Measuring ¼ US Cup of Powdered / Confectioners' Sugar in the Kitchen
Measured unsifted spooned at a verified bulk density of 120g per US cup, ¼ US cup of powdered / confectioners' sugar weighs 30 grams (1.06 ounces). Measured using the sifted method (100g/cup), that same ¼ cup holds 25g — a 5g 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.
