Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Chocolate Layer Cake
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the batter
Preheat the oven to 350°F (175°C).
In a bowl, cream together the sugar and butter.
Add the sweet milk and eggs, mixing well.
Sift the baking powder with the flour and gradually add to the mixture.
Pour the batter into a greased cake pan and bake for 25-30 minutes.
Make the icing and finish
For the icing, boil the sweet milk, sugar, and cake chocolate until thick.
Spread the icing over the cooled cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure that holds the cake together as it bakes.
- Eggs
- Add structure and richness, helping bind the batter and set during baking.
- Baking powder
- Releases gas in the batter, helping the cake rise and become light.
- Butter
- Adds fat for tenderness and flavour, and helps trap air when creamed with sugar.
- Sugar
- Sweetens the cake and helps create a tender crumb when creamed with butter.
- Cake chocolate
- Gives the icing its chocolate flavour and helps it thicken when boiled.
The step that matters
Boiling the icing until thick. Icing that is boiled too briefly stays thin and runny, while over-boiling can make it grainy or stiff. Cooking it to the right thickness is what lets it spread and set on the cake.
