When a recipe calls for plain dark chocolate, choose a cooking bar or baking chips with a stated cocoa percentage that matches it, rather than substituting a boxed assortment. Assorted chocolates can work as deliberate pieces or toppings if their fillings, flavours and allergens suit the bake, but they are not a like-for-like ingredient.
If a brownie, cake, ganache or sauce recipe specifies dark chocolate, a plain bar with a stated cocoa percentage makes it easier to choose the ingredient the recipe describes. Menier, Lindt and Green & Black's each have reviewed cooking products labelled at 70% cocoa solids.
For cookies or traybakes, chips provide pieces without chopping a bar. Check their stated cocoa percentage against the recipe and read the current allergen label.
A box already in the cupboard can provide chopped pieces or toppings when you want its mixed flavours and centres in the finished bake. Identify the individual chocolates before adding them; an assortment is not a uniform plain-dark ingredient.
Start with the recipe's chocolate requirement, then decide whether you need a plain ingredient, ready-made pieces or the particular fillings in a box.
| Priority | What to check | Your needs |
|---|---|---|
| Cocoa content | Compare the recipe's requirement with the percentage on the exact product. Menier and Lindt describe their reviewed cooking bars as 70% cocoa solids; Nestlé states 35% minimum for the dark chocolate in its reviewed Quality Street tub. | I'm following a recipe that specifies dark chocolate, so I want to know the cocoa level of the ingredient I'll actually use. |
| Fillings | Check whether the chocolates are plain or contain centres. Asda describes Roses pieces with orange crème, caramel and other fillings; Nestlé describes Quality Street as an assortment that includes toffees and fruit creams. | A mixed-flavour topping would suit my bake, but I don't want unexpected centres in its main chocolate ingredient. |
| Format | Choose a bar if the recipe calls for plain chocolate to chop or melt. For pieces, check the cocoa percentage on the chips; Sainsbury's describes the reviewed Food Thoughts 70% chips for cookies and desserts. | For cookies, I'd rather use pieces without chopping a bar. For a recipe specifying a percentage, I'll check that the chips match it. |
| Allergens | Read the current pack's ingredients, declared allergens and any precautionary wording. GOV.UK explains that prepacked foods containing any of the 14 regulated allergens must clearly identify them in the ingredients list. | Someone eating the bake has an allergy, so I need to check the exact chocolate and any fillings, not assume that dark or vegan-recipe chocolate suits them. |
Nestlé states that the dark chocolate in its reviewed Quality Street tub has at least 35% cocoa solids, while Menier and Lindt state at least 70% for their reviewed cooking bars. Those labels describe different ingredients, even though all use the word dark.
Where a recipe gives a cocoa percentage, check the figure on the exact bar, chips or assortment before substituting it.
Roses and Quality Street contain chocolates with different fillings and flavours. Mixing them into the main chocolate ingredient also mixes those centres into the bake.
Use assorted pieces when the recipe deliberately allows mixed confectionery, or keep them as an identifiable topping.
The reviewed Ferrero Rocher Dark 70% bar contains hazelnuts, and precautionary allergen statements differ between cooking bars and chips. A cocoa percentage does not answer an allergen question.
Check the current pack for the exact product before baking for someone with an allergy, including any precautionary wording.

This 70% dark bar may fit a recipe that calls for chocolate at that cocoa level. It is a different variant from the Green & Black's cooking bar discussed above; check the recipe's format requirements and the current pack's nut and milk warnings before buying.
Not as a like-for-like substitute when the recipe relies on plain chocolate with a stated cocoa percentage. Nestlé's reviewed Quality Street tub, for example, contains assorted chocolates and centres, and its dark chocolate is labelled 35% cocoa solids minimum. Use assorted pieces only when their fillings and flavours are intended in the bake.
No: Ferrero says 70% cocoa applies to the bar's outer layer, while the product has a hazelnut and cocoa filling and contains 10% hazelnuts. Choose it for a bake that deliberately calls for that filled, nut-flavoured element, not as a plain 70% bar.
Read the exact product's current ingredients, declared allergens and precautionary wording before using it. GOV.UK explains that prepacked food containing any of the 14 regulated allergens must clearly identify them in the ingredients list; chocolate type and cocoa percentage alone do not establish suitability.
No. Lindt describes its reviewed 70% cooking bar as made to a vegan recipe but warns that it is made in a facility using milk and is not suitable for people with a milk allergy. Check the current pack for the exact product.
Choose chips when the recipe calls for chocolate pieces and you would rather not chop a bar. Check their cocoa percentage if the recipe specifies one; for a recipe calling for plain chocolate to melt, choose a bar that matches the stated ingredient requirements.
