Measuring 100 mL of Powdered / Confectioners' Sugar in the Kitchen
Measured unsifted spooned at a verified bulk density of 120g per US cup, 100 mL of powdered / confectioners' sugar weighs 50.7 grams (1.79 ounces). Measured using the sifted method (100g/cup), that same 100 mL holds 42.3g — a 8.5g 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.
