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.
Powdered sugar is made of granulated sugar which is ground until it becomes its powdery form. Usually, 3% of cornstarch is added to prevent caking.
If a recipe doesn’t specifically call for 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 experience, 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.
If you don’t use it immediately, you should add 1 tablespoon of cornstarch for 1 cup of sugar so you can avoid clumping.
