One Magnum Classic bar has 20 g of sugar; Mini Classic has 12 g, and other flavors land near 18–21 g per bar.
Shoppers ask this a lot at the freezer case: how much sugar sits in a single Magnum? The short answer depends on the stick you pick, but you can count on a clear range. This guide pulls the official label numbers into simple tables and plain advice so you can choose a bar that fits your day without guesswork.
How Much Sugar In A Magnum? By Size And Flavor
Magnum lists sugars both per portion (one bar) and per 100 g. Portion sizes change by line, so reading both lines matters. A Classic stick is 100 ml (about 75 g). Minis are smaller at 55 ml (about 44 g). Plant-based and “Double” lines use their own portion weights. Below you’ll find the sugars per bar for popular picks.
Sugar In Popular Magnum Bars (Per Bar)
| Variety | Portion Size | Sugars (g) |
|---|---|---|
| Classic | 100 ml (75 g) | 20 |
| White | 100 ml (75 g) | 18 |
| Almond | 90 ml (70 g) | 19.9 |
| Mini Classic | 55 ml (44 g) | 12 |
| Dairy Free Almond | — (72 g) | 18.9 |
| Utopia Double Cherry | 85 ml | 21 |
| Double Salted Caramel (Tub)* | Portion 100 ml | 21 |
*Tubs use spoon servings, not sticks. The figure above is per 100 ml portion.
How To Read Magnum Labels Without Guesswork
Every carton shows sugars per 100 g and per portion. The per 100 g line lets you compare flavors across sizes. The per portion line tells you what lands in your snack right now. If you switch from a full-size stick to a mini, your sugars drop because the portion shrinks. If you choose a “Double” stick with sauce and extra coating, sugars climb because there’s more sweet layer in the mix.
Per 100 g Versus Per Portion
Per 100 g numbers level the playing field. A Classic runs 27 g sugars per 100 g, while a White runs 25 g. Minis show 28 g per 100 g, yet the mini bar still brings only 12 g because the portion is small. That’s why both lines matter for a fair read.
Where Magnum Flavors Usually Land
The classic trio sets the baseline. Classic sits at 20 g sugars per stick, White sits at 18 g, and Almond lands at 19.9 g per bar. Minis sit lower at 12 g per bar. Newer lines with sauces, inclusions, or double coatings tend to sit near 21 g per stick. Plant-based Almond sits close to Classic at 18.9 g per bar.
Why The Numbers Differ Across Bars
Two levers drive sugars: portion size and recipe. Coatings and sauces add sweet weight. White chocolate uses a slightly different recipe than milk chocolate, which is why White sticks often list a touch less sugar than Classic at the same volume. Nuts add crunchy mass but not much sugar, so Almond stays near Classic.
How A Magnum Fits Into A Day
Public health guidance sets a daily cap for “free sugars” from foods and drinks. Adults in the UK are advised to keep free sugars under 30 g per day. A Classic at 20 g would use two-thirds of that cap, while a Mini Classic at 12 g would use under half. If you prefer a Double stick near 21 g, plan the rest of the day with lower-sugar picks to stay on track. You can read the NHS wording here: NHS sugar guidance.
What “Free Sugars” Means
Free sugars include sugars added to food and drink plus the sugars in honey, syrups, and juices. That’s the line used by global guidance too. The World Health Organization advises keeping free sugars under 10% of daily energy, with a strong case for under 5% for added benefit; see the full guideline: WHO free sugars advice.
Smart Swaps If You Want A Magnum
You don’t need to skip a treat to trim sugars. Small changes help:
- Pick a Mini Classic when you want the crack-and-cream experience in a smaller portion.
- Share a full-size stick and pair it with fresh fruit.
- Save “Double” flavors for days when you budget more grams.
- Keep water or unsweetened tea on the side instead of a sweet drink.
Exact Label Numbers You Can Trust
All figures come from current brand pages. Labels may vary by country pack, so check yours before you buy. If your pack lists only per 100 g, multiply that number by the bar’s weight in grams to estimate the sugars in your stick.
Sugar By Portion And Per 100 g
| Product | Sugars Per Portion (g) | Sugars Per 100 g (g) |
|---|---|---|
| Classic (100 ml) | 20 | 27 |
| White (100 ml) | 18 | 25 |
| Mini Classic (55 ml) | 12 | 28 |
| Almond (90 ml) | 19.9 | 29 |
| Dairy Free Almond (72 g) | 18.9 | 26.2 |
| Utopia Double Cherry (85 ml) | 21 | 29 |
Portion math: From Label To Real Life
Say your pack lists 27 g sugars per 100 g and your stick weighs 75 g. Multiply 27 × 0.75 and you get about 20 g sugars. If the pack lists sugars per 100 ml and gives a 100 ml portion weight of 75 g, use the grams line for the math.
Answers To Common “Can I…” Moments
Can I Fit A Magnum Into A Low-Sugar Day?
Yes. Pick a Mini Classic for 12 g. Keep sweet drinks off the menu and lean on savory meals, whole fruit, and dairy or plant milk without added sugar. That way, your treat stays within the cap.
Can I Choose A Lower-Sugar Flavor And Still Get The Crack?
White tends to sit a touch lower than Classic at the same size. Almond sits close to Classic. Plant-based Almond sits close as well. Mini formats drop sugars most because of the smaller bar.
