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):

  1. Hazelnutfits better
  2. Almondfits better
