The 3 stages of making homemade powdered sugar

How to Make Powdered Sugar Without Cornstarch

Simply place your sugar of choice in a food processor, high-powered blender, coffee grinder, or magic bullet. Process it until it’s fine and fluffy, which should take about three minutes depending on your device.

Pro Tips/Recipe Notes

  • Store homemade powdered sugar in an air-tight container. I prefer a mason jar.
  • If you’re using the confectioner’s sugar the same day, you do not need to add anything to the mixture. If you want to store it for longer than a week, adding 1 tbsp of cornstarch or arrowroot powder will help keep things clump-free.
  • If you are using this sugar for frosting, I highly recommend making it an hour or so before you need to use it. The sugar will become warm during the processing, thus makes it harder for the frosting to set.

How to Make Powdered Sugar

Prep Time3 mins
Total Time3 mins
Learn how to make icing sugar in your own kitchen. Just one ingredient and three minutes are all you need to make it yourself.


  • sugar {as much as needed}


  • Place the desired amount of sugar in a food processor, high-powered blender, or Magic Bullet.
  • Process for 1-3 minutes, or until it has reached your desired consistency. {Do stay near the blender while it is processing.}
  • Finished powdered sugar should be fine, and easy to sift.


If using a blender or food processor, I find it best to place a damp towel over the top to catch any escaping powdered sugar.
If using more than 2 cups of sugar, separate into multiple batches for processing.
Stay in the same room with the blender while it is processing.
