Why it works: Vanilla and milk 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 batter
Cream together the butter and sugar.
Slowly add the milk, then mix in the flour combined with baking powder.
Fold in the well-beaten egg whites and vanilla extract.
Bake and ice
Bake in layer pans lined with greased parchment paper at 350°F (175°C).
For the caramel icing, boil the brown sugar, cream, and butter until it holds together in cold water.
Remove from heat and stir in the vanilla extract.
If the icing curdles, strain and boil again.
Spread the icing between the layers and on top of the cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to give the cake tenderness and a rich flavor.
- Egg whites
- Folded in to trap air and give the cake its light, risen structure.
- Baking powder
- Releases gas in the batter so the cake rises in the pans.
- Flour
- Forms the structure that holds the cake's crumb together as it bakes.
- Brown sugar
- Forms the caramel icing and adds its deep, toffee-like sweetness.
- Cream
- Adds richness and fat to the caramel icing, helping it set smoothly.
The step that matters
Boiling the caramel icing. Sugar boiled with cream and butter can curdle or turn grainy if the mixture is overheated or stirred unevenly. Boiling only until it holds together in cold water reaches the right sugar concentration for a smooth, set icing.
