Why it works: Cocoa and coffee work together. They rank in the top 3% of all ingredient pairs, and cooks put them together in 91 recipes. Both carry sotolon, which smells curry, maple. The science ↓
Black Magic Cake
Ingredients
Directions
Prepare
Heat oven to 350°F.
Grease and flour two 9-inch round baking pans or one 13x9x2-inch baking pan.
Make and bake the batter
Stir together sugar, flour, cocoa, baking soda, baking powder and salt in large bowl.
Add eggs, buttermilk, coffee, oil and vanilla; beat on medium speed of mixer 2 minutes (batter will be thin).
Pour batter evenly into prepared pans.
Bake 30 to 35 minutes for round pans, 35 to 40 minutes for rectangular pan or until a wooden pick inserted in the center comes out clean.
Cool and finish
Cool 10 minutes; remove from pans to wire racks.
Cool completely.
Frost as desired.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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 as the cake sets in the oven.
- Baking soda
- Reacts with the acidic buttermilk to release gas, helping the cake rise.
- Baking powder
- Adds extra lift so the cake rises evenly in the oven.
- Buttermilk
- Its acidity activates the baking soda and adds tenderness and moisture.
- Vegetable oil
- Keeps the crumb moist and tender after cooling.
- Cocoa
- Provides the chocolate flavor and dark color of the cake.
The step that matters
Beat for 2 minutes and pour the thin batter promptly. Beating develops gluten and air for lift, while the leavening starts reacting as soon as wet and dry ingredients meet, so the batter should go into the pans without delay.
Swap the cocoa
How well each one fits the dish's main ingredients (sugar, flour, egg, buttermilk, coffee, vanilla):
- Hazelnutfits better
- Almondfits better
- Chestnutfits better
- Cocoathe original
Fit is the average pairing score against sugar, flour, egg, buttermilk, coffee, vanilla. Candidates are from the same food group and used in at least 100 recipes.
