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
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 butter and sugar.
Add the milk, flour, corn starch, and baking powder to the mixture.
In a separate bowl, beat the egg whites until stiff and fold them into the batter.
Pour the batter into a long pan and bake until golden.
Make the caramel and finish
For the caramel topping, combine brown sugar, chocolate, milk, and butter in a saucepan.
Cook the mixture until it thickens enough to spread.
Spread the caramel on the cake and return it to the oven to dry.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped egg whites give the cake lightness and an airy, open structure as they set in the oven.
- Flour
- Provides the structure that holds the cake together as the batter sets while baking.
- Butter
- Adds richness and tenderness to the cake and helps build the caramel's smooth, spreadable body.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Brown sugar
- Gives the caramel topping its deep sweetness and molasses flavor.
- Chocolate
- Adds bitter depth and color to the caramel topping.
The step that matters
Cook the caramel until it thickens enough to spread. Caramel thickens as its sugar concentrates and cools. Undercooked caramel stays runny and soaks into the cake, while overcooked caramel becomes hard and grainy once cool.
