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 the butter and sugar together until light and fluffy.
Add the milk, flour, cornstarch, egg whites, and baking powder; mix until smooth.
Pour the batter into a long pan and bake until a toothpick comes out clean.
Make the caramel and finish
In a saucepan, combine the brown sugar, chocolate, and milk; cook until thick enough to spread.
Stir in the vanilla and mix thoroughly.
Spread the caramel mixture 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
- Butter
- Adds fat and richness, and helps make the cake tender.
- Egg whites
- Provide structure and lift as they set in the baked batter.
- Baking powder
- Releases gas that makes the cake rise and turn light.
- Flour
- Forms the main structure of the cake batter.
- Brown sugar
- Gives the caramel its deep flavour and moisture.
- Chocolate
- Adds richness and flavour to the caramel layer.
The step that matters
Cooking the caramel mixture. The caramel must be cooked until thick enough to spread, because sugar and milk thicken as water evaporates and the mixture cools. Undercooked caramel stays runny and soaks into the cake, while overcooked caramel turns stiff and grainy.
