Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Chocolate Marble 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).
Make the batter
Cream the butter and sugar together until light and fluffy.
Add the beaten egg yolks and mix well.
Stir in the sweet milk.
Sift the flour with the baking powder and gradually add to the mixture.
In a separate bowl, beat the egg whites until stiff and fold them into the batter.
Take out 1 cup of the batter and mix in the melted chocolate and 1 tablespoon of sweet milk.
Bake and finish
In a greased cake tin, alternate layers of the plain batter and the chocolate batter.
Bake until a toothpick inserted in the center comes out clean.
Ice with white or chocolate icing, or both as preferred.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air and give a tender, rich crumb.
- Sugar
- Sweetens the cake and helps hold air when creamed with butter.
- Eggs
- Provide structure and richness, and the whites add lift when beaten and folded in.
- All-purpose flour
- Builds the cake's structure as its proteins set during baking.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Grated chocolate
- Adds chocolate flavour and the dark colour of the marbled layers.
The step that matters
Folding in the beaten egg whites. Stiffly beaten whites hold the air that lifts the batter. Overmixing or stirring them vigorously deflates the foam, leaving a denser cake, so fold gently until just combined.
