Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. 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 the butter and sugar together until light and fluffy.
Add the flour and baking powder, mixing until well combined.
In a separate bowl, beat the egg whites until stiff peaks form, then gently fold them into the batter.
Pour the batter into jelly cake pans and bake until a toothpick comes out clean.
Make the filling
For the filling, combine brown sugar, cream, and butter in a saucepan.
Cook over medium heat, stirring constantly, until thickened.
Remove from heat and stir in vanilla to taste, then let cool before using.

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 trap air and add richness and tender texture.
- Egg whites
- Whipped to stiff peaks, they lighten the batter and give the cake structure as they set.
- Flour
- Forms the cake's structure once mixed and baked.
- Baking powder
- Releases gas during baking, helping the cake rise and become light.
- Brown sugar
- Melts and cooks with cream into a caramel filling with deep, toffee-like flavour.
- Cream
- Adds fat and moisture to the filling, helping it thicken into a smooth caramel.
The step that matters
Cooking the caramel filling. Stirring constantly over medium heat keeps the sugar and cream from scorching or forming lumps, while the mixture thickens as water evaporates and sugars concentrate.
Swap the vanilla
How well each one fits the dish's main ingredients (butter, sugar, flour, egg, cream):
- Vanillathe original
- Raisinfits about as well
- Coconutfits less well
- Figfits less well
Fit is the average pairing score against butter, sugar, flour, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
