If you have granulated sugar on hand, you can make your own powdered sugar in under two minutes.

Difficulty: Easy

Time Required: 15 minutes

Here's How:

  1. Place a cup of granulated sugar in the blender for each cup of powdered sugar needed.
  2. Blend at high speed until the sugar turns to powder.
  3. Use immediately, or store in an air-tight container.


  1. To prevent caking and improve thickening ability (important when making icing), add 1-2 Tablespoons of corn starch for each cup of sugar made.
  2. Sugar may etch your blender pitcher, particularly if it's made of plastic. If this is a concern, use a coffee grinder or spice grinder instead.

What You Need:

  • A blender
  • Measuring cups
  • Measuring spoons
  • Granulated sugar
  • Corn starch (optional)
