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 Cream 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.
Prepare
Preheat the oven to 350°F (175°C).
Beat the butter until creamy.
In a separate bowl, beat the egg yolks until thick.
Gradually add the sugar to both mixtures and combine.
Stir in the melted chocolate.
Alternately add the milk and sifted flour mixed with baking powder.
Fold in the beaten egg whites and vanilla extract.
Bake
Pour the batter into two greased cake pans.
Bake for about 18 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and a tender crumb through fat that coats flour and softens the texture.
- Egg yolks
- Add richness and emulsify the batter, helping it hold together smoothly.
- All-purpose flour
- Provides the main structure that sets as the cake bakes.
- Baking powder
- Releases gas in the heat, making the cake rise and become light.
- Egg whites
- Whipped and folded in, they trap air that lifts the batter for a lighter texture.
- Chocolate
- Adds flavor, color and some richness to the batter.
The step that matters
Folding in the beaten egg whites. Egg whites hold air only when whipped well, and overmixing or deflating them while folding makes the cake dense. Fold gently, just until combined, so the trapped air keeps the cake light as it bakes.
