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 your oven to 350°F (175°C).
In a large bowl, cream together the butter and sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the milk and baking powder, then gradually add the flour until well combined.
Marble and bake
Take out 1 cup of the batter and mix in the grated chocolate with a little milk.
In a greased cake mold, pour in about 1 inch of the yellow batter.
Drop spoonfuls of the chocolate mixture onto the yellow batter, spreading it in broken circles.
Bake in the preheated oven until a toothpick inserted in the center comes out clean.

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, giving the cake a light, tender crumb.
- Eggs
- Add structure and richness as they set during baking, binding the batter.
- All-purpose flour
- Forms the main structure of the cake as its proteins set in the oven.
- Baking powder
- Releases gas in the batter, helping the cake rise and become airy.
- Sugar
- Sweetens the cake and helps create a soft, tender texture when creamed with butter.
The step that matters
Drop the chocolate batter gently onto the yellow batter. Spreading the chocolate in broken circles rather than stirring it through keeps distinct dark and light swirls. Overmixing blends the layers and turns the marbling into an even brown color.
