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 sugar and butter until light and fluffy.
Add the milk and mix well.
Gradually add the flour, baking powder, and baking soda (or cream of tartar).
Beat in the eggs one at a time until well combined.
Pour the batter into greased jelly tins and bake until a toothpick comes out clean.
Make the caramel
For the caramel, melt 2 tablespoons of butter in a saucepan.
Add the brown sugar and milk (or water) and bring to a boil.
Stir in the chocolate and boil for 20 minutes or until thickened.
Pour the caramel over the warm cakes, stacking the layers.
Make the frosting
For the frosting, beat the egg whites until stiff peaks form.
Gradually add 1 ½ cups sugar, vanilla, and grated chocolate, mixing until smooth.
Spread the frosting 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
- Flour
- Provides the structure that holds the cake's rise and crumb together.
- Eggs
- Add structure and richness, helping the batter set as it bakes.
- Baking powder
- Releases gas in the batter, making the cake rise and become light.
- Butter
- Adds fat for tenderness and flavour, and helps trap air when creamed with sugar.
- Brown sugar
- Sweetens the caramel and adds depth of flavour and moisture.
- Egg whites
- Whipped into stiff peaks to create a light, airy frosting.
The step that matters
Boiling the caramel for 20 minutes. Boiling thickens the mixture as water evaporates and sugar concentrates. Stop too early and the caramel stays runny; cook too long and it can set too firm or scorch.
“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.
