Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chocolate
- Gives the cake its dark colour and rich chocolate flavour.
- Eggs
- Bind the batter and add structure as the cake sets.
- All-purpose flour
- Provides the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas during baking, helping the cake rise and become light.
- Butter
- Adds fat for a tender crumb and rich flavour.
- Brown sugar
- Sweetens the cake and adds moisture and a caramel note.
The step that matters
Boil the chocolate mixture until thick. The chocolate and milk must thicken fully before cooling, since a thin mixture will make the batter loose and wet. Cooling it before adding prevents the eggs and butter from separating or scrambling.
