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 or Spiced 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 white batter
Preheat the oven to 350°F (175°C).
In a bowl, cream together the white sugar and butter until light and fluffy.
Add the sour cream or buttermilk and mix well.
In another bowl, beat the egg whites until stiff peaks form, then fold into the batter.
Sift together the flour and baking soda, then gradually add to the batter, mixing until just combined.
Make the dark batter
In a separate bowl, combine the brown sugar, molasses, sour cream, butter, baking soda, and egg yolks.
Mix in the flour and spices until smooth.
Bake and finish
Grease a cake pan and layer the white and dark batters alternately until the pan is full.
Bake for about 30-40 minutes or until a toothpick inserted in the center comes out clean.
Let cool before icing and decorating with chocolate drops.

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, rich crumb.
- Eggs
- Egg whites add lift and structure, while yolks add richness and help bind the batter.
- Baking soda
- Reacts with the acidic sour cream and molasses to produce gas, helping the cake rise.
- Molasses
- Adds dark color, moisture, and a deep, slightly bitter sweetness to the dark batter.
- Sour cream
- Adds acidity and moisture, tenderizing the crumb and activating the baking soda.
- Flour
- Provides the structure that holds the cake together as it bakes.
The step that matters
Folding in the beaten egg whites. Stiff whites hold the air that lifts the batter. Folding gently with a spatula keeps that air in; stirring hard deflates it and leaves a dense 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.
