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 ↓
Nice 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.
Make the cake
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter.
Add the egg whites and mix well.
Stir in the milk, baking powder, and flour until combined.
Add vanilla flavoring and mix again.
Divide the batter into three or four layers and bake until golden.
Make the custard
For the custard, combine the egg yolks, sugar, milk, butter, and cornstarch in a saucepan.
Cook over medium heat, stirring until thickened.
Make the icing
For the icing, boil the sugar and water together.
Add the hot syrup to the beaten egg whites and mix until glossy.
If desired, add chocolate or cocoa to the icing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trap air and set the structure, while yolks thicken the custard.
- Butter
- Adds fat for a tender crumb and rich flavor.
- Flour
- Forms the cake's structure once its proteins set during baking.
- Sugar
- Sweetens the cake and helps it brown, and dissolves into the icing syrup.
- Baking powder
- Releases gas during baking so the layers rise.
- Cornstarch
- Thickens the custard as it heats with the milk.
The step that matters
Adding the hot syrup to the egg whites. The syrup must be boiled to the right temperature and poured in a thin stream while beating. This cooks the egg whites into a stable, glossy foam. Pouring too fast or using under-cooked syrup can leave the icing runny or loose.
