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 ↓
Chocolate 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 eggs one at a time, mixing well after each addition.
In a separate bowl, combine the flour and baking powder.
Gradually add the dry ingredients to the creamed mixture, alternating with the milk.
Pour the batter into jelly tins and bake until a toothpick comes out clean.
Make the caramel
For the caramel, combine the brown sugar, cake chocolate, and milk or water in a saucepan.
Add butter and boil for 20 minutes or until thick enough.
Spread the caramel between the layers of cake while warm.
Make the frosting
For the frosting, beat the egg whites until stiff peaks form.
Gradually add powdered sugar, vanilla, and grated chocolate, mixing until smooth.
Frost the top of the cake with the prepared frosting.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Add structure and richness to the batter as they set during baking.
- Flour
- Provides the structure that holds the cake's crumb together.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Butter
- Adds tenderness and flavor to the cake by coating the flour and enriching the crumb.
- Sugar
- Sweetens the cake and helps it brown while creaming aerates the batter.
- Egg whites
- Whipped into stiff peaks to give the frosting its airy, light volume.
The step that matters
Boil the caramel until thick. Sugar and milk must cook long enough to reach a thick, spreadable consistency. Undercooked caramel stays runny and soaks into the layers, while overcooked caramel can turn grainy or hard once it cools.
