Who is each type for?

Home bakers following a chocolate-cake recipe

If the recipe simply specifies dark chocolate, a plain 70% cooking bar gives you a sweetened option explicitly intended for baking. Lindt lists cakes among the uses for its 70% COOKING bar, while M&S positions its 70% dark chocolate for cakes and desserts.

Frequent bakers making coatings or decorations

Look for chocolate whose stated uses match the task. Montezuma's describes its 74% couverture for melting, moulding, decorating, enrobing and baking; check the pack quantity against how often you will use it.

Bakers adjusting sweetness or checking ingredients

Montezuma's 100% cocoa Absolute Black has no added sugar, so it belongs in a recipe where you can control sweetness separately. If an eater has an allergy, assess the current ingredient and allergen statements independently of any vegan claim.

What should you check before buying?

Start with the recipe's sweetness and intended use, then check pack size and allergen information for the people who will eat the cake.

PriorityWhat to checkYour needs
Cocoa and sweetness Check the stated cocoa percentage and whether sugar is an ingredient. Montezuma's says its 100% cocoa Absolute Black has no added sugar; Lindt offers a 70% cooking bar. I want a pronounced cocoa flavour, but my recipe assumes sweetened dark chocolate. If I choose 100% cocoa instead, I need a way to adjust the recipe's sweetness.
Intended use Look for stated baking uses rather than relying on the cocoa percentage alone. Lindt names cakes and brownies for its COOKING bar; Montezuma's names melting and decorating for its couverture. For a straightforward sponge or brownie, I want chocolate specified for baking. For a coating or decoration, I need the product description to cover that task.
Pack format Compare the recipe quantity with the pack size. Lindt lists a 200 g COOKING bar, while the M&S dark cooking chocolate is a 100 g bar. A smaller bar may cover my occasional bake; a larger format makes sense only if I plan to use the remaining chocolate.
Allergens Read the current pack's ingredients, allergen declaration and any “may contain” wording. The Food Standards Agency explains that precautionary allergen labelling communicates possible unintended allergen presence. If I'm baking for someone with an allergy, I need the information for the exact product I'm using. A vegan recipe claim does not settle whether milk cross-contact is a concern.

What can go wrong in a cake recipe?

  • Swapping 100% cocoa for a sweetened 70% bar without changing the recipe

    Montezuma's Absolute Black contains no added sugar. A cake made with it in place of sweetened chocolate can taste less sweet and more bitter than intended.

    Use it when the recipe allows you to adjust sweetness; otherwise, choose a sweetened cooking chocolate that fits the recipe.

  • Assuming “vegan” means suitable for a milk allergy

    A vegan recipe claim does not rule out a milk cross-contact warning. Lindt says its 70% COOKING bar is made to a vegan recipe but is not suitable for people with a milk allergy.

    Check the physical pack's ingredients and allergen statements each time you bake for someone with an allergy.

  • Choosing added flavours for a recipe that calls for plain chocolate

    Fruit, spice or other additions change what goes into the batter or frosting, as well as the chocolate flavour the recipe calls for.

    Pick a plain bar unless those additions are an intentional part of the bake.

  • Buying a large couverture pack for one cake

    A pack intended for repeated baking leaves you with chocolate to store and use after a single recipe.

    Compare the recipe quantity with the pack size before choosing couverture over a smaller cooking bar.

Cake-baking questions

What cocoa percentage should I choose for a chocolate cake?

A plain 70% cooking chocolate is a starting point when the recipe simply calls for dark chocolate: Lindt identifies cakes as a use for its 70% COOKING bar, and M&S lists a 70% dark cooking chocolate. Check the recipe before choosing a less sweet 100% cocoa product.

Can I substitute 100% cocoa chocolate for a 70% bar?

Not without considering the recipe's sweetness. Montezuma's says its 100% cocoa Absolute Black contains no added sugar, so use it where you can adjust sweetness rather than treating it as a like-for-like swap for sweetened chocolate.

Is vegan dark chocolate suitable for someone with a milk allergy?

Not automatically. Lindt says its 70% COOKING bar is made to a vegan recipe but is not suitable for people with a milk allergy. Check the current pack's allergen declaration and precautionary statements for the exact chocolate you plan to use.
