Why it works: Cocoa and vanilla work together. They rank in the top 4% of all ingredient pairs, and cooks put them together in 357 recipes. Both carry sotolon, which smells curry, maple. The science ↓
Delicious Chocolate Cake
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the cake
Preheat the oven to 400°F (200°C).
Beat the butter until creamy, then gradually mix in the flour, sugar, and well-whisked eggs.
Pour the batter into two well-buttered round cake pans.
Bake immediately for about 25-30 minutes or until a toothpick comes out clean.
Make the chocolate filling
In a saucepan, boil the cocoa and cornflour in a little milk until thick, adding 2 teaspoons of sugar.
Stir in the vanilla extract.
Assemble and finish
Once the cakes are baked, spread a layer of the chocolate mixture between the two cakes.
Sprinkle sifted sugar on top of the cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure and richness as they set during baking.
- Butter
- Adds fat and tenderness, and helps create a creamy batter texture.
- All-purpose flour
- Provides the main structure that sets as the cake bakes.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Cornflour
- Thickens the cocoa mixture into a spreadable filling.
- Cadbury’s cocoa
- Gives the cake and filling their chocolate flavour and colour.
The step that matters
Bake immediately after pouring the batter. Baking powder starts releasing gas as soon as it gets wet, so delaying the oven can lose lift and leave a denser cake.
Swap the cocoa
How well each one fits the dish's main ingredients (sugar, flour, butter, milk, vanilla, egg):
- Almondfits better
- Chestnutfits better
- Hazelnutfits about as well
- Cocoathe original
Fit is the average pairing score against sugar, flour, butter, milk, vanilla, egg. Candidates are from the same food group and used in at least 100 recipes.
