About Powdered Sugar
Powdered sugar (also called confectioners' sugar or icing sugar) is granulated sugar ground to a fine powder with a small amount of cornstarch added. It dissolves instantly, making it ideal for frostings, glazes, and dusting.
For reverse conversion, 1 cup of powdered sugar weighs approximately 120g with Spoon & Level.

Expert Tips
Powdered sugar should be spooned and leveled, never packed. It compacts easily and will give inaccurate measurements if pressed.
Sift powdered sugar before making frosting or glazes to remove any lumps.
Powdered sugar contains about 3% cornstarch to prevent caking - this affects thickening in recipes.
