How Many Cups Are in a Pound of Powdered Sugar? – When measuring powdered sugar, four cups will roughly equal one pound. However, this is only a relatively precise measurement if the sugar is not crushed into the cup, but rather poured carefully. After measuring the correct amount of powdered sugar, you should always whisk it to break up any clumps.
How many cups of powdered sugar does one pound equal?
Powdered sugar directly from the box or plastic bag weighs 4 1/2 ounces per cup; therefore, a 1-pound box (or 16 ounces) provides approximately 3 1/2 cups of powdered sugar.
