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 and Vanilla 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 the vanilla layers
Preheat the oven to 350°F (175°C).
In a bowl, cream together the sugar and butter.
Add the milk, corn starch, flour, baking powder, and vanilla extract. Mix well.
In a separate bowl, beat the egg whites until frothy and fold them into the batter.
Divide the batter into 2 or 3 layers and bake until done.
Make the chocolate layers
For the chocolate cake, cream together the sugar and butter.
Add the milk, flour, baking powder, and egg yolks. Mix well.
Bake in round pie tins in 5 layers.
Make the frostings and assemble
For the frosting, beat the egg whites until you can turn the plate upside down. Gradually add the powdered sugar and mix until smooth.
For the chocolate frosting, beat the egg whites until light, then add powdered sugar and melted chocolate.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Beaten whites fold in air, giving the vanilla layers a light, airy crumb.
- Butter
- Creamed with sugar, it traps air and adds tenderness and richness to the cake.
- Flour
- Forms the cake's structure as its proteins set during baking.
- Baking powder
- Releases gas during baking, helping the layers rise.
- Egg yolks
- Add richness and moisture to the chocolate layers.
- Chocolate
- Gives the chocolate layers and frosting their flavor and color.
The step that matters
Beating the egg whites. Whites must be beaten to the right stiffness and folded in gently. Under-beaten whites give a dense cake, while over-beaten whites turn dry and collapse, so the batter loses its lift.
