caramelisation noticeably and often improves the flavour balance at the same time.
• Do not chain vape. Back-to-back puffs never let the coil cool or the cotton re-saturate fully, which concentrates residue.
• Change flavour families with the coil. A dessert liquid ghosts into whatever follows it. Fruit vaped on an ex-dessert coil tastes muddy.
• Dedicate a device. Heavy dessert users often keep one tank purely for sweet liquids and another for everything else. It is the cleanest solution by some distance.
• Do not bother trying to clean a gunked coil. Rinsing removes some residue and destroys the cotton's wicking in the process. Replace it.

None of this should put you off. It is simply the honest trade for a category of flavour that fruit cannot replicate. Knowing it in advance is the difference between an informed purchase and a disappointed one.

Can a Dessert Be an All-Day Vape? Building a Sensible Rotation

The all-day vape is one of vaping's most argued-over ideas: a single liquid you can use from morning to night without ever getting bored of it. Dessert liquids have a complicated relationship with the concept, and being realistic about it will save you money.

The case against. Sweet, creamy vapour saturates the palate. After a few hours the flavour receptors that were registering all the interesting detail have simply stopped responding to it, and you end up tasting generic sweetness rather than the profile you paid for. This is called palate fatigue and it is a physiological fact rather than a preference. Fruit liquids with a sharp or icy edge reset the palate as they go. Dessert liquids do the opposite: they build.

The case for. Plenty of people vape a dessert liquid exclusively and are perfectly happy. Two things make it work. The first is running the liquid at moderate power rather than chasing huge clouds, which keeps the intensity down. The second is drinking water, which does more to reset a palate than most people expect. If you already smoke or vape while drinking coffee or tea, you will find the interaction between the drink and the liquid matters more with dessert than with anything else.

The rotation approach, which is what most experienced vapers land on:

• Morning. Something clean and simple, often menthol or a light fruit. The palate is fresh and heavy sweetness is unwelcome.
• Daytime. A bar-style profile that stays interesting without being demanding. This is where a bar-series liquid earns its place.
• Evening. The creamier, richer bottle, used the way you would use a dessert after a meal. This is where a shake-style liquid genuinely shines.
• Reset. Every few days, a plainer liquid to stop the sweet notes blurring into background noise.

The convenient thing about a two-bottle range built on a bar profile and a shake profile is that it maps onto this pattern almost exactly. Buy both, run one in the day and one in the evening, and you have a functioning rotation for £9.98 covering 200ml of liquid. That is a genuinely efficient way to structure a dessert habit, and it is more useful than buying two bottles of the same thing.

Rotating across formats, not just flavours. Many people run a big shortfill in a sub-ohm tank at home and a small high-strength bottle in a pod device when out. Our 5 for £10 e-liquid deal is the usual home for that second half of the setup, since it puts small bottles at £2 each and makes variety cheap.

Tuning the Device: Wattage, Airflow and the Temperature of the Draw

Dessert liquids reward careful device setup more than any other category, and punish careless setup more too. If a bakery liquid tastes wrong to you, there is a decent chance the device is at fault rather than the bottle.

Start lower than you think. Take whatever wattage your coil suggests and begin at the bottom of that range rather than the middle. Creamy and doughy notes are heat sensitive. At high power the delicate parts of the profile burn off before they reach you, leaving only sweetener and a scorched edge. At moderate power the layers arrive in order and the flavour reads as intended. Climb in increments of two or three watts, taking a few puffs at each step, and stop at the point where the flavour is fullest rather than where the cloud is biggest. Those two points are almost never the same with a dessert liquid.

Airflow is a flavour control, not just a draw control. Opening airflow cools the vapour and thins the flavour. Closing it concentrates and warms. Bakery profiles generally want a slightly warmer, slightly more restricted draw than fruit does, because heat is what carries the heavier compounds. Experiment in small movements rather than jumping between fully open and fully closed.

Coil selection. Mesh coils give even heating across a wider surface, which suits complex profiles because it avoids hot spots that scorch the delicate notes. Higher resistance coils running at lower power tend to flatter dessert liquids more than very low resistance, very high power builds. Whatever you choose, prime it properly: drip liquid directly onto the exposed cotton, fill the tank, and then leave it standing for a full ten minutes before your first puff. High vegetable glycerine shortfills are thick and cotton takes time to saturate. Impatience at this step is the single most common cause of a coil dying on day one.

Device pairing in general. A 100ml high-VG shortfill belongs in a sub-ohm tank with generous wicking channels. Our vape kits range is where you will find suitable hardware. What it does not belong in is a tight, low-power mouth-to-lung pod built for thin nicotine salt liquid, where the narrow ports simply cannot wick fast enough and you will get dry hits within a handful of puffs. If a compact pod is your only device, our pod kits section pairs far better with small high-strength bottles than with a 100ml shortfill.

A note on tank hygiene. Dessert liquids leave residue in the tank as well as on the coil. Rinsing the glass and the chimney with warm water when you change coils takes two minutes and makes a real difference to how clean the next fill tastes.

Donut King Alongside the Rest of the Shelf

Two products is a small range, so it is fair to ask how they compare with the alternatives sitting nearby. Here is an honest read of the landscape, using ranges we actually stock.

Against Doozy. Our Doozy collection runs to 106 products with prices from £2.69 to £9.99, spanning nicotine salts at 10mg and 20mg, nicotine-free options and a 100ml large-format bottle, with multibuy deals attached. That is the opposite proposition to Donut King: enormous choice, multiple formats, several strengths. If you want to explore widely, Doozy gives you far more room. If you want a straightforward dessert decision between two bottles, Donut King is quicker.

