If a declared cocoa percentage matters to you, compare the chocolate coatings: the checked Tesco dark chocolate digestives state 48% minimum cocoa solids in the chocolate, while the checked Sainsbury’s pack states 35% minimum. For a breakfast you can take with you, check the portion, current allergy information and storage instructions too; a dark chocolate digestive alone should not be assumed to make a balanced breakfast.
If you need something ready to take out, a biscuit is easy to portion from a pack. Check how many you are taking and consider what else you will eat: the NHS Eatwell Guide describes dietary balance across a day or week, not one biscuit at a time.
If the cocoa content of the coating drives your choice, look for a cocoa-solids figure for the chocolate itself. The percentage of the whole biscuit made up of chocolate answers a different question.
Dark chocolate does not tell you whether a biscuit contains milk, wheat or soya, or carries a precautionary allergy statement. Read the current physical pack before eating, particularly if you ordered from an online listing.
Start with the coating if cocoa content matters, then compare a biscuit-sized portion and the practical details of taking some from an opened pack.
| Priority | What to check | Your needs |
|---|---|---|
| Cocoa declaration | Find the minimum cocoa-solids percentage for the coating, not the percentage of the biscuit that is chocolate. Tesco Groceries states 48% for the chocolate on its checked 300 g pack; Sainsbury’s states 35% for its checked 300 g pack. | I want a stated cocoa content so I can compare the chocolate coatings on the same basis. |
| Portion and nutrition | Check the serving size and nutrition per biscuit. Tesco Groceries lists 85 kcal and 4.2 g sugars for one 17 g biscuit; Sainsbury’s lists 79 kcal and 3.5 g sugars per biscuit. For other pack sizes, compare per 100 g figures on the same basis. | If I am eating a biscuit on the way out, I want to know what my portion contributes and decide what else to have for breakfast. |
| Ingredients and allergens | Read the current pack’s ingredients and allergy advice. Tesco Groceries says its checked pack may contain milk; Sainsbury’s says its checked pack is not suitable for customers with an oat allergy due to manufacturing methods. | I need to check the exact pack I will eat, rather than rely on the word ‘dark’ or an earlier online description. |
| Storage after opening | Check how to store the remainder. The checked Tesco, Sainsbury’s and M&S listings call for an airtight container; ASDA says to consume its checked 300 g pack within seven days of opening. | When I take a few biscuits out, I want to know how to keep the rest according to that pack’s instructions. |
McVitie’s and ASDA list dark chocolate as 30% of their checked biscuits. That does not say the chocolate contains 30% cocoa solids, so it cannot be compared directly with Tesco’s or Sainsbury’s coating declarations.
Look for a separate cocoa-solids statement for the chocolate on the exact pack you are considering.
Dark-coated digestives still list sugars, and biscuit sizes can differ. A cocoa declaration does not tell you what a breakfast-sized portion contributes.
Read the per-biscuit serving information and, when comparing different sizes, the per 100 g declaration. Consider the rest of the breakfast as well; the NHS Eatwell Guide frames balance across the day or week.
Allergy wording differs between the checked products, including whether milk is listed as an ingredient or a precautionary statement.
Check the ingredients and allergy advice on the physical pack you receive before eating it.
These details describe the specified dark chocolate digestive listings, not every product made by each brand.
The checked Tesco Dark Chocolate Digestives 300 g pack gives a cocoa-solids declaration for its coating and nutrition per biscuit.
The checked Sainsbury’s Dark Chocolate Digestives 300 g pack also declares cocoa solids in its coating.
The checked ASDA Dark Chocolate Digestives 300 g pack provides per-biscuit nutrition and an after-opening instruction.
McVitie’s lists a dark chocolate digestive with nutrition information per biscuit.
M&S describes its checked dark chocolate digestives as containing demerara sugar for added crunch.
These McVitie’s dark chocolate digestive packs are options to consider if you want biscuits to take with you. Check the exact pack’s cocoa declaration and nutrition if either detail determines your choice.

The twin-pack format may suit you if you want to take biscuits on more than one morning. Check the nutrition for the portion you take and read the current pack’s wheat, milk and soya allergy information before eating.

This 400 g pack is another dark chocolate digestive option if a particular cocoa-solids declaration is not essential to your choice. Check the pack for a coating cocoa percentage if it matters to you, and read its nutrition and wheat, milk and soya allergy information before eating.
No. On the checked McVitie’s and ASDA products, 30% describes the proportion of the biscuit that is dark chocolate. For cocoa content in the coating, look for a separate cocoa-solids declaration: Tesco Groceries states 48% minimum for its checked chocolate coating, and Sainsbury’s states 35% minimum for its checked coating.
Yes, the checked products are ready-to-eat biscuits. If you take some from an opened pack, follow that pack’s storage instructions; ASDA specifies consuming its checked 300 g pack within seven days of opening.
Do not assume that a dark chocolate digestive alone makes a balanced breakfast. The NHS Eatwell Guide describes a balance of different foods across a day or week, while NHS guidance on sugar identifies biscuits and chocolate among foods containing free sugars.
Read the ingredients and allergy statements on the current physical pack before eating. The checked products differ in their milk and precautionary wording, and Sainsbury’s says its checked digestives are not suitable for customers with an oat allergy due to manufacturing methods.
No. GOV.UK describes the UK colour-coded front-of-pack nutrition scheme as voluntary. Use the nutrition information available on the current pack when comparing biscuits, keeping the per-biscuit and per 100 g figures on their respective bases.
