If a declared cocoa-solids minimum matters to your Christmas bake, Tesco Groceries lists at least 48% cocoa solids in the chocolate on its dark digestives, while Sainsbury's lists at least 35% in its chocolate. Those figures describe the coatings, not the cocoa content of the whole biscuits or how the finished bake will taste. For a base or topping, also check how much chocolate the biscuits contain and read the current pack for allergens before using them.
If crushed biscuits will be noticeable in a cheesecake base, trifle topping or decoration, the cocoa-solids declaration gives you a more specific starting point than the word “dark” alone. It does not predict the flavour of the finished recipe.
When you need a set weight of crumbs, compare pack weights and the amount of chocolate in the biscuits. A coated digestive contributes more than biscuit crumbs to the mixture, so it is worth trying the chosen product in a small batch.
Check the pack you will use for ingredients, allergens and “may contain” statements. The reviewed products differ in their declarations for wheat, milk, soya and other cereals; a familiar brand name is not a substitute for the product label.
Start with the role the biscuits play in your bake, then compare the coating and the current label of each product you are considering.
| Priority | What to check | Your needs |
|---|---|---|
| Declared cocoa level | Look for a cocoa-solids minimum for the chocolate coating. Tesco Groceries lists 48% minimum for its chocolate; Sainsbury's lists 35% minimum for its chocolate. Neither figure measures the whole biscuit. | I want a stated cocoa threshold when the biscuit will be a noticeable part of the bake, rather than choosing solely by the word “dark”. |
| Recipe balance | Read the chocolate proportion and nutrition information per 100g on the product you buy. The reviewed listings give chocolate proportions from 27% to 32%, but those figures alone do not establish which finished recipe will taste sweeter. | My recipe already contains chocolate, butter or sugar, so I want to try the coated biscuits before changing the amounts of other ingredients. |
| Allergens | Check the current ingredients and precautionary statements on the pack, including references to milk, soya, wheat and other cereals. Sainsbury's also warns that its product is not suitable for customers with an oat allergy because of manufacturing methods. | If I am baking for guests with dietary restrictions, I need to check the exact pack I will use before making or serving the bake. |
| Pack quantity | Match the stated pack weight to the amount of biscuits the recipe requires. A twin pack of 2 x 266g and a 400g pack are different quantities even when both are dark chocolate digestives. | I want enough biscuits for the base and any topping without treating different pack sizes as interchangeable. |
Among the reviewed labels, Tesco Groceries declares at least 48% cocoa solids in the chocolate and Sainsbury's declares at least 35%. The other reviewed dark-coated products do not have a directly comparable minimum in their accessed listings.
If that declaration is central to your choice, check the current pack for it. Otherwise, try a small batch rather than assuming the label wording predicts the finished flavour.
A dark chocolate digestive adds a coating as well as crumbs. The reviewed product listings state chocolate proportions between 27% and 32%, so a base made with coated biscuits will not have the same ingredient composition as one made with plain digestives.
Test the specific recipe before adjusting its added chocolate, butter or sugar; the chocolate proportion alone does not tell you how much to change.
Allergen declarations vary by product. Asda lists milk, soya and wheat and warns that its biscuits may contain rye, barley and oats; Sainsbury's gives a separate manufacturing-related oat warning.
Read the ingredients and precautionary statements on the pack in hand before baking for someone with a dietary restriction.
These are references to the particular biscuit listings described below, not claims about every product made by each brand.

Its 300g dark chocolate digestives provide another stated cocoa-solids minimum for the coating.
Its 300g dark chocolate digestives give bakers a stated chocolate proportion to consider for a coated-biscuit recipe.
The reviewed 266g dark chocolate digestive listing is a branded coated-biscuit reference; its details should not be assumed to apply to other pack sizes.
Its dark chocolate digestives are an option to consider when the coated biscuits will be used as a topping or decoration.
The referenced Crawford's product is a plain 400g digestive, relevant if a recipe calls for uncoated biscuit crumbs instead.
These McVitie's dark chocolate digestive packs are options for recipes using coated biscuits. Choose the pack quantity that fits your bake, and check the current pack if a particular cocoa-solids declaration or allergen statement matters.

The twin pack gives you two 266g packs when a bake calls for coated digestive biscuits. Check the pack for wheat, milk and soya before sharing, and confirm its chocolate declaration if a particular cocoa-solids minimum matters to your recipe.

This 400g pack is another quantity to consider for a recipe using dark chocolate digestives. If the coating's cocoa-solids minimum is important, check it on the current pack; also read its wheat, milk and soya information before use.
Tesco Dark Chocolate Digestives has the higher stated minimum in the reviewed listings: Tesco Groceries specifies at least 48% cocoa solids in its dark chocolate, compared with at least 35% in the chocolate of Sainsbury's Dark Chocolate Digestives. This compares coating declarations, not the cocoa content or taste of the whole biscuits.
No. The reviewed McVitie's, Asda, Sainsbury's and M&S products list milk or milk-derived ingredients, while the Tesco listing says its product may contain milk. For a vegan bake, check the current pack and choose a product explicitly labelled as suitable for that requirement.
Read the ingredients and precautionary allergen statements on the exact pack before using it. GOV.UK's guidance for prepacked food says the label must include a full ingredients list with allergenic ingredients emphasised; product-specific warnings, such as Sainsbury's oat-allergy warning, still need separate attention.
They can be tried in a biscuit base, but they also add a chocolate coating to a recipe written for plain crumbs. Make a small batch with the product you intend to use before deciding whether to adjust other ingredients; the stated chocolate proportion cannot determine that adjustment on its own.
