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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat oven to 350°F (175°C).
Make the dark batter
In a bowl, cream together brown sugar and ½ cup butter.
Add sour milk, molasses, 2½ cups flour, and egg yolks. Mix well.
Make the white batter
In another bowl, cream together white sugar and ½ cup butter.
Add milk, 2½ cups flour, and egg whites. Mix well.
Assemble and bake
Add 1 teaspoon baking powder to each cup of flour.
In a greased pan, alternate layers of dark and white batter.
Bake for 30-40 minutes or 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
- All-purpose flour
- Provides the main structure that holds the cake's crumb together as it bakes.
- Eggs
- Egg yolks and whites add richness and set the batter into a firm, tender structure.
- Butter
- Adds fat for a tender crumb and rich flavor, and is creamed with sugar to trap air.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Brown sugar
- Adds sweetness, moisture, and a deeper caramel-like flavor to the dark batter.
- Molasses
- Adds moisture, dark color, and a robust flavor that distinguishes the dark batter.
The step that matters
Alternate layers of dark and white batter. Pour the two batters gently in separate layers so they stay distinct; vigorous spreading or mixing blends them and erases the marbled pattern.
