Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. 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.
Prepare the batter
Preheat the oven to 350°F (175°C).
In a bowl, cream together the sugar and butter until light and fluffy.
Add the milk and eggs, mixing well.
In a separate bowl, combine the cream of tartar, baking soda, and flour.
Gradually add the dry ingredients to the wet mixture, stirring until smooth.
Marble and bake
Dissolve the chocolate in a little water and mix with ½ cup sugar and 2 tablespoons of the cake batter.
In a greased cake pan, pour a layer of the white batter, then streak the dark chocolate mixture through it, alternating layers.
Bake for about 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
- Creams with sugar to trap air, giving the cake a light, tender crumb.
- Eggs
- Add structure and richness, helping the batter set as it bakes.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Baking soda
- Reacts with the acid in the batter to produce gas that helps the cake rise.
- Chocolate
- Provides the dark marbling and deep chocolate flavour in the streaked layers.
The step that matters
Streaking the chocolate mixture through the batter. Too much swirling blends the dark and light batters into a muddy color instead of distinct streaks. Light, few passes keep the marble pattern clear and the flavors separate.
