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 ↓
Caramel Cake
Ingredients
Directions
Make the chocolate mixture
Melt ½ cake Baker's chocolate with ½ cup milk, the yolk of 1 egg, and 1 cup sugar. Cook until smooth and let cool.
Make and bake the batter
In a bowl, mix 1 cup sugar, ½ cup butter, 2 eggs, ½ cup milk, 2 cups flour, and 2 teaspoons baking powder. Flavor with vanilla.
Add the cooled chocolate mixture to the batter and bake in layers.
Make the filling and coating
Beat the whites of 2 eggs with an equal amount of water until frothy.
Gradually add 2 pounds of confectioner's sugar to the egg whites until very thick.
Spread the filling ½ inch thick between the layers.
Melt ½ cake chocolate with 1 cup sugar and ½ cup milk.
Flavor the melted chocolate with vanilla and boil until creamy.
Pour the coating over the cake.

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.
- Butter
- Adds fat for a tender texture and rich flavor in the cake.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Egg whites
- Whipped with water and sugar to form a thick, stable filling.
- Baker's chocolate
- Gives the cake its chocolate flavor and colors the batter and coating.
The step that matters
Adding the confectioner's sugar to the egg whites. Sugar must be added gradually while beating, so the whites can hold air and reach a thick, stable texture instead of collapsing or staying loose.
