If you want to make a recipe with powdered sugar and you are out of it, don’t give up!  You can easily make yours in 2 minutes!  You just need granulated sugar and in some cases a little bit cornstarch.

Homemade Powdered Sugar

Powdered sugar is made of granulated sugar which is ground until it becomes its powdery form. Usually 3% cornstarch is added to prevent caking.

If a recipe doesn’t specifically call for a cornstarch added powdered sugar or if you use it immediately, you can make yours only with granulated sugar.

How do I make Homemade Powdered Sugar?

I usually use my small food processor because I make my powdered sugar in small quantities.

First I put 100 to 200 grams (1 to 2 cups) sugar to the bowl.  Then I pulse granulated sugar at 2-3 seconds intervals for 1-2 minutes until it is in powdery form.

I don’t rush to open the lid.   In my first experince, after I come up with powder clouds,  I started to wait for 30 seconds or so until the sugar settles.

Finally, I  sift it so I am sure that it is totally ground and free of lumps.
