This homemade powdered sugar recipe is SO easy - you'll never get the store bought kind again! Use it in any recipe that calls for powdered sugar, icing sugar, or confectioner's sugar. Find some of my favorites in the post above.
Place the sugar and cornstarch in a high speed blender and blend for 30 seconds or until fluffy.
Store in an airtight container. If the powdered sugar gets lumpy, sift before using.
