Cookie, brownie and traybake makers
Plain buttons give you small pieces to portion and fold through a mixture without chopping a bar. Check that their cocoa percentage and ingredients fit the recipe.
Who is each format for?
Bakers making chocolate-led cakes, ganache or sauces
When chocolate is a major ingredient, start with the recipe’s required weight and cocoa percentage. A cooking bar with those details stated may be a more useful choice than a mixed sharing assortment.
Bakers checking dietary and allergen information
Read the current pack’s ingredients and precautionary statements for the exact chocolate you plan to use. A general description such as “dark” does not establish whether it meets someone’s dietary requirements.
What should you check?
Start with the recipe’s chocolate quantity and cocoa percentage, then choose a shape that works for the way you will use it.
| Priority | What to check | Your needs |
|---|---|---|
| Cocoa percentage | Compare the labelled percentage with the recipe. Do not substitute unsweetened chocolate for a sweetened dark chocolate without accounting for the recipe’s sugar. | If chocolate is the main flavour in my cake or ganache, I want the cocoa level the recipe calls for, rather than relying on the word “dark”. |
| Chocolate format | Look for plain, unfilled pieces. Buttons or chips need no chopping for fold-in use; a bar can be weighed and chopped when the recipe calls for it. | For cookies or traybakes, I would rather fold in small pieces. For a measured melted-chocolate mixture, I can prepare a bar if it meets the recipe. |
| Pack quantity | Compare the pack weight with the amount in the recipe, especially for a large batch. Check whether a sharing bag contains plain chocolate or an assortment with fillings. | I need enough of the same chocolate for the whole bake, without assuming that a pack described as “sharing” is intended for baking. |
| Ingredients and allergens | Read the current ingredients, emphasised allergens and precautionary statements on the pack. Check a vegan claim separately from any cross-contact warning. | When baking for someone with a dietary restriction or allergy, I need information for the exact product, not a general claim about dark chocolate. |
What can go wrong?
-
Choosing a filled sharing assortment for a plain-chocolate recipe
Wafers, fillings or mixed flavours can change a bake’s sweetness and texture. “Sharing” describes the pack or eating occasion, not how it will work in a recipe.
Choose plain dark pieces or a plain bar when the recipe calls for chocolate, and check the cocoa percentage.
-
Treating every dark chocolate as interchangeable
A 60% button, a 70% bar and unsweetened chocolate do not have the same cocoa and sugar composition. A swap can change the intended flavour of the bake.
Follow the recipe’s stated percentage where possible. If you need to substitute, check both the cocoa level and whether the recipe accounts for added sugar.
-
Relying on a vegan or dairy-free description alone
Such a description does not replace the ingredient list or precautionary allergen information for the individual product.
Check the current physical pack before baking for someone with an allergy; online product information can change.
-
Using too much heat when melting chocolate
Excess heat can spoil the melted texture, while moisture can make chocolate seize and become grainy.
Hotel Chocolat’s melting guidance recommends low, consistent heat and frequent stirring. Keep the equipment dry and steam out of the bowl.
A seized or burnt batch can mean preparing the chocolate again.

Common questions
Can I use a dark-chocolate sharing bag for baking?
Yes, if it contains plain dark chocolate pieces that fit the recipe’s cocoa level and quantity. Do not treat wafers, filled chocolates or a mixed-flavour assortment as a direct substitute for plain chocolate; their other ingredients can change the result.
Should I choose 60%, 70% or unsweetened chocolate?
Follow the percentage specified by the recipe where one is given. A 60% chocolate and a 70% chocolate will not give the same balance of cocoa and sweetness; Hotel Chocolat describes unsweetened chocolate as cocoa mass and cocoa butter without sugar, so use it when the recipe calls for it or accounts separately for sweetness.
How can I melt dark chocolate without it turning grainy?
Use low, consistent heat, stir frequently and keep the equipment dry. Hotel Chocolat’s melting guidance warns that excess heat can cause separation and moisture can make chocolate seize.
Do I still need to check allergens on vegan dark chocolate?
Yes. Read the exact product’s current ingredients and precautionary statements rather than relying on a vegan description alone. GOV.UK’s allergen-labelling guidance distinguishes allergens used as ingredients; the pack also lets you check any precautionary wording relevant to the person eating the bake.
