FAQ

How many cups is 1 ounce of powdered sugar?

1 ounce of powdered sugar is about 0.24 cups, based on a standard weight of 120 grams per US cup.

Why do gram weights for powdered sugar vary between recipes?

Volume measurements depend on how the ingredient is packed. Spooned-and-leveled powdered sugar weighs less than scooped. Our values use standard baking averages, so brands and techniques may differ by a few percent.

Is it better to measure powdered sugar by weight or volume?

Weight. A kitchen scale removes packing errors entirely, which is why professional recipes list grams. Use this table to convert older volume-based recipes.
