How to Make Powdered Sugar

We all know the pain of making a batch of cinnamon rolls and turning around to find you’re out of powdered sugar. Without extra time to run to the store, missing out on this key ingredient could spill disaster for many recipes. However, there’s a solution if you have white sugar and a food processor or blender around. Powdered sugar is white cane sugar that has been pulverized to a fine powder. You can achieve the same result with a bit of cornstarch and just a few minutes of time.

Servings: 16 servings
Yield: 2 cups


  • 2 cups granulated white sugar
  • 2 tablespoons cornstarch


  1. Combine the sugar and cornstarch: Combine the sugar and cornstarch in a blender jar or bowl of a food processor.
  2. Pulverize the sugar: Turn the machine on to high speed and run 3 to 5 minutes. The time will depend on your blender or food processor; some high speed blenders will take as few as 3 minutes. Stop the machine every few minutes to scrape down the sides to make sure all the sugar gets evenly pulverized.
  3. Check the texture of the sugar: The sugar is done when it feels fine and powdery when you rub it between your fingers; if it’s still gritty, keep processing.
  4. Use right away or store for later: The powdered sugar may be hot from the friction of the machine. If it is, let it cool before putting in an airtight container or zip top bag. Like regular powdered sugar, it will keep indefinitely.
