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 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.
Make the batter
Cream the butter in a bowl.
Gradually beat in the sugar until well combined.
Add the melted chocolate and unbeaten eggs, and beat vigorously for 5 minutes.
Stir in the milk, flour, baking powder, and vanilla extract until smooth.
Bake and finish
Pour the batter into a buttered shallow cake pan.
Bake in a preheated oven at 350°F (175°C) for 30 minutes.
Frost with your choice of frosting.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar, it traps air and adds richness and tender texture.
- Sugar
- Sweetens the cake and helps create a light, tender crumb when creamed with butter.
- Eggs
- Add structure and moisture, and help bind the batter as it bakes.
- Flour
- Provides the main structure that sets as the cake bakes.
- Baking powder
- Releases gas in the batter so the cake rises as it bakes.
- Melted chocolate
- Adds deep chocolate flavor and some richness to the batter.
The step that matters
Beat the eggs into the chocolate mixture for 5 minutes. Vigorous beating incorporates air and combines the eggs evenly with the fat, helping the cake develop a light, uniform structure before the flour is added.
