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.
Prepare the batter
Preheat the oven to 350°F (175°C).
In a large bowl, cream together the butter and sugar.
Add the flour, eggs, milk, and baking powder; mix well.
Take out 1 cup of the batter and mix it with the chocolate and cream.
Layer and bake
Pour the white batter into the bottom of a greased pan.
Drop spoonfuls of the chocolate batter on top to form rings.
Layer with more white batter and repeat until all batter is used.
Bake in the preheated oven 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 and give the cake a tender, rich crumb.
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Flour
- Provides the main structure that holds the cake together as it bakes.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Chocolate
- Gives the darker marbling and a chocolate flavour to part of the batter.
The step that matters
Layering the chocolate batter. Dropping the chocolate batter in spoonfuls and layering it with white batter creates the marbled pattern. Overmixing after layering would blend the colours into an even brown and lose the swirl.
