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 cake
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the milk and baking powder until combined.
Pour the batter into a greased cake pan and bake for 25-30 minutes.
Make the filling and assemble
For the filling, dissolve the grated chocolate in a small cup of milk and bring to a boil.
Add the sugar, a small piece of butter, a little salt, and flavoring to the chocolate mixture.
Once the cake layers are cool, spread the filling between them.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to trap air, giving the cake a light, tender crumb.
- Eggs
- Add structure and richness, binding the batter as they set in the oven.
- Baking powder
- Releases gas in the batter, helping the cake rise.
- Grated baker's chocolate
- Provides the chocolate flavor and color in the filling.
- Sugar
- Sweetens the cake and helps create a fine, tender texture when creamed.
The step that matters
Cream together the sugar and butter until light and fluffy. Beating sugar and butter traps air in the fat, which expands in the oven and gives the cake lift. Under-creaming leads to a dense cake.
