Families trying dark chocolate in a bake
If a recipe calls for dark chocolate, compare plain bars around 70% cocoa first, then decide whether the children eating the bake would welcome a stronger cocoa flavour.
Who is this for?
Households managing food allergies
Check the exact bar’s current ingredients and precautionary allergen statement before a child handles the chocolate or eats the bake. Neither “dark” nor “vegan” establishes suitability for a particular allergy.
Bakers who prefer plain ingredients
A plain bar avoids adding an unplanned filling or flavour to the recipe. Organic or Fairtrade credentials may also matter to your household, but they do not replace an allergen check.
What should you check?
Start with the recipe and the flavour your family wants, then check the bar’s ingredients, allergen information and size.
| Priority | What to check | Your needs |
|---|---|---|
| Cocoa flavour | Check whether the recipe specifies a cocoa percentage. Compare a plain 70% bar with 72% or 74% options if you want a stronger cocoa flavour; M&S recommends 70% cocoa for intense baking flavour. | I want the finished bake to suit the children eating it, rather than choosing the highest cocoa percentage by default. |
| Allergens | Read the current ingredient list and any “may contain” statement for the specific allergen. The Food Standards Agency explains that precautionary allergen labelling indicates possible unintended allergen presence. | If a child has an allergy, I need to check the exact bar before it goes into a shared bake. A vegan label alone does not settle milk-allergy suitability. |
| Ingredients | Check whether the bar is plain or contains fillings or added flavours. Read its ingredient list rather than assuming all dark bars have the same composition. | For brownies or cookies, I may want chocolate without an added flavour or inclusion that the recipe does not call for. |
| Bar size | Compare the bar’s stated weight with the quantity in the recipe. The named single-bar options here include 90g, 100g and 125g formats. | I want to know whether one bar supplies the amount my recipe requires before I start baking. |
Common buying mistakes
-
Assuming vegan means suitable for a milk allergy
Lindt says its 70% bar is made to a vegan recipe but is not suitable for people with a milk allergy.
Check both the ingredients and precautionary allergen statement on the exact current pack before using it for a child with a milk allergy.
-
Choosing the highest cocoa percentage automatically
M&S describes 70% cocoa dark chocolate as having an intense baking flavour. A higher-percentage bar may not give the flavour your family expects from the recipe.
When the recipe simply calls for dark chocolate, consider a plain 70% bar first; choose a stronger cocoa profile if it suits the recipe and the people eating it.
-
Skipping “may contain” warnings
The warnings differ between bars: Green & Black’s 70% bar may contain nuts and milk, Divine’s 70% bar may contain gluten, milk and nuts, and Montezuma’s FitzRoy may contain milk, nuts and peanuts.
Check the named allergens on the exact wrapper against the child’s allergy before the chocolate is handled or served.
-
Relying on an older ingredient listing
Ingredients and allergen information can change, so a previously purchased wrapper or online listing may not describe the bar in your hand.
Read the physical wrapper again before baking, particularly when preparing food for someone with an allergy.

Frequently asked questions
What cocoa percentage should I try first for a bake with children?
If the recipe calls for dark chocolate without specifying a percentage, a plain 70% bar is a practical starting point. Lindt describes its 70% bar as suitable for baking and cooking, while M&S recommends 70% cocoa for an intense baking flavour. Consider 72% or 74% if the family already enjoys a stronger cocoa flavour.
Is a vegan dark chocolate bar suitable for a child with a milk allergy?
Not automatically. Lindt states that its 70% bar is made to a vegan recipe but is not suitable for people with a milk allergy. The Food Standards Agency explains that “may contain” labelling indicates possible unintended allergen presence, so check the exact current pack for the child’s allergy.
Should I check the wrapper if I have bought the same bar before?
Yes. M&S advises reading the current label because ingredients and allergen information may change. Check it again before a child handles the chocolate or eats the finished bake.
Do “may contain” warnings matter when chocolate is baked into a recipe?
Yes, when the warning names an allergen relevant to the person eating the bake. The Food Standards Agency says precautionary allergen labelling communicates possible unintended allergen presence; adding the chocolate to a recipe does not remove the need to assess that warning.
Should I use a flavoured bar for brownies or cookies?
Choose a plain bar if the recipe calls for plain dark chocolate and you do not want an added flavour or inclusion. If you prefer a flavoured bar, check its ingredients against the recipe and any allergies before using it.
