Icing sugar is an essential part of most frosting recipes; but, because it's called for in so few other recipes, icing sugar isn't a staple in every cupboard. Luckily, it's easy to turn regular sugar into a powdered-sugar substitute. You can even use an artificial sweetener instead of sugar to create a diabetic-friendly desert.

Skill level:

Things you need

  • 1 cup sugar or sugar substitute
  • 1 tbsp cornflour
  • Blender
  • Spoon

  1. 1

    Measure 1 cup of sugar or sugar substitute and pour it into a blender.

  2. 2

    Measure 1 tbsp of cornflour and add it to a blender.

  3. 3

    Blend the sugar and cornstarch for several minutes.

  4. 4

    Stir the mixture with a spoon.

  5. 5

    Blend the mixture again for several minutes if it is clumpy. The mixture is finished when the sugar is smooth.
