Can You Use Cornstarch For Powdered Sugar?
No, cornstarch cannot be used as a substitute for powdered sugar. Powdered sugar consists of finely ground granulated sugar that is blended with a small amount of cornstarch to prevent caking. Cornstarch has a different texture and does not have the sweetness that powdered sugar has. If you need powdered sugar and do not have it on hand, you can make your own by blending granulated sugar with a small amount of cornstarch in a blender or food processor.
