How to Make Powdered Sugar

When making your own powdered sugar, select a high-quality granulated sugar for the best results. Avoid using brown sugar or any other variety with a coarse texture, as it may not yield the desired fine consistency of powdered sugar.

Homemade powdered sugar is often more cost-effective than buying pre-packaged versions, especially if you need it in small quantities. You can buy granulated sugar in bulk, and the cornstarch, if used, is a small addition, which saves money in the long run.

When you make your own powdered sugar, you have complete control over the ingredients used. You can choose high-quality granulated sugar and, if desired, organic or non-GMO options. Additionally, you can omit cornstarch or use alternatives like tapioca starch for those with dietary restrictions.
