Powdered Sugar Substitute | How to Make Powdered Sugar

You can still make things like buttercream frosting without powdered cane sugar, just make this homemade unrefined powdered sugar!

Ingredients

  • 1 cup low-carb sweetener
  • 1 tablespoon cornstarch (optional - see alternatives above)

Instructions

    Cup of Yum
  1. Place the sweetener and either cornstarch or arrowroot into your blender or food processor. (I highly recommend the Vitamix!).
  2. Blend on high continuously until the mixture is of uniform powdered consistency. In a high-powered blender like the Vitamix this will take only about 30 seconds.
  3. Keep the lid on the blender until the powder settles (or you might have powdered-sugar coated cabinets, depending on how much of a powdered-sugar cloud gets kicked up by your blender!)
  4. Store in a cool, dry place.

Notes

  • Arrowroot: You can substitute organic arrowroot or tapioca starch for cornstarch. If you are on a keto diet or the Trim Healthy Mama eating plan, you can omit.
  • Starch Ingredient Information: The cornstarch / other starch portion of the recipe helps the powdered sugar not to cake. It's not necessary but preferable.
