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 ↓
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 together the sugar and butter until light and fluffy.
Add the milk and mix well.
Sift together the flour and baking powder, then gradually add to the mixture.
Take a small portion of the batter and mix in the cocoa powder.
Bake
In a greased loaf pan, alternate layers of the plain batter and the chocolate batter.
Bake for 1 to 1 ½ hours or until a toothpick inserted comes out clean.

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.
- Butter
- Adds fat that gives the cake a tender, rich crumb.
- Sugar
- Sweetens the cake and helps the creamed butter hold air.
- Baking powder
- Releases gas in the batter, making the cake rise in the oven.
- Milk
- Adds moisture that hydrates the flour and keeps the crumb soft.
- Cocoa powder
- Gives the chocolate batter its flavor and dark color for the marbling.
The step that matters
Creaming the sugar and butter. Beating them until light and fluffy traps air bubbles in the fat, which helps the cake rise and gives it a light texture. Under-creamed butter leads to a dense cake.
