How to measure powdered sugar
Spoon powdered sugar into the cup without pressing and level the top. If a recipe says "1 cup powdered sugar, sifted", measure first and sift after; "1 cup sifted powdered sugar" means sift first.
Sifted vs unsifted powdered sugar
An unsifted cup weighs 120 g and a sifted cup 100 g, 20 g less. Sifting adds air, so the same cup holds about a sixth less sugar.
Powdered sugar and other sugars
Unsifted powdered sugar weighs 80 g less per cup than granulated sugar, so the two do not swap cup for cup. By weight, 100 g of powdered sugar is ¾ cup + 1½ tbsp.
