Powdered sugar: How Many Grams in a Cup?
Powdered sugar is the most deceptive ingredient to measure by volume: a sifted cup can weigh half as much as a packed cup! Composed of pulverized sugar and a touch of cornstarch to prevent caking, precise measurement is non-negotiable. Our tool ensures you get the exact amount needed for silky frostings and tender shortcrusts, eliminating the guesswork.

FAQ
- Why can't I substitute powdered sugar for granulated sugar in cakes?
- Powdered sugar contains 3% cornstarch, which absorbs liquid differently, making batters drier. Also, because it's so fine, it doesn't create the necessary air pockets when creamed with butter, resulting in a dense, heavy cake.
- Can I make caramel with powdered sugar?
- No. The cornstarch (anti-caking agent) burns at the high temperatures required for caramelization before the sugar melts properly, leaving you with a burnt, cloudy mess instead of clear amber caramel.
