How many cups of powdered sugar are in a pound?

The number of cups in a pound of powdered sugar depends on whether it is sifted or unsifted:

1. Unsifted powdered sugar:
   • 1 pound = approximately 3 ½ to 4 cups.
2. Sifted powdered sugar:
   • 1 pound = approximately 4 ½ cups.

For accurate measurements, always check the recipe requirements (sifted or unsifted) and consider weighing the powdered sugar if precision is crucial.
