What each ingredient does

Sweet cooking chocolate: Provides the rich chocolate flavor and fat that gives the brownies their dense texture.
Butter: Adds fat for a tender, moist crumb and helps carry the chocolate flavor.
Eggs: Add structure and binding as they set, along with moisture and richness.
Sugar: Adds sweetness and helps give the brownies a tender, moist texture.
Flour: Provides the structure that holds the brownies together as they bake.
Baking powder: Releases gas in the oven to give the brownies a light lift.
