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

What each ingredient does

Powdered sugar
Provides sweetness and a smooth, light body to the filling.
Butter
Adds fat for richness and a creamy, spreadable texture.
Warm coffee
Deepens and rounds out the chocolate flavor with a subtle roasted aroma.
Cocoa or chocolate
Supplies the main chocolate flavor and dark color.

The step that matters

Stir in the cocoa or chocolate until well combined. Cocoa powder tends to clump when added to fat and sugar. Thorough mixing disperses it evenly, so the flavor is consistent and the filling is smooth rather than gritty.
