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 tender, rich crumb.
Flour: Provides the structure that holds the cake together as it bakes.
Egg whites: Add structure and lift to the white batter, keeping it light.
Egg yolks: Add richness and moisture to the dark batter and help bind it.
Baking powder: Releases gas during baking, helping the cake rise and become light.
Molasses: Adds moisture, deep sweetness, and color to the dark batter.

The step that matters

Layering the white and dark batter. Pouring the two batters in loose, uneven layers keeps them separate enough to form the marbled pattern. Over-stirring them together blends the colors into a uniform brown cake.
