For a personal mid-morning snack, Tesco Dark Chocolate Digestives 300 g is the clearest choice when a stated cocoa threshold matters: Tesco says its chocolate contains at least 48% cocoa solids, not that the whole biscuit does. McVitie’s lists 83 kcal and 4.4 g sugars per biscuit, compared with Tesco’s 85 kcal and 4.2 g sugars per 17 g biscuit; M&S states that chocolate makes up 32% of its recipe, which is a different measure from cocoa solids. For food provided in state-funded schools in England, Department for Education guidance restricts chocolate-coated products throughout the school day, so choose a different snack category.
Tesco states a minimum of 48% cocoa solids in the chocolate on its Dark Chocolate Digestives. McVitie’s 30% dark chocolate and M&S’s 32% chocolate describe how much of each recipe is chocolate; those figures do not give the chocolate’s cocoa-solids content.
Tesco lists 85 kcal, 4.2 g sugars and 2.1 g saturates per 17 g biscuit. McVitie’s lists 83 kcal, 4.4 g sugars and 2.1 g saturates per biscuit. Check the portion shown on the pack rather than treating per-100-g figures as one-biscuit values.
For food provided in state-funded schools in England, the Department for Education’s school food standards practical guide restricts chocolate-coated products across the school day. School-food requirements differ among the UK nations, so check the rules for the school’s location and setting.
Start with what the chocolate percentage actually measures, then compare the portion you would eat and the current pack label.
| Priority | What to check | Your needs |
|---|---|---|
| Cocoa declaration | Look for a cocoa-solids minimum and check whether it applies to the chocolate or the whole biscuit. Tesco states at least 48% for its chocolate; recipe chocolate percentages are a different measure. | If I want a documented cocoa figure, a product described only as dark chocolate does not answer that question. |
| One-biscuit portion | Compare values for the same eating unit. Tesco lists 85 kcal, 4.2 g sugars and 2.1 g saturates per 17 g biscuit; McVitie’s lists 83 kcal, 4.4 g sugars and 2.1 g saturates per biscuit. | For one mid-morning biscuit, I want the portion values rather than a comparison based only on 100 g of each product. |
| Allergens | Read the current physical pack. The product information lists wheat, milk and soya for McVitie’s; wheat and soya, with a may-contain-milk statement, for Tesco; and wheat, milk, soya and barley for M&S. | If I need to avoid an ingredient, I need the declaration for the exact pack I am buying. |
| School setting | Identify the UK nation and whether the snack is provided by a school. The Department for Education’s school food standards practical guide restricts chocolate-coated products across the school day in state-funded schools in England. | For school catering in England, I need another snack category; I cannot assume the same rule applies throughout the UK. |
A percentage of chocolate in a biscuit recipe is not the cocoa-solids percentage of that chocolate. Tesco’s stated 48% minimum applies to its chocolate component.
If cocoa content drives your choice, look for a cocoa-solids declaration and check what part of the product it describes.
M&S provides nutrition per 100 g, while Tesco and McVitie’s also give one-biscuit values. A per-biscuit figure for M&S cannot be calculated without a confirmed biscuit weight.
Use the pack’s serving information when comparing the portion you expect to eat.
The Department for Education’s restriction on chocolate-coated products concerns food provided in state-funded schools in England. Wales, Scotland and Northern Ireland have separate school-food frameworks.
Before choosing a snack for school provision, check the rules for that nation and setting. For state-funded school food in England, choose a different category.

For a one-biscuit mid-morning portion, check this twin pack’s label rather than applying values from another pack. Joybuy’s product description claims 50% cocoa solids, while McVitie’s product page does not specify a cocoa-solids percentage; check the physical pack before relying on that figure. The product details list wheat, milk and soya, so check the current pack if you need to avoid any of them.
No. Tesco states that the chocolate in its Dark Chocolate Digestives contains at least 48% cocoa solids. McVitie’s states 30% dark chocolate and M&S states 32% chocolate in their respective recipes; those figures measure chocolate content, not cocoa solids.
Tesco lists 85 kcal, 4.2 g sugars and 2.1 g saturates per 17 g biscuit. McVitie’s lists 83 kcal, 4.4 g sugars and 2.1 g saturates per biscuit. M&S gives values per 100 g, so its one-biscuit values cannot be compared without a confirmed biscuit weight.
For food provided in state-funded schools in England, the Department for Education’s school food standards practical guide restricts chocolate-coated products throughout the school day. This is not a general rule about personally packed snacks, and school-food frameworks differ in Wales, Scotland and Northern Ireland.
Check the physical pack for the exact biscuit you are buying. The product information lists wheat, milk and soya for McVitie’s; wheat and soya, with a may-contain-milk statement, for Tesco; and wheat, milk, soya and barley for M&S. Ingredients and allergen declarations can change.
