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 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 cake
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter.
Add the sweet milk and flour, then mix well.
Fold in the egg whites gently.
Pour the batter into a greased cake pan and bake until a toothpick comes out clean.
Make the filling
For the filling, combine 2 cups sugar, ½ cup sweet milk, ½ cup butter, and ½ cup chocolate or cocoa in a saucepan.
Bring to a boil over medium heat, stirring constantly.
Remove from heat and beat until cool enough to spread.

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 and add tenderness and richness to the crumb.
- Egg whites
- Provide structure and lift when folded in, helping the cake rise and hold its shape.
- Baking powder
- Releases gas in the batter, causing the cake to rise in the oven.
- Flour
- Forms the gluten and starch structure that sets the cake's crumb.
- Sugar
- Sweetens the cake and, creamed with butter, helps give it a tender texture.
- Chocolate or cocoa
- Gives the filling its chocolate flavor and deep color.
The step that matters
Fold in the egg whites gently. Egg whites hold air bubbles that give the cake its lift. Vigorous mixing knocks that air out, leaving a denser, flatter cake.
