Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butter
Creamed with sugar to trap air and give the cake a tender, rich crumb.
Brown sugar
Adds sweetness and moisture, and its molasses gives a deeper flavor.
Eggs
Add structure and richness, and help bind the batter.
Grated chocolate
Provides chocolate flavor and color, and adds richness to the batter.
Flour
Forms the main structure of the cake as it sets in the oven.
Baking soda
Reacts with the acidic and moist batter to produce gas that helps the cake rise.

The step that matters

Beating the eggs until very light. Beaten eggs trap air that expands in the oven and lightens the batter. Under-beaten eggs can leave the cake dense and heavy.
