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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the batter
Preheat the oven to 350°F (175°C).
In a bowl, beat the eggs and mix in the sugar and butter until creamy.
Add the baking powder, milk, and flour, mixing until smooth.
Flavor the batter with lemon or vanilla extract.
Pour the batter into a greased cake pan and bake for 25-30 minutes.
Make the filling
For the filling, combine brown sugar, chocolate, and milk in a saucepan.
Add butter and vanilla, then cook over medium heat until thick enough to spread.
Assemble
Once the cake is cool, spread the filling between the layers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure as they set during baking.
- Butter
- Adds richness and tenderness to the cake crumb.
- Baking powder
- Releases gas that makes the cake rise in the oven.
- Flour
- Forms the structure of the cake as it bakes.
- Brown sugar
- Adds moisture and deep caramel flavor to the filling.
- Chocolate
- Adds richness and body to the filling.
The step that matters
Cook the filling until thick enough to spread. The filling thickens as sugar and milk cook down and cool. Stopping too early leaves it runny, while overcooking can make it grainy or stiff once cool.
