McVitie's Sugar Free Dark Biscuit is sweetened with maltitol, a sugar alcohol used instead of sugar. Maltitol can still contribute carbohydrates and may affect blood glucose, so “sugar free” does not mean carbohydrate free.
Yes, it is sold as sugar-free, but that does not mean it contains no carbohydrates. The biscuit gets carbohydrates from its flour, while its sweet taste comes from a sweetener rather than ordinary sugar.
People with diabetes can include it only with attention to portion size and their own glucose response. Although it is sugar-free, the flour and maltitol can still affect blood glucose; the label claim does not make it a free-choice snack.
Yes, eating a large amount may cause gas, bloating or diarrhoea in some people because it contains maltitol. If sugar alcohols have upset your stomach before, try a small amount or choose a different biscuit.
It tastes less like a conventional sugar-sweetened biscuit: maltitol gives a different sweetness, and the dark coating adds a cocoa-forward, less sweet finish. If you expect the taste of a regular McVitie's Digestive, the difference may be noticeable.
Yes, you can crush McVitie's Sugar Free Dark Biscuit for a cheesecake base. Its dark coating adds a cocoa flavour, so it works particularly well with chocolate or coffee fillings; allow for the sweetener’s distinct taste when balancing the filling.
Store McVitie's Sugar Free Dark Biscuit in an airtight container in a cool, dry place after opening. Moisture softens the biscuit, while heat can melt or soften its dark coating.
Yes, it has a dark chocolate-style coating over the biscuit. The cocoa taste makes it more bitter than a milk-chocolate-coated biscuit, but the “dark” description does not mean the product is unsweetened.
It can be an option when you want a biscuit with less sugar, but it is still a sweet packaged snack with carbohydrates and fat. Maltitol also means it may not suit everyone’s digestion or glucose response.
It is better treated as an occasional snack: McVitie's Sugar Free Dark Biscuit is an ultra-processed packaged product. “Sugar free” describes its sugar content, not its overall nutritional quality, so vary your everyday snacks.

McVitie's sugar-free dark biscuit is a packaged biscuit coated in dark chocolate and presented as sugar-free. Its cocoa-forward coating contrasts with the crisp, relatively plain biscuit underneath, making it a small sweet-tasting snack rather than a soft or cake-like treat.
It works well with tea or coffee, whether served as an everyday snack or alongside a simple afternoon break. The sugar-free label does not mean it is low in energy: it provides 485 kcal per 100 g. Two medium biscuits are about 30 g, a useful portion reference if you want to keep track of how much you serve. Pair it with an unsweetened drink for a less sweet-tasting snack.
Low
How many vitamins, minerals and how much fiber this food carries per calorie. A high score means a lot of nutrition for few calories.
Medium
An EatBetter score computed from fiber, protein and calorie density. A high score means staying full longer on the same calories.
Both scores are calculated per 100 g and do not change with the selected portion. The satiety score is EatBetter's own calculation, not a clinical measure.
