Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. 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 batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the egg whites and mix well.
Stir in the milk, flour, corn starch, baking soda, and cream of tartar until combined.
Make the caramel
For the caramel, combine the brown sugar, chocolate, butter, and milk in a saucepan.
Boil for five minutes, then add vanilla extract.
Bake
Pour the caramel over the cake batter in shallow pans.
Bake until a toothpick inserted in the center comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Provide structure and lift as they set in the oven.
- Flour
- Forms the main structure of the cake as it sets.
- Butter
- Adds richness and tenderness to the cake and caramel.
- Brown sugar
- Gives the caramel its molasses flavour and moisture.
- Baking soda
- Reacts with acid in the batter to help the cake rise.
The step that matters
Boil the caramel for five minutes. Boiling cooks the sugar and milk to a thick, set caramel. Boiling too briefly leaves it runny, while boiling too long can make it hard or grainy once it cools.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
