How to make sugar powder

Food

You use a lot of sugar powder when you bake cookies or bread.

I bought it at the mart every time, so I don't use it unless I bake it, so I throw it away because it's too old, and if I try to use it, it's quite troublesome to order it at a large mart. I want to make it a little at home when I need it. How can I make it?
