Ingredients

  • 1 cup granulated sugar (makes 2 cups of powdered sugar)
  • 1 tbsp cornstarch optional- see note below

Instructions

  • Measure out half the amount of powdered sugar you’ll be needing. (Half a cup of regular sugar will produce one cup of powdered sugar).
  • Pour sugar into a high-powered blender. If using, add cornstarch.
  • Blend on high until sugar is fine and fluffy (about 30 seconds).
  • Optional: sift before use for clump free, extra fluffy sugar.

Notes

TIP: Make a larger batch of sugar and store in an air-tight container in the pantry for later use.
Note RE Preservatives:
Most store-bought powdered sugars contain a bit of cornstarch to keep the sugar dry. Though useful, cornstarch isn’t the healthiest addition to a recipe. I love that, by making my own sugar, I can closely control what gets added to my food.
If I’m whipping up a quick batch to make frosting or dust on as a topping, I skip the cornstarch. But, if I’m making a larger batch to store in the pantry, I do add a bit of my own preservative. Arrowroot powder, tapioca flour or organic cornstarch are all great options! Add one tablespoon of cornstarch (or your preferred alternative) for every one cup of sugar.
