Measuring ¾ US Cup of Powdered / Confectioners' Sugar in the Kitchen
Measured unsifted spooned at a verified bulk density of 120g per US cup, ¾ US cup of powdered / confectioners' sugar weighs 90 grams (3.17 ounces). Measured using the sifted method (100g/cup), that same ¾ cup holds 75g — a 15g difference in your mixing bowl.
Spoon gently into the measuring cup and level flat. If your recipe calls for sifted powdered sugar, measure after sifting (100g/cup) or weigh directly.
