Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. 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 the oven to 350°F (175°C).
Make the batters
In a bowl, cream together the white sugar and butter until light and fluffy.
Add the sour cream and mix well.
In another bowl, combine the flour and baking soda.
Gradually add the flour mixture to the creamed mixture, mixing until just combined.
In a separate bowl, beat the egg whites until stiff peaks form.
Gently fold the egg whites into the white batter.
For the dark batter, cream together the brown sugar, molasses, and butter.
Add the sour cream and mix well.
Combine the flour and baking soda, then add to the dark batter.
In a separate bowl, beat the egg yolks and mix into the dark batter.
Marble and bake
Pour the dark batter into a greased pan first, then layer the white batter on top.
Swirl the batters together with a knife for a marbled effect.
Bake for 30-40 minutes 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 richness and a tender crumb when creamed with the sugar.
- Egg whites
- Beaten to stiff peaks, they trap air that lifts the light white batter.
- Sour cream
- Adds moisture and mild acidity that keeps the crumb soft.
- Molasses
- Adds dark color, moisture and a deep sweet flavor to the dark batter.
- Baking soda
- Reacts with the acidic sour cream and molasses to make the cake rise.
The step that matters
Gently fold the egg whites into the white batter. Whipped egg whites hold air that gives the cake its lift. Vigorous stirring knocks that air out, leaving a dense, heavy crumb.
