Making your own powdered sugar is one of the simplest and most cost‑effective kitchen tricks — perfect for frugal bakers and anyone who loves homemade solutions. You can whip up soft, fluffy powdered sugar in under a minute using pantry staples you already have.
Ingredients
-
1 cup granulated sugar
-
1 tablespoon cornstarch (optional, prevents clumping)
Equipment
-
High‑speed blender, food processor, or spice grinder
-
Fine‑mesh sieve (optional for extra smoothness)
-
Airtight container for storage
Instructions
-
Add sugar and cornstarch to blender. Combine both ingredients and secure the lid tightly.
-
Blend until fine and fluffy. Process on high speed for 30 seconds to 1 minute. Stop occasionally to stir and check texture.
-
Check consistency. Rub a pinch between your fingers — if it feels gritty, blend a little longer.
-
Let it settle. Wait a few seconds before opening the lid to avoid a sugar cloud.
-
Sift and store. For silky frosting or glaze, sift the sugar before use. Store in an airtight container in a cool, dry place.
Tips for Perfect Powdered Sugar
-
Use a powerful blender for the smoothest texture.
-
Skip cornstarch if you plan to use it immediately.
-
Add flavor twists: try blending with a bit of vanilla bean or cinnamon for custom powdered sugar.
-
Ratio note: 1 cup granulated sugar yields about 2 cups powdered sugar.
