Ingredient questions

Powdered sugar FAQ.

How many grams are in a cup of powdered sugar?

This page uses 113g per US cup as the PantryGauge reference. The named ingredient and measurement basis matter, so do not reuse the figure for a different product state.

How should powdered sugar be measured?

Use the unsifted reference: spoon it into the cup and level without packing. When a recipe gives grams, weighing remains the more repeatable option.

Can I use this powdered sugar conversion for another type?

Use caution. Sifting changes the volume, so a recipe that specifically says sifted should be treated as a different measuring state. Check the recipe's exact ingredient and, when available, its product-specific weight reference.
