1 cup of cocoa powder in grams

One level US cup (240 ml) of cocoa powder weighs about 100 grams. That makes ½ cup ≈ 50 g, ⅓ cup ≈ 33 g and ¼ cup ≈ 25 g. These are scoop-and-level averages — packing the cup can add up to 20%, which is why bakers swear by a scale. More ingredients in the full cups-to-grams converter.
