Why it works: Cocoa and vanilla work together. They rank in the top 4% of all ingredient pairs, and cooks put them together in 357 recipes. Both carry sotolon, which smells curry, maple. The science ↓
Cocoa 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.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
Cream the butter and sugar together until light and fluffy.
Add the egg yolks one at a time, mixing well after each addition.
Stir in the cocoa, milk, vanilla, baking powder, flour, and salt until combined.
Gently fold in the beaten egg whites last.
Bake
Pour the batter into a greased cake pan and bake for 25-30 minutes or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks enrich the batter and whites, beaten and folded in, add lift and a light texture.
- Butter
- Creamed with sugar, it traps air and adds fat for a tender crumb and rich flavor.
- Sugar
- Creamed with butter, it helps build a light structure and adds sweetness and browning.
- Baker's cocoa
- Provides the chocolate flavor and color of the cake.
- Bread flour or pastry flour
- Forms the structure that holds the cake's crumb together as it bakes.
- Baking powder
- Releases gas during baking, helping the cake rise and become airy.
The step that matters
Folding in the beaten egg whites. Stirring them in vigorously knocks out the air they hold, so the cake bakes up denser and flatter. Folding gently keeps the foam intact for lift.
