Why it works: Milk and butter 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 the butter and sugar together until light and fluffy.
Add the egg yolks and sweet milk, mixing well.
In another bowl, combine the flour and baking powder, then gradually add to the wet mixture.
Divide the batter in half.
To one half, add the grated chocolate and mix well.
Bake and assemble
Pour the plain batter into one greased cake pan and the chocolate batter into another.
Bake for 25-30 minutes or until a toothpick comes out clean.
Once baked, layer the cakes alternately and spread with chocolate icing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks add richness and moisture, and help bind the batter into a tender structure.
- Butter
- Adds richness and flavour, and helps create a tender crumb when creamed with sugar.
- Sugar
- Sweetens the cake and, when creamed with butter, traps air that helps the cake rise.
- Flour
- Provides the main structure that holds the cake together as it bakes.
- Baking powder
- Releases gas during baking, lifting the batter so the cakes rise.
- Grated chocolate
- Adds chocolate flavour and darkens the colour of one cake layer.
The step that matters
Creaming the butter and sugar. Beating softened butter with sugar until light and fluffy traps air in the fat, which helps the cake rise and gives a tender crumb. Cream until the mixture looks visibly lighter before adding the eggs and milk.
