Substitute for Powdered Sugar
Make powdered sugar at home or find perfect substitutes for frostings and dusting. Quick and easy solutions.
Quick Answer
The best substitutes for powdered sugar are: Granulated Sugar + Cornstarch (Homemade), Granulated Sugar (Blended Only), Coconut Sugar (Blended). Each works differently depending on your recipe needs.
Powdered sugar (confectioner’s sugar) is essential for smooth frostings and delicate dusting. Making your own ensures freshness and lets you control ingredients.
Why Powdered Sugar Matters
The ultra-fine texture of powdered sugar dissolves instantly, creating smooth frostings and glazes. Its cornstarch content (about 3%) prevents clumping and helps maintain texture.
Making Perfect Homemade Powdered Sugar
Use a high-speed blender or food processor for finest results. Let the machine rest between batches to prevent overheating. Sift the final product for ultimate smoothness in frostings.
