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.
Make the light batter
Preheat the oven to 350°F (175°C).
In a bowl, cream together 1 ½ cups sugar and ½ cup butter until light and fluffy.
Add ½ cup sweet milk and mix well.
Stir in 2 teaspoons baking powder and 2 ½ cups flour.
Fold in the 4 egg whites until just combined.
Make the dark batter
In another bowl, mix 1 cup brown sugar, ½ cup molasses, and ½ cup butter.
Add ½ cup sour milk, ½ teaspoon baking soda, and 1 teaspoon cream of tartar.
Stir in 2 ½ cups flour and the 4 egg yolks.
Marble and bake
Combine both mixtures by alternating spoonfuls in a greased cake pan.
Swirl the batter gently with a knife to create a marbled effect.
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
- Butter
- Creams with sugar to trap air, giving the cake a tender, fine crumb.
- Egg whites
- Whipped into the light batter to add lift and a light, airy structure.
- Egg yolks
- Add richness and moisture to the dark batter and help bind it.
- Molasses
- Colors the dark batter and adds depth of sweetness and moisture.
- Baking powder
- Releases gas in the light batter, helping the cake rise.
- Flour
- Provides the main structure that holds the cake together as it sets.
The step that matters
Swirl the batter gently with a knife. Over-swirling mixes the light and dark batters into an even brown color, losing the marble pattern. A few gentle passes keep the two batters distinct while still blending them enough to bake evenly.
“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.
