Choose dark-chocolate shortbread by checking both the chocolate used and how much of the biscuit it makes up: cocoa solids describe the chocolate, while a chunk or chip percentage describes its share of the biscuit. M&S and Sainsbury’s list dark chocolate with at least 39% cocoa solids in their respective shortbreads; neither figure establishes a 70%-cocoa biscuit. If 70% cocoa is essential, plain shortbread served with separately labelled 70% chocolate gives you a stated cocoa strength without relying on the word ‘dark’.
If you want dark-chocolate pieces in your shortbread, check whether the ingredients also include milk or white chocolate pieces. A dark-chocolate chunk percentage tells you how much is included, not how strong the chocolate tastes.
If a stated cocoa percentage matters, look for the cocoa-solids declaration for the chocolate itself. The M&S and Sainsbury’s shortbreads described here state 39% minimum; a separately labelled 70% chocolate bar is a different choice.
Check the ingredients and precautionary warnings on the pack you will serve. The M&S and Sainsbury’s dark-chocolate shortbreads include butter, and M&S warns that its Chocolate Chunk Rounds are not suitable for people with a nut allergy.
Start with the chocolate declaration, then choose the biscuit format that suits the tea break and check the current pack before serving.
| Priority | What to check | Your needs |
|---|---|---|
| Cocoa strength | Read the cocoa-solids percentage for the chocolate separately from the percentage of chunks or chips. M&S lists 19% dark chunks with 39% minimum cocoa solids; Sainsbury’s Double Chocolate Shortbread lists 15% dark chips with the same stated minimum. | I want to know how dark the chocolate itself is, rather than mistaking the amount of chocolate in the biscuit for its cocoa strength. If 70% is essential, I can choose chocolate separately labelled 70% to serve alongside plain shortbread. |
| Chocolate types | Check whether the named pieces are dark only or a mixture. Waitrose lists 15% milk and 7% dark chocolate chunks in its four-pack; Sainsbury’s bakery four-pack lists 15% milk and 10% dark chunks. | A mixture of milk and dark pieces is fine for my tea break, or I would rather choose shortbread whose listed chocolate pieces are dark. |
| Biscuit format | Compare the number and size of biscuits, not just the pack name. Walker’s lists nine biscuits in its 175 g Chocolate Chip Shortbread Box, while Waitrose sells four bakery shortbreads and lists 356 kcal per biscuit. | For several tea breaks, I may prefer a box of smaller biscuits; for a shared plate, four larger biscuits may suit the occasion. I’ll compare the serving information on the exact packs. |
| Allergens | Read the current ingredients and precautionary statements, including information about wheat, milk, soya or nuts where relevant. GOV.UK says ingredients on food labels are listed by weight and allergens must be highlighted. | Someone I’m serving has an allergy, so I need to check the pack in hand rather than assume that ‘dark chocolate’ means the whole shortbread is free from milk. |
M&S lists 19% dark chocolate chunks in its Chocolate Chunk Rounds, but states that the chocolate in those chunks has at least 39% cocoa solids. Neither number describes a 70%-cocoa biscuit.
Read the inclusion and cocoa-solids declarations separately. If you need chocolate labelled 70% cocoa, check a separate chocolate product rather than inferring it from ‘dark’.

Check the types and percentages of chocolate in the exact shortbread before choosing it for a dark-chocolate preference.
Ingredient and precautionary information matters for the individual pack being served. The dark-chocolate shortbreads described here can contain milk through their butter even when their chocolate pieces are labelled dark.
