Why it works: Milk and butter 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 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.
Make the filling
Prepare the filling by combining 1 cup chocolate, ½ cup milk, 1 cup sugar, and 1 egg yolk. Let it cool.
Make the batter
In a large bowl, cream together 2 cups brown sugar and 1 cup butter.
Add 1 cup milk and 6 eggs to the mixture, then mix well.
Gradually add 1½ cups flour and 1 teaspoon baking powder until the batter is stiff.
Set aside the whites of 3 eggs for frosting.
Bake and frost
Pour the batter into a greased cake pan and bake at 350°F (175°C) until a toothpick comes out clean.
Once cooled, frost the cake with chocolate frosting.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure and richness as the cake sets in the oven.
- Flour
- Provides the structure that holds the cake's crumb once baked.
- Baking powder
- Releases gas in the oven so the batter rises and turns light.
- Butter
- Adds fat and tenderness, and carries flavor through the crumb.
- Brown sugar
- Adds sweetness and moisture, and helps the cake brown and stay soft.
- Chocolate
- Gives the cake its main chocolate flavor and deep color.
The step that matters
Gradually add the flour and baking powder until the batter is stiff. Adding flour gradually keeps the batter smooth so lumps do not form. Overmixing once flour is in develops gluten, which can make the cake tough and dense rather than tender.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
