Making Homemade Powdered Sugar

Sharing is caring!

Did you know that powdered sugar, also known as confectioner’s sugar or icing sugar, is just blended sugar?  I know right – mind blowing! Okay, maybe not to you but it was to me. I mean it makes sense, but who knew????

I can’t tell you how many times I have started making a recipe to find that I am out of powdered sugar. I mean I am sure it has happened to all cooks at one point. There is nothing worse than reaching into the pantry for the powdered sugar to find you are out. If never fails that at some point, especially during Christmas, when I am late night baking, that I realize I am out of powdered sugar. Late night baking is something I do on a regular basis mainly because that is when all the crazy slows down. I mean with grandbabies in the house there is a load of crazy at all times. And who wants to run out to the grocery store at midnight? Not me. With that in mind, I realized you could make your own powdered sugar. Follow the steps below to make your own powdered sugar.

The pictures below are when I added the sugar and powdered sugar to the food processor and then the end results.

This recipe is going to show you how to make homemade powdered sugar (also know as confectioner’s sugar). Prefect when you go to make my Oreo Dirt Box Cups and your realize you are out of powdered sugar!


  • 2 cups of white sugar

  • 2 tablespoons of cornstarch


  • You need a small powerful blender, Nutribullet, Vitamix, food processor or spice grinder. I had the best success in the Nutribullet.
  • Pour sugar and cornstarch into your blender. The cornstarch is important as it keeps the sugar dry.
  • Blend on high until sugar is fine and fluffy (about 2-4 minutes depending on the processor that you use). Stop and stir from the bottom of your container to make sure it is all getting blended.  
  • After a couple of minutes run it through your fingers to see if it feels gritty. If it feels gritty, keep blending. You might still feel a little texture at the end but that is fine. If you can’t get it really fine, you might need to try a stronger blender. 

  • Store in an airtight container for later use.
