Choose a solid cooking-chocolate block when the biscuit recipe calls for melted chocolate: dark chocolate gives a more cocoa-forward flavour, while milk chocolate gives a sweeter profile. A 360 g milk-chocolate sharing bar offers more chocolate in one bar, but check that its flavour and ingredients suit the recipe rather than assuming it is interchangeable with cooking chocolate.
If a recipe needs more than one small bar, compare the required weight with the pack size. Sainsbury's lists 200 g dark and milk cooking blocks; Cadbury and Galaxy each list a 360 g milk-chocolate bar. The larger bars are not presented as purpose-made cooking chocolate.
Decide whether the recipe calls for dark or milk chocolate before choosing by size. M&S describes dark baking chocolate with 70% to 100% cocoa solids as more intense and bitter, and milk and white chocolate as sweeter.
Check the current pack before adding chocolate to a shared batch. Milk and soya ingredients, as well as precautionary milk-allergen statements, differ between the cooking chocolates described by Sainsbury's and Dr. Oetker.
Start with the ingredient format specified by the recipe, then compare flavour, quantity and the current pack information.
| Priority | What to check | Your needs |
|---|---|---|
| Recipe format | Check whether the recipe calls for solid chocolate, cocoa powder or drinking chocolate. For solid chocolate, look for a bar or block suitable for the intended use. | I'm melting chocolate into dough or using it for a filling or drizzle, so I need a solid product rather than drinking-chocolate powder. |
| Flavour | Compare dark and milk chocolate, including stated cocoa and milk solids. Sainsbury's lists at least 55% cocoa solids for its dark 200 g cooking block and at least 35% cocoa solids and 18% milk solids for its milk 200 g block. | For a recipe designed around dark chocolate, I want its cocoa-forward flavour. If a sweeter milk-chocolate result is the aim, I'll choose that deliberately rather than substituting by bar size. |
| Quantity | Match the recipe's required weight to the pack. Compare 100 g baking bars, 200 g cooking blocks and 360 g milk-chocolate bars without assuming they have the same recipe role. | One batch may need only part of a block; for several batches, I want to know how many bars to buy and how much will remain. |
| Melting method | Read the product's instructions for heating and stirring. Sainsbury's dark cooking-chocolate directions specify an initial 30 seconds in the microwave, followed by stirring and 10-second bursts. | I'll be melting the chocolate for biscuit dough or decoration, so instructions for that method matter to me. |
| Ingredients and allergens | Check the current ingredients and precautionary allergen wording, including milk and soya. Do not treat a dark-chocolate name or vegan-recipe description as an allergy assurance. | If I'm baking for someone with an allergy, the actual pack information needs to suit that person before I use the chocolate. |
Drinking-chocolate powder and a solid block have different ingredient formats and recipe roles. A spoon-for-spoon substitution may change the intended mix.
Use solid chocolate when the recipe calls for it; use cocoa powder when the recipe specifies cocoa powder or gives a tested substitution.
Cadbury Dairy Milk and Galaxy's researched 360 g bars are milk-chocolate bars, not products presented as cooking chocolate. Their milk-chocolate profile may not suit a recipe written for dark chocolate.
Check the chocolate type in the recipe first. Choose a large milk bar when that flavour and format are intentional.
Dr. Oetker's 100 g dark cooking bar may contain milk despite being prepared to a vegan recipe. Sainsbury's also gives a milk cross-contact warning for its dark cooking block.
Read the current pack's ingredients and precautionary statements before baking for someone with an allergy.
Cooking-chocolate instructions call for controlled heating and stirring; Dr. Oetker's guidance also warns against getting water into the chocolate.
Break the chocolate into pieces and follow its stated melting method, keeping the bowl and utensils dry.
These references describe particular products or ranges, not every chocolate made by each brand.
Its Belgian cooking-chocolate range includes 200 g dark and milk blocks.
Its 100 g dark cooking-chocolate bar is presented for baking, covering and decoration.
Cadbury describes its Dairy Milk 360 g product as a large milk-chocolate bar.
Its 360 g gift bar is another large-format milk-chocolate option.
Its cooking-chocolate and cocoa range provides options across chocolate types and powdered cocoa.
This option is a dark cooking-chocolate bar for biscuit recipes calling for solid dark chocolate. Check the recipe quantity: it is a 100 g bar rather than a larger block.

For a biscuit recipe calling for solid dark chocolate, compare this 100 g bar with the amount required. Its name specifies 70% cocoa; the listing identifies milk and says it may contain eggs, gluten and tree nuts, so check the current pack before serving anyone with an allergy.
Do not assume a direct substitution. Solid cooking chocolate, cocoa powder and drinking-chocolate products have different formats and uses; follow a biscuit recipe that specifies the powder or provides a tested substitution.
Follow the directions on the product you buy. Sainsbury's dark cooking block instructs you to break it into pieces, heat it in the microwave for 30 seconds, stir, then continue in 10-second bursts until melted; Dr. Oetker's guidance warns against overheating or getting water into melting chocolate.
No. Sainsbury's dark cooking block carries a milk cross-contact warning, and Dr. Oetker's dark cooking bar may contain milk. Check the current pack's allergen and precautionary wording before using either for someone with a milk allergy.
Not necessarily: weigh the chocolate the recipe requires first. Sainsbury's lists 200 g cooking blocks, whereas the Cadbury and Galaxy 360 g products described here are milk-chocolate sharing or gift bars rather than purpose-made cooking blocks.
Read the current chocolate pack's ingredients and allergen information, including precautionary statements, against the needs of the people eating the biscuits. Do not rely on a dark-chocolate name or a vegan-recipe description alone.
