Why it works: Chocolate and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 10,020 recipes. Both carry sotolon, which smells curry, maple. The science ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
Beat the butter and sugar together until creamy.
Add the flour, baking powder, cocoa, and vanilla essence; mix well.
Pour the batter into sandwich tins.
Bake and finish
Bake for 15 to 20 minutes or until a toothpick comes out clean.
Ice with chocolate icing once cooled.

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 a tender crumb and rich flavour.
- Sugar
- Sweetens the cake and helps create a light, creamy texture when beaten with butter.
- Baking powder
- Releases gas as it heats, making the cake rise and become light.
- Cocoa
- Gives the cake its chocolate flavour and colour.
The step that matters
Beat the butter and sugar until creamy. Beating air into the butter and sugar creates tiny bubbles that help the cake rise and give a light texture. Under-beating leaves a dense crumb.
