Powdered Sugar Recipe
With the right equipment on hand, you're ready to make DIY powdered sugar! The process only takes about 5 minutes.
- 1 cup granulated sugar
- 1 tablespoon cornstarch (optional) The cornstarch is optional, but it helps the powdered sugar stay smooth and clump-free when stored.
Add the granulated sugar to a food processor, blender, coffee grinder or mortar.
Process on high speed until it becomes a fine, fluffy powder. This takes 1-2 minutes in a food processor or blender, or 5+ minutes with a mortar and pestle.
If using cornstarch, pulse it in until evenly distributed in the sugar.
Sift the powdered sugar through a fine mesh sieve to remove any clumps.
Store in an airtight container. Keeps indefinitely!
