Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and 81,283 recipes mention both. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ingredients
Directions
Make the chocolate mixture
Boil together half cup of milk with half a cup of bitter chocolate until thick.
Make the batter
In a separate bowl, combine one and a half cups of sugar, half a cup of butter, half a cup of milk, three eggs, two cups of flour, one teaspoon soda in a little boiling water, and one teaspoon baking powder, then mix part one with part two.
Bake and fill
Bake in layers.
Beat together one and a half tablespoons of butter, one and a half cups powdered sugar, one teaspoon milk, and one teaspoon vanilla until smooth.
Spread filling between layers and on top.

Flour and butter share little aroma chemistry, yet 124,287 recipes mention both: they likely work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the cake as its proteins set during baking.
- Eggs
- Bind the batter and add structure and lift as they set.
- Baking soda
- Releases gas during baking to help the cake rise.
- Baking powder
- Releases gas during baking to help the cake rise.
- Butter
- Adds fat for a tender crumb and richer flavour in the cake and filling.
- Bitter chocolate
- Provides chocolate flavour and dark colour, and thickens when boiled with milk.
The step that matters
Boiling the chocolate and milk until thick. Milk and chocolate can scorch or separate if the heat is too high or they are left unattended. Cooking them until thick gives the mixture the body needed to spread and flavour the cake evenly, so stir steadily while it boils.
