Measuring powdered sugar by cup and by weight
Powdered sugar, also called confectioners' or icing sugar, is light and fluffy at about 113 g per cup. It is mostly sugar with a little cornstarch to prevent caking, and it compacts in the box, so unsifted sugar can overshoot the weight. For smooth frosting, sift first and then measure or, better, weigh it to get consistent icing thickness.
