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 batter
Combine chocolate, ½ cup milk, and egg yolk in a saucepan.
Cook over low heat until melted and smooth.
Add butter while mixture still warm and stir until melted.
Once cool, mix in additional ½ cup milk, flour, sugar, baking soda, and vanilla until well combined.
The batter should be slightly thicker than molasses.
Bake and assemble
Divide batter into two greased cake pans and bake at 350°F (175°C) until a toothpick comes out clean.
Once cooled, layer the cakes and frost with white icing.

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.
- Egg yolk
- Adds richness and helps bind the batter into a smooth, tender crumb.
- Butter
- Adds fat for a tender texture and rich flavor.
- Sugar
- Sweetens the cake and helps it brown during baking.
- Baking soda
- Reacts with the batter's acidity to lift and lighten the cake as it bakes.
- Unsweetened chocolate
- Supplies the chocolate flavor and deep color of the cake.
The step that matters
Adding the butter while the chocolate mixture is still warm. If the mixture cools too much, the butter can seize or stay in lumps instead of blending smoothly, leaving the batter uneven. Stirring until fully melted keeps the emulsion smooth.