Against Bar Juice. With 47 products, our Bar Juice range is built around exactly the bar-style flavour convention discussed earlier, and it does so at scale. Anyone drawn to the Bar Series name should look at that collection too, because it is the same design philosophy applied across a much larger flavour list.

Against Grannys Pie. Our Grannys Pie collection is another dessert-territory name, and like Donut King it is a compact listing. If bakery is your family, these are the shelves to walk along together.

Against Devil Vapour. The Devil Vapour collection is a single 50ml bottle at £4.99, also at 0mg. That is a directly instructive comparison on volume: same money, half the liquid. If millilitres per pound is your metric, Donut King is twice as efficient, which is the most concrete argument in its favour on the whole page.

How to think about small ranges generally. A two-product listing is not a sign of a weak brand. Plenty of good UK juice lines run deliberately tight, releasing few flavours and standing behind them, rather than flooding a shelf with twenty variations of the same idea. What a small range does mean is that if neither bottle suits your palate, there is no third option to fall back on within the brand, and you will need to look elsewhere. That is the honest limitation, and it is worth knowing before you order.

Where Donut King wins. Volume for money, a genuinely clean two-way choice with no upselling, a nicotine-free base that lets you set your own strength or none at all, and two sub-ranges that complement rather than duplicate each other. For a dessert vaper who already knows they like the category, that is a tidy proposition.

The Value Case: 200ml for £9.98 and How to Build the Order

Let us put actual numbers on it, because cost per millilitre is the only honest way to compare e-liquid across different container sizes.

One bottle. £4.99 for 100ml works out at 4.99 pence per millilitre, which rounds to almost exactly 5p per ml. That is before any nicotine is added.

Both bottles. £9.98 for 200ml, at the same 5p per ml. Two distinct flavour directions, a functioning day and evening rotation, and enough liquid to last most sub-ohm vapers several weeks.

With nicotine added. Two shots into each bottle takes you to 120ml of finished 3mg liquid per bottle, so 240ml across the pair. Whatever you pay for the shots is added on top, but even allowing a few pounds for them, you remain comfortably in single-figure pence per millilitre.

Against small bottles. Our 5 for £10 multibuy puts 10ml nicotine salt bottles at £2 each, which is 20p per millilitre. On a straight per-millilitre basis, a 100ml shortfill is roughly four times more efficient. That is a large gap, and it is the fundamental economic argument for big bottles.

The honest counterweight. You do not consume both formats at the same rate. A 20mg nicotine salt in a small pod satisfies quickly, so daily consumption is often two or three millilitres. A 3mg shortfill in a sub-ohm tank can disappear at eight or ten millilitres a day. Add the faster coil replacement that dessert liquids demand, and the weekly cost of the two approaches can end up much closer than the per-millilitre figures suggest. Anyone telling you shortfills are simply cheaper is not counting coils.

Building the order. Free UK delivery kicks in on orders over £20. Two Donut King bottles come to £9.98, which is only half way there. Even four bottles at £4.99 lands at £19.96, four pence short of the threshold, which is a genuinely annoying piece of arithmetic worth knowing in advance. The practical answer is to add something you were going to buy anyway. A pack of coils is the obvious companion given how hard dessert liquids are on them. Beyond that, our vape deals section is the sensible place to make up the difference rather than paying postage on a small basket.

A note on buying in bulk. Do not buy four bottles of a flavour you have never tried, however good the per-millilitre maths looks. Buy one, run a full tank on a fresh coil, and decide properly. E-liquid you do not enjoy is the most expensive liquid there is, regardless of what it cost.

Ordering, Age Verification and Getting the Most From Two Bottles

The closing practicalities, and a few habits that make a 100ml bottle behave itself over the weeks it will take you to finish it.

What is in the collection. Two products: the Donut King Bar Series 100ml and the Donut King N Shake 100ml, both £4.99, both 100ml, both 0mg. Detailed flavour descriptions and ingredient information live on the individual product pages, which is where per-product detail belongs.

Decant for daily use. A 120ml bottle is not something you want rattling around a jacket pocket. Move 20ml or 30ml into a smaller bottle for carrying and keep the main bottle capped, upright and in a dark cupboard. This also slows oxidation, because every opening swaps some headspace for fresh air.

Store it properly. Cool, dark and sealed. Light degrades flavour compounds and, once nicotine is added, oxidises the nicotine and darkens the liquid. Room temperature is fine; radiators, windowsills and car interiors are not. There is no benefit to refrigerating e-liquid and some risk of condensation when a cold bottle meets a warm tank.

Let a freshly shotted bottle settle. A day or two after adding nicotine, with an occasional gentle inversion, usually produces a rounder result than vaping it straight after mixing. This matters more with creamy profiles than with fruit, because there are more layers that need to settle into each other.

Delivery. UK delivery is free on orders over £20, and orders placed before 4pm on a working day are dispatched the same day. For most UK addresses that means next working day arrival.

Genuine stock. Everything we sell is 100% genuine, bought through proper UK distribution channels. In a category where non-compliant imports do circulate, that is the baseline you should expect from any retailer, not a bonus feature.

Age restriction. We sell strictly to adults aged 18 or over. Every order is age-verified, and this applies to nicotine-free liquids exactly as it does to nicotine ones. If age verification cannot be completed, we cannot fulfil the order.

If dessert turns out not to be your family, the site is large and the alternatives are one click away. Our nicotine-free e-liquid collection holds 154 products at the same 0mg level across every flavour direction, and for adults who would rather skip bottles, coils and mixing altogether, our big puff rechargeable vapes are the compliant modern replacement for the single-use disposables that are no longer sold in the UK.
