Learn how to make powdered sugar in minutes using just two pantry staples. This easy kitchen basic is perfect for frostings, glazes, dusting desserts, and baking recipes when you don’t have store-bought confectioners sugar on hand.

Ingredients

  • 2 cups granulated sugar
  • 2 TBSP cornstarch

Instructions

  1. Add the granulated sugar and cornstarch to a high-speed blender.
  2. Blend for about 30–45 seconds, or until the texture becomes light, fluffy, and powder-fine.
  3. Use immediately, or transfer to an airtight container for storage.
  4. If clumps form over time, sift before using for the smoothest consistency.

Notes

Why add cornstarch?
Cornstarch helps prevent clumping and improves the texture so the sugar behaves like store-bought powdered sugar in frostings and glazes.

Blender matters:
A high-powered blender produces the softest texture. Standard blenders may require a little extra blending time.

Storage:
Keep in an airtight container at room temperature for up to several months.

Scaling Tip:
You can easily double or halve this recipe — just maintain the ratio of 1 TBSP cornstarch per 1 cup sugar.
