For a biscuit recipe that simply calls for dark chocolate, a plain 70% cooking chocolate is a starting point: Marks & Spencer recommends 70% dark chocolate for baking. Choose a bar expressly described as suitable for baking if you prefer that format, or consider couverture when melting, coating or decoration is central to the recipe. Higher cocoa percentages bring a more intense, less-sweet flavour, so follow any percentage the recipe specifies and check the current pack for allergens.
The useful starting point depends on whether the chocolate will go into the dough, be melted for finishing, or need to meet an eater’s allergy requirements.
If your biscuit recipe says only “dark chocolate”, compare plain products by cocoa percentage and intended use before choosing one. Marks & Spencer recommends 70% dark chocolate for baking and describes higher percentages as more intense and less sweet.
If melting and finishing matter as much as the chocolate in the biscuit, look for a product described for those tasks. Montezuma’s describes its 74% dark couverture for melting, moulding, decorating and enrobing, as well as baking.
If the biscuits are for someone with an allergy, assess the exact pack rather than relying on the word “dark” or a vegan-recipe description. Lindt says its EXCELLENCE 70% bar is made to a vegan recipe but is not suitable for people with milk allergy.
Start with the recipe’s specified cocoa percentage and the job the chocolate needs to do. Then compare the exact ingredients and allergen information on the pack.
| Priority | What to check | Your needs |
|---|---|---|
| Cocoa percentage | Follow the percentage in the recipe if one is given. Otherwise, consider plain 70% chocolate; Marks & Spencer recommends it for baking and describes higher percentages as more intense and less sweet. | I want a noticeable dark-chocolate flavour without choosing a markedly less-sweet chocolate by accident. |
| How it will be used | Check whether the product is described for baking, melting or finishing. Montezuma’s specifies melting, coating-related work and baking for its 74% couverture; Lindt describes its EXCELLENCE 70% bar as suitable for baking. | Chocolate chopped into dough is one decision; a coating or decoration is another. I want the stated use to match the recipe. |
| Ingredients | Read the full ingredient list for fillings, added flavours or pieces. Compare the exact product with the plain chocolate the recipe calls for. | If the recipe expects plain chocolate, I do not want an inclusion to change the finished biscuit’s flavour or texture. |
| Allergens | Read the current pack’s ingredients and any precautionary allergen statement. UK government guidance says regulated allergens present in prepacked food must be clearly labelled in the ingredients list. | I need to know whether this particular pack is appropriate for the person who will eat the biscuits, not just whether it is labelled dark or vegan. |
A filled or flavoured bar can add ingredients and pieces that change the biscuit compared with a recipe using plain chocolate.
When the recipe gives no further detail, compare a plain product’s ingredients and cocoa percentage first. Consider a bar with additions only if those additions suit the recipe and its intended eaters.
Marks & Spencer describes higher-cocoa dark chocolate as more intense and less sweet. That difference matters when the recipe was written around a different chocolate.
Use the recipe’s stated percentage where possible. If it specifies none, treat 70% as a starting point and choose a higher percentage when you want that flavour change.
Those descriptions do not establish whether a particular chocolate is appropriate for someone with an allergy. Lindt, for example, says its vegan-recipe EXCELLENCE 70% bar is not suitable for people with milk allergy.
Check the current physical pack’s ingredients and precautionary statements before baking for someone with an allergy.
These examples show why the exact product matters more than the brand name alone: a cooking chocolate, couverture and ordinary bar can call for different checks.
Montezuma’s describes its Organic Dark Chocolate Couverture as a 74% cocoa product for baking and finishing work.
M&S places its Dark Chocolate product in its cooking-chocolate range and describes it for cookies and other desserts.
A Tesco listing identifies Green & Black’s Organic Cooking Chocolate as a 150 g product with 70% cocoa solids.
Lindt describes its EXCELLENCE Dark 70% bar as suitable for baking and uses squares of it in a UK shortbread recipe.
Divine identifies its plain Dark Chocolate Bar as a 90 g, 70% cocoa product.
Hotel Chocolat lists a 70% Dark Chocolate Slab Selector, a slab-format option to assess against a biscuit recipe.
These options cover cooking chocolate and ordinary dark bars at 70%, 72% and 85% cocoa. For a recipe that specifies a percentage, start there; for an ordinary bar, check how you plan to use it before substituting it for cooking chocolate.

A cooking-chocolate option to consider when a biscuit recipe calls for dark chocolate without naming a percentage. The title specifies 70% cocoa and a 100 g pack; check the current pack’s ingredients and allergens before use.
No image available
A dark bar to consider if the biscuit recipe allows a cocoa percentage other than 70%. The title states 72% cocoa and 100 g; compare the recipe’s intended percentage and check the current pack before baking for someone with an allergy.
No image available
A 70% dark bar for a recipe where you have checked that an ordinary bar suits the intended use. This 90 g product is distinct from Green & Black’s Organic Cooking Chocolate; check the exact pack’s ingredients and allergen statement.

Consider this 85% cocoa, 100 g bar when the recipe specifies higher-cocoa chocolate or you want to assess a more intense, less-sweet flavour. Check that this exact 85% variant suits the baking task; Lindt’s stated shortbread use concerns its different EXCELLENCE 70% bar.
No image available
A 90 g bar for a recipe calling for 85% cocoa, or for a deliberate move towards a more intense, less-sweet chocolate flavour. Confirm that this exact bar suits the intended baking use, and read its current allergen statement.
Plain 70% dark chocolate is a starting point: Marks & Spencer recommends 70% for baking. If the recipe gives a percentage, follow it; choose a higher one when you want the more intense, less-sweet flavour Marks & Spencer describes.
Yes, if the particular bar suits the recipe’s use. Lindt describes its EXCELLENCE Dark 70% bar as suitable for baking and cooking, and its UK shortbread recipe uses squares of that bar; do not assume the same instructions apply to every dark bar or variant.
Consider couverture when melting, coating or decoration is an important part of the bake. Montezuma’s describes its 74% dark couverture for melting, moulding, decorating, enrobing and baking; for chocolate simply chopped into dough, compare the amount and format with what your recipe needs.
Not necessarily. Lindt says its vegan-recipe EXCELLENCE 70% bar is not suitable for people with milk allergy. Check the exact current pack’s ingredients and precautionary allergen statements before serving the biscuits.
Check the cocoa percentage, ingredients, allergens, any precautionary statement and the pack weight against the recipe. For allergy decisions, use the current pack rather than assuming that another variant or an earlier product listing has the same information.
