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 ↓
Marbled Chocolate Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the eggs and milk, mixing well.
Sift in the flour and baking powder, and combine until smooth.
Take out 1 cup of the batter and mix it with the dissolved chocolate.
Layer and bake
In a greased pan, pour a layer of the white batter.
Drop spoonfuls of the chocolate batter on top to form rings.
Repeat layering with the remaining batters until all is used.
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
- Adds fat and richness, and creaming it with sugar traps air for a tender crumb.
- Sugar
- Sweetens the cake and helps create a light, fluffy texture when creamed.
- Eggs
- Provide structure as they set, and add richness and moisture to the batter.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Baking powder
- Releases gas in the batter to help the cake rise.
- Chocolate
- Gives the darker batter its flavor and the marbled pattern.
The step that matters
Layering the batters. Pouring the batters gently keeps the layers distinct; stirring or heavy pouring blends the chocolate into the white batter and blurs the marbling.
