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

What each ingredient does

Flour: Provides the main structure that holds the cake together as it bakes.
Egg whites: Add structure and lift, helping the batter set as it bakes.
Cocoa: Gives the cake its chocolate flavor and dark color.
Cornstarch (in the method): Softens the crumb and adds tenderness to the cake.
Sugar: Sweetens the cake and helps keep it moist and tender.
Corn syrup: Adds sweetness and moisture, helping the cake stay soft.

The step that matters

Gradually stir the wet mixture into the dry ingredients until smooth. Fat-free batters have little fat to coat the flour, so overmixing develops gluten and can make the cake tough. Stir just until smooth and no dry flour remains.
