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 ↓
Chocolate 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 batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the flour, sweet milk, baking powder, and salt, then mix until well combined.
Take one cup of the batter and mix in the melted chocolate.
Marble and bake
Grease a baking pan and pour the yellow batter into it to about an inch thick.
Drop spoonfuls of the chocolate mixture into the batter to form rings.
Continue layering until all batter 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
- Creamed with sugar to trap air, giving a light, tender crumb and rich flavor.
- Sugar
- Creamed with butter for aeration and adds sweetness and gentle browning.
- Flour
- Forms the cake's structure once its proteins set in the oven.
- Sweet milk
- Adds moisture and hydrates the flour to form the batter.
- Baking powder
- Releases gas during baking so the cake rises and becomes airy.
- Chocolate
- Melted and swirled into part of the batter to create the marbled pattern and chocolate flavor.
The step that matters
Drop the chocolate mixture into the batter. Spoonfuls should be dropped gently rather than stirred in, so the chocolate stays in distinct ribbons. Overmixing blends the two batters into an even brown color and loses the marble effect.
