Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Chocolate 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).
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 milk and mix thoroughly.
In a separate bowl, combine the flour and baking powder, then gradually add to the wet mixture.
In another bowl, beat the egg whites until stiff peaks form, then fold them into the batter.
Bake and frost
Pour the batter into two long baking tins and bake for about 30-35 minutes or until a toothpick comes out clean.
For the frosting, beat the egg whites to a stiff froth, then gradually add the sugar.
Mix in the grated chocolate and vanilla extract.
Once the cake is cool, frost it with the chocolate mixture.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creaming with sugar traps air and gives the cake a tender, rich crumb.
- Eggs
- Yolks add richness and structure, while whipped whites lighten the batter and help it rise.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas in the oven so the cake rises and becomes light.
- Sugar
- Sweetens the cake and helps it brown while softening the crumb.
- Grated chocolate
- Adds chocolate flavor and body to the frosting.
The step that matters
Folding in the beaten egg whites. Whites hold air only when beaten to stiff peaks. Folding gently keeps that air in the batter; stirring vigorously deflates it and leaves the cake denser.
