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
Cream together the sugar and butter.
Add the sweet milk and mix well.
Stir in the flour, egg whites, and baking powder until combined.
Bake in layers at 350°F (175°C) until golden.
Make the caramel and assemble
For the caramel, combine grated chocolate, eggs, brown sugar, vanilla, and sweet milk in a saucepan.
Stir while boiling until thickened.
Spread the caramel 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
- Butter
- Adds fat and richness, giving the cake a tender crumb.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Egg whites
- Help the batter set and add lift and structure to the cake.
- Baking powder
- Releases gas during baking, helping the layers rise.
- Grated chocolate
- Adds bitter chocolate flavour and body to the caramel filling.
- Brown sugar
- Adds sweetness and molasses flavour to the caramel and helps it thicken.
The step that matters
Stirring the caramel while it boils. The filling thickens as the eggs and sugar cook together, and stirring keeps the mixture from scorching or setting lumpy on the bottom of the pan.
