When a cake recipe calls for melted dark chocolate, start with an unfilled bar and follow any cocoa percentage the recipe specifies. A 70% cooking bar is a practical option for recipes that simply call for dark chocolate; an ordinary plain dark bar may also suit a recipe that permits it, while wafer, caramel and flavoured pieces will change the result.
If the recipe calls for chopped or melted dark chocolate, an unfilled bar keeps wafer and other centres out of the mixture. Lindt presents its COOKING 70% bar for cakes and brownies, while Waitrose describes Menier’s 70% dark chocolate as suitable for desserts and cakes.
The Vanilla Valley’s baking guidance describes dark chocolate as having a higher proportion of cocoa solids and less sugar than milk chocolate. Check the recipe before switching from milk chocolate to a dark bar, as the finished cake can taste different.
Check the current pack’s ingredients and allergen statement before using a bar. Milk, wheat, peanuts and egg appear in some branded chocolate bars, and a vegan-recipe description does not by itself establish suitability for a milk allergy.
Start with the chocolate type in the recipe, then compare cocoa percentage, added ingredients and the current pack’s allergen information.
| Priority | What to check | Your needs |
|---|---|---|
| Cocoa and sweetness | Match the recipe’s specified chocolate type and cocoa percentage where given. Compare a stated 70% or 85% bar with what the recipe calls for rather than assuming they are interchangeable. | I want a pronounced cocoa flavour, but I do not want to change the sweetness of a recipe developed for milk chocolate without considering the effect. |
| Baking use | Look for an unfilled bar presented for cooking, cakes or desserts when chocolate is a main ingredient. Lindt describes its COOKING 70% bar for cakes and brownies; Waitrose labels Menier’s 70% bar for desserts and cakes. | My recipe needs chopped or melted dark chocolate in the cake, rather than pieces added mainly for texture. |
| Added ingredients | Read the ingredients for wafer, caramel, nuts, fruit or meringue pieces. KitKat’s dark wafer bar and Galaxy’s raspberry-meringue dark chocolate are not plain bars. | I want the chocolate flavour specified by the recipe, without an extra filling or crunchy piece changing the bake. |
| Allergens | Check the current ingredients and allergen statement for the exact bar. Do not treat a vegan-recipe claim as confirmation that a product suits someone with a milk allergy. | When I bake for someone with an allergy, I need to check the particular product I will use, not just its front-of-pack description. |
Wafer, caramel, peanuts or meringue pieces add ingredients and texture that a recipe for melted dark chocolate may not allow for.
For cake batter, frosting or a ganache-style component, check the ingredients and choose an unfilled bar unless the recipe calls for those additions.
The Vanilla Valley’s baking guidance describes dark chocolate as less sweet and more cocoa-intensive than milk chocolate, so the substitution can change the cake’s flavour.
Use the chocolate type specified in the recipe where possible. If changing it, consider whether the recipe is intended for that cocoa percentage before changing other ingredients too.
Lindt states that its COOKING 70% bar is made to a vegan recipe but is not suitable for people with a milk allergy because it is made in a facility using milk.
For an allergy, follow the current product’s allergen statement rather than relying on a vegan description alone.
These brand examples illustrate different bar formats; a brand name alone does not tell you whether a particular product suits your recipe.
Lindt sells a COOKING 70% Chocolate Bar in a 200g format.
Waitrose lists Menier Swiss Dark Chocolate as 70% cocoa and describes it as being for desserts and cakes.
Galaxy’s Fusions range includes dark chocolate with raspberry meringue pieces and a stated minimum of 70% cocoa.
Cadbury describes its Darkmilk range as combining cocoa flavour with creaminess.
KitKat’s dark-chocolate products are chocolate-coated wafer bars, not unfilled chocolate bars.
These bars include a dark cooking chocolate and plain dark bars with stated cocoa percentages. Check the recipe before using an ordinary dark bar in place of cooking chocolate.

A plain dark-bar option when the recipe permits ordinary dark chocolate. Its stated cocoa content is 72%, so compare it with the chocolate specified by the recipe and check the current pack for allergens.
No image available
The cooking-chocolate format is relevant when a cake or brownie recipe calls for dark chocolate as an ingredient. It states 70% cocoa; check the current pack’s allergen information before baking for others.
No image available
A 70% dark-bar option if the recipe allows ordinary dark chocolate. Match its cocoa percentage to the recipe rather than assuming it will behave like a cooking bar, and check the current pack for allergens.

Consider this ordinary dark bar only where the recipe permits it and an 85% cocoa level suits the intended flavour. It is not an automatic substitute for a recipe specifying 70% chocolate; check the current pack for allergens.

This plain dark bar states 85% cocoa. Use the recipe’s specified chocolate as your reference before choosing that percentage, and check the current pack for allergen information.
Use the percentage specified by the recipe. If it simply calls for dark chocolate, a plain 70% bar is a practical starting point: Lindt presents its 70% cooking bar for cakes, and Waitrose labels Menier’s 70% bar for desserts and cakes. Check before replacing milk chocolate, as the flavour and sweetness can change.
Not directly when the recipe needs plain melted chocolate. KitKat’s dark bar contains wafer, Snickers lists peanuts and egg white powder, and Mars describes its bar as chocolate with caramel and nougat. Use those formats only when you want their added ingredients in the bake.
Choose it only if you want those additions in the cake. Galaxy describes its dark Fusions bar as containing raspberry meringue pieces, so it will not serve the same role as an unfilled dark bar.
Read the current pack’s ingredients and allergen statement for the exact product. Milk, wheat, peanuts, soya or egg may matter depending on the bar and the person eating the cake; do not infer ingredients from the words “dark chocolate” alone.
Not necessarily. Lindt states that its COOKING 70% bar is made to a vegan recipe but is not suitable for people with a milk allergy because it is made in a facility using milk. Follow the current product’s allergen statement.
