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.
Make the batter
Cream together the sugar and butter.
Add the sweet milk and mix well.
In a separate bowl, combine the flour, baking powder, and salt.
Gradually add the dry ingredients to the wet mixture.
For the dark part, take a cup of the light batter and mix in grated chocolate.
Assemble and bake
In a greased baking pan, layer the light and dark batters alternately, with the light batter on top.
Bake in a moderate oven at 350°F (175°C) until a toothpick 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, it traps air and adds richness and a tender crumb.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas during baking, helping the cake rise and become light.
- Sugar
- Sweetens the cake and helps create a tender, browned crumb when creamed with butter.
- Grated chocolate
- Adds flavor and color to the dark batter, creating the marbled pattern.
The step that matters
Layering the light and dark batters. Spooning the batters in loose alternating layers, rather than stirring them together, keeps two distinct colors. Mixing them fully would blend the marble into an even brown cake.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
