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
Make the cake
Melt the chocolate and mix it with ½ cup of milk; let it cool.
Cream the sugar and butter together.
Add the yolks of the eggs, then the beaten egg whites, and the remaining ½ cup of milk.
Mix in the flour and baking powder, then add the cooled chocolate mixture.
Bake in three layers.
Make and assemble the filling
For the filling, boil 1 cup of sugar, ⅓ cup of milk, and 1 tablespoon of butter for 5 minutes.
Beat the filling until cool, then add 1 teaspoon of vanilla.
Spread the filling between the layers of cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trap air for lift and yolks add richness and structure to the crumb.
- Flour
- Forms the gluten network that gives the cake its structure.
- Baking powder
- Releases gas in the batter so the layers rise and become light.
- Butter
- Creaming with sugar traps air and adds tenderness and richness.
- Sugar
- Sweetens the cake and helps tenderize the crumb while creaming aerates the batter.
- Sweet chocolate
- Provides chocolate flavour and deep colour to the batter.
The step that matters
Adding the cooled chocolate mixture. If the chocolate is still hot when added, it can cause the butter to melt out of the creamed batter and weaken the air structure, so letting it cool first keeps the batter stable and the layers light.
