Powdered sugar, also known as confectioners’ sugar or icing sugar, is a finely ground form of granulated sugar mixed with a small amount of cornstarch to prevent clumping. Its ultra-fine texture makes it ideal for desserts, frostings, glazes, and decorative toppings.
What Is Powdered Sugar?
Powdered sugar is created by grinding white granulated sugar into a soft powder. It typically contains 2–5% cornstarch, which keeps it smooth and prevents moisture absorption. This gives powdered sugar its signature silky texture and instant dissolving ability.
Popular Uses of Powdered Sugar
Powdered sugar is one of the most versatile sweeteners in baking. Common uses include:
- Cake frostings & buttercream
- Donut and pastry coatings
- Glazes for cookies and breads
- Whipped cream sweetener
- Dusting on brownies, waffles, pancakes, and French toast

Because it dissolves quickly, powdered sugar is perfect for recipes requiring smooth textures and elegant finishes.
