How many cups of powdered sugar are in a pound?

Answer:

Number of Cups

There are about 3 1/2 to 4 cups of powdered sugar in a pound. But this depends on the sugar's humidity, moisture, and density. Sifting adds air and increases volume, therefore sifted powdered sugar would be less dense than unsifted.

3 1/2 cups unsifted powdered sugar = 1 pound

4 cups sifted powdered sugar = 1 pound
