How to make icing sugar?

To make homemade powdered sugar you need to finely grind down sugar and blend together with cornstarch (corn flour).

You will need a blender or if you have an electric spice grinder this will work well too.

Also it helps to have a spatula to scrap down the blender to ensure everything is incorporated during the mixing process.

You can use any sugar which you have in the house, this does work with brown sugar or for a healthy version of powdered sugar use coconut sugar.
