How do you make icing powder?

You can't really make icing powder from scratch at home. Icing powder, also known as powdered sugar, is simply granulated sugar that has been finely ground and often mixed with a small amount of cornstarch. The cornstarch helps to prevent the powdered sugar from clumping.

However, you can make your own powdered sugar using a blender or food processor. Here's how:

Materials:

* 1 cup granulated sugar

* 1 tablespoon cornstarch (optional)

Instructions:

1. Combine: Combine the granulated sugar and cornstarch (if using) in a blender or food processor.

2. Blend: Blend until the sugar is finely ground, like powder.

3. Sift: For a smoother texture, sift the powdered sugar through a fine-mesh sieve.

Important Notes:

* This method produces a powdered sugar that is similar to the store-bought variety, but it may not be as fine.

* You can adjust the amount of cornstarch to your liking. More cornstarch will result in a less sweet and more "fluffy" powdered sugar.

If you're looking for a specific type of icing powder, like royal icing powder, you'll need to purchase it pre-made.
