Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and 81,283 recipes mention both. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Devil's Food Cake
Ingredients
Directions
Make the chocolate mixture
Melt the chocolate. Add it to the hot milk with the sugar and cook to a smooth paste. Then add the egg, beaten without separating the white and yolk, and set aside to cool.
Make the batter
Beat one-half cup of butter and one cup of sugar together.
Add the yolks of two eggs.
Alternately add one-half cup of milk and two and one-fourth cups of flour that has two rounding teaspoonfuls of baking powder and a little salt sifted with it.
Add the well-beaten whites, the cold chocolate mixture, and one tablespoonful of warm water. A little more flour may be needed.
Bake and finish
Bake in two layers.
Fill the layers and cover the top with boiled frosting.

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 add tenderness and richness to the crumb.
- Eggs
- Add structure and richness; whites are beaten in for lift and lightness.
- Flour
- Forms the structure of the cake crumb as it sets in the oven.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Chocolate (in the method)
- Gives the cake its dark color and chocolate flavor.
The step that matters
Adding the well-beaten whites. Whites hold air that gives the cake lift. Folding them in gently with the cold chocolate mixture keeps the air from deflating, so the layers rise evenly and stay light.
“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.
