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.
Make the cake layers
Preheat the oven to 350°F (175°C).
In a bowl, cream together the sugar and butter.
Add the milk and eggs, mixing well.
Stir in the baking powder and flour until combined.
Pour the batter into thin layers in prepared pans and bake until golden.
Make the filling
For the filling, combine the grated chocolate, sweet milk, sugar, egg yolk, and vanilla in a pan over boiling water.
Cook until thickened like jelly, then let cool.
Assemble
Spread the filling between the baked layers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the cake's crumb together as it bakes.
- Eggs
- Add structure and richness, helping the batter set as it bakes.
- Butter
- Adds fat and tenderness, and helps trap air when creamed with sugar.
- Sugar
- Sweetens the cake and helps tenderize the crumb while creaming.
- Baking powder
- Releases gas during baking so the layers rise.
- Sweet chocolate
- Provides the chocolate flavor and body of the filling.
The step that matters
Cook the filling until thickened. The egg yolk must be heated gently over simmering water so it thickens the mixture without scrambling. Stop cooking once it is jelly-like, since it firms further as it cools.
