How to measure it

Cocoa powder is the lightest ingredient on this site at about 85 g a cup, spooned and levelled. It clumps readily, and a cup with compressed lumps can weigh 100 g while a sifted cup falls to 75 g.

Break up visible lumps before measuring, spoon the powder in loosely, and level without tapping the cup. Sift after measuring if the recipe needs smooth batter.

Natural and Dutch-process cocoa weigh about the same per cup. The difference between them is acidity, which affects how the recipe rises, not how it measures.
