How to Make Homemade Powdered Sugar Recipe
Introduction
Making powdered sugar at home is quick and easy, requiring just granulated sugar and, optionally, cornstarch. This simple recipe lets you create fresh, fine sugar perfect for frosting, dusting desserts, or any baking need.

Ingredients
- 2 cups granulated sugar
- 2 tablespoons cornstarch (optional)
Instructions
- Step 1: Pour the granulated sugar into a blender and process for about 30 seconds until it turns into a fine powder.
- Step 2: If using a food processor, it may take 3 to 5 minutes to achieve a fine powder. Stop occasionally to stir the sugar from the bottom for even grinding.
- Step 3: When using a coffee grinder, process the sugar in small batches, about half a cup at a time, since it cannot hold 2 cups at once.
- Step 4: Use the powdered sugar immediately, or transfer it to a tightly sealed container for storage.
Tips & Variations
- Add 2 tablespoons of cornstarch while blending to prevent clumping and improve texture, especially if you plan to store the powdered sugar.
- If you prefer a finer powder, blend for longer, but be careful not to overheat the blender motor.
- Use this homemade powdered sugar as a fresh alternative to store-bought for superior flavor in frostings and dustings.
Storage
Store homemade powdered sugar in an airtight container at room temperature to keep it dry and free from clumps. It can be stored this way for several weeks. Before using stored powdered sugar, sift it to remove any lumps. There is no need to reheat; simply use as you would store-bought powdered sugar.

FAQs
Can I make powdered sugar without a blender?
Yes, a food processor or a coffee grinder can also be used to make powdered sugar. Just be sure to work in small batches if using a coffee grinder, as it has limited capacity.
Why use cornstarch in homemade powdered sugar?
Cornstarch helps absorb moisture and prevents the powdered sugar from clumping, especially if you plan to store it for some time. It also helps improve the texture when using the sugar in frostings and icings.
