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 says “a slow 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) and grease a cake pan.
In a large bowl, cream together the butter and sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
In a separate bowl, combine the flour, corn starch, cream of tartar, and baking soda.
Gradually add the dry ingredients to the butter mixture, alternating with the sweet milk.
Stir in the vanilla extract.
Marble and bake
Take out 1 cup of the batter and mix in the grated chocolate.
Drop the chocolate batter alternately with the plain batter into the greased pan.
Swirl gently with a knife to create a marbled effect.
Bake for 30-35 minutes or until a toothpick inserted in the center 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 a light, tender crumb and rich flavor.
- Eggs
- Add structure and richness, helping the batter set around the baked crumb.
- Flour
- Forms the main structure of the cake as its proteins set in the oven.
- Cream of tartar
- Acidic ingredient that reacts with baking soda to help the cake rise.
- Baking soda
- Reacts with the acidic cream of tartar to produce gas that lifts the batter.
- Grated chocolate
- Mixed into part of the batter to create the dark marbled streaks and chocolate flavor.
The step that matters
Swirl gently with a knife. Over-swirling blends the chocolate batter into the plain batter, erasing the marble pattern and turning the cake an even brown. A few slow passes keep the two batters in distinct streaks.
