Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. 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.
Prepare
Preheat your oven to 350°F (175°C).
Make the batter
In a bowl, cream together the sugar and butter.
Add the milk, flour, eggs, and baking powder, mixing until smooth.
Make the caramel chocolate filling
In a saucepan, combine the grated chocolate, sugar, and milk.
Cook over medium heat, stirring until thickened.
Remove from heat and stir in the egg yolk.
Allow the chocolate mixture to cool, then stir it into the cake batter.
Bake
Pour the batter into a greased cake pan and bake for 30-35 minutes.

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 together as it bakes.
- Eggs
- Add structure and richness, helping the batter set as it bakes.
- Butter
- Adds fat for tenderness and flavor in the cake crumb.
- Baking powder
- Releases gas when heated, making the batter rise and become light.
- Sugar
- Sweetens the cake and helps it brown during baking.
- Milk
- Adds moisture to the batter and helps it blend into a smooth mixture.
The step that matters
Cook the chocolate mixture until thickened. Stirring over medium heat until thickened is needed to get a smooth, spreadable mixture; cooking too fast can scorch the milk and sugar, and stopping too early leaves it too thin to blend into the batter.
