Home bakers making cakes, brownies or traybakes
If the recipe calls for melted chocolate or pieces folded into batter, check whether it specifies a cocoa percentage. Buttons and chunks are already portioned; a bar may need chopping.
Who is this for?
People baking for guests with allergen requirements
Read the exact pack’s ingredients and precautionary allergen statements. A dark chocolate or vegan-recipe label alone does not establish suitability for someone with a milk or other allergy.
Shoppers who want chocolate to share and bake with
Check that the sharing product contains plain solid chocolate if it will go into the recipe. A box of coated wafers or filled chocolates serves a different purpose from a pouch of plain buttons.
What should you check?
Start with the recipe’s required form and cocoa percentage, then check the ingredients and allergen information on the product you intend to use.
| Priority | What to check | Your needs |
|---|---|---|
| Piece format | Check whether the recipe calls for melted chocolate or pieces. Buttons, chips and chunks come as pieces; a bar may need chopping. | I want pieces to fold into batter or use for decorating without chopping a bar first. |
| Cocoa percentage | Follow a stated recipe percentage where possible. Product examples in this category include M&S chunks with 47% minimum cocoa solids, Montezuma's 60% buttons and plain 70% bars; they are not interchangeable by name alone. | My recipe specifies a cocoa percentage, or I need to consider how changing it will affect the intended flavour. |
| Plain chocolate | Read the ingredient list, especially on sharing boxes. Lindt describes its Choco Wafer Dark Chocolate Sharing Box as wafer with chocolate-based filling and dark-chocolate coating, rather than solid plain chocolate. | I need chocolate to melt into a cake or icing, not a filled sweet to serve alongside it. |
| Allergens | Check both ingredients and precautionary statements on the current pack. The Food Standards Agency explains that “may contain” labelling indicates that an allergen could be unintentionally present. | When I bake for someone with an allergy, I need to check the specific product rather than rely on “dark” or “vegan”. |
| Pack size | Compare the labelled weight with the amount your recipe requires. A sharing pouch does not necessarily contain the same quantity as a bar or baking-chocolate pack. | I want enough plain chocolate for the bake while keeping any chocolate intended for sharing separate. |
Common buying mistakes
-
Choosing a filled sharing box as plain baking chocolate
Lindt’s Choco Wafer Dark Chocolate Sharing Box contains wafer, chocolate-based filling and a dark-chocolate coating. Its composition differs from the plain chocolate a recipe may call for.
For a recipe requiring plain chocolate, check the ingredients and choose a solid product without wafer or filling.
-
Swapping cocoa percentages without checking the recipe
The cited M&S chunks contain at least 47% cocoa solids, while Montezuma’s Giant Dark Chocolate Buttons state 60% and the cited M&S baking chocolate states at least 70%. Changing between them can change the intended flavour.
Use the recipe’s specified percentage where possible, and check that a substitute is plain chocolate rather than filled confectionery.
-
Using a vegan label as an allergen check
Lindt says its EXCELLENCE Dark 70% bar is made to a vegan recipe but is not suitable for people with a milk allergy because it is manufactured in a facility that uses milk.
Read the current pack’s full ingredient and allergen information before baking for someone with an allergy.
-
Relying on the product title for an exact cocoa percentage
Montezuma’s Organic Dark Chocolate Buttons have “74%” in the product-page title, while the ingredient panel on that page states 70% cocoa solids.
If your recipe needs an exact percentage, check the physical pack or confirm the current specification before choosing those buttons.
Relevant brand references
These examples show how format, cocoa declaration and allergen wording differ between specific products; a brand name alone does not settle which chocolate suits a recipe.
Montezuma’s
Its 120g plain dark-chocolate button pouches offer a sharing format that can also be used as pieces in a bake.
- Giant Dark Chocolate Buttons state 60% cocoa solids and list cocoa mass, sugar, cocoa butter, soya lecithin and vanilla.
- For the Organic Dark Chocolate Buttons, the product-page title and ingredient panel give different cocoa percentages; check the pack if the exact figure matters.
M&S
Its cited dark cooking chocolate and dark chocolate chunks are presented for baking uses, but differ in form and cocoa content.
- The cited cooking chocolate states at least 70% cocoa solids; the ready-portioned chunks state at least 47%.
- Allergen information differs between the products. Check the current pack rather than applying one product’s warning to the other.
Lindt
Lindt describes its EXCELLENCE Dark 70% bar as suitable for baking and cooking; its Choco Wafer sharing box is a different type of confectionery.
- The EXCELLENCE Dark 70% bar states a minimum of 70% cocoa solids.
- Lindt says this vegan-recipe bar is not suitable for people with a milk allergy. The Choco Wafer box contains wafer and filling, so it is not plain baking chocolate.
Divine
Its cited 90g plain 70% dark-chocolate bar is an option when a recipe calls for a bar rather than ready-portioned pieces.
- The listed ingredients include cocoa mass, sugar, cocoa butter, sunflower lecithin and vanilla.
- The product states that it may contain gluten, milk and nuts; its bar format may require chopping for recipes calling for pieces.
Green & Black’s
Its cited 90g organic 70% dark-chocolate bar provides a plain-bar format rather than a pouch of buttons.
- The Ocado listing states 70% cocoa solids and lists cocoa mass, cane sugar, cocoa butter and vanilla extract.
- The listing carries may-contain statements for nuts and milk; check the current pack when baking for others.
Hotel Chocolat
Its cited dark-chocolate slab products are labelled 70% and 85% and offer a breakable slab format rather than a button pouch.
- The labelled cocoa percentages let you compare the slabs with a recipe’s stated requirement.
- Check the current product’s ingredients and allergen information, particularly for an allergy-sensitive bake.
Joybuy options for cake baking

Frequently asked questions
Can I melt a dark-chocolate sharing box into a cake?
Use it as a substitute for plain dark chocolate only if its contents match what the recipe calls for. Lindt’s Choco Wafer Dark Chocolate Sharing Box contains wafer and filling beneath a dark-chocolate coating, so it is not equivalent to solid plain chocolate.
Should I use 60% or 70% dark chocolate for a cake?
Follow the recipe’s stated cocoa percentage if it gives one. If it does not, consider the flavour you want: the cited Montezuma’s buttons state 60% cocoa solids, while the cited M&S cooking chocolate states at least 70%; also check their ingredients and formats before substituting.
Does vegan dark chocolate suit someone with a milk allergy?
Not necessarily. Lindt says its vegan-recipe EXCELLENCE Dark 70% bar is not suitable for people with a milk allergy because it is made in a facility that uses milk. Check the current product’s full allergen information.
What does “may contain” mean on a chocolate pack?
The Food Standards Agency explains that precautionary allergen wording such as “may contain” communicates that an allergen could be unintentionally present. For a bake intended for someone with an allergy, check the current label against that person’s requirements.
Do I need to chop a chocolate bar for cake batter?
Chop it if the recipe calls for pieces of a size the bar does not provide; follow the recipe’s instructions if it calls for melted chocolate instead. Buttons, chips and chunks are already in pieces, though their cocoa percentages and ingredients still need checking.
