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

What each ingredient does

All-purpose flour: Provides the structure that holds the brownie together as it bakes.
Granulated sugar: Adds sweetness and helps give the brownie a tender, moist crumb.
Baking powder: Releases gas during baking so the cake rises and becomes light.
Unsweetened cocoa: Supplies the chocolate flavor and deep color of both the cake and the sauce.
Applesauce: Adds moisture in place of some fat, keeping the brownie soft.
Brown sugar: Sweetens the sauce and adds moisture and molasses flavor to the chocolate layer.

The step that matters

Pour the sauce over the batter without stirring it in. The hot, sugary liquid settles beneath the batter as it bakes, forming a sauce layer on the bottom. Stirring it in would blend the layers and lose the distinct sundae-style sauce.
