1 minute
Total Time:1 minute

Equipment

  • 1 hand blender, spice grinder, or food processor
  • 1 fine mesh strainer optional
  • 1 airtight container optional, for storage

Ingredients

  • 1 cup granulated sugar or however much you need for your recipe
  • 1 tbsp cornstarch optional, for storage purposes only

Instructions

  • Add the granulated sugar to a dry, high-speed blender or food processor.
  • Blend for 30 seconds to 1 minute, or until the sugar becomes very fine and fluffy.
  • Optional: Add 1 tablespoon of cornstarch per cup of granulated sugar, and pulse to combine, especially if you're storing it for later.
  • Let the dust settle before opening the lid, then check the texture.
  • If needed, sift through a fine mesh strainer for extra smoothness.
  • Use the powdered sugar immediately or store it in an airtight container.

Notes

  • Blender tip: Make sure your blender or processor is completely dry before use.
  • Storage: Store in a sealed container in a cool, dry place for up to several months.
  • Cornstarch: This helps prevent clumping, especially if you're not using the sugar right away.
