Is there a difference between powdered sugar and confectioners sugar?

Powdered sugar and confectioners sugar are the same thing. They are a finely ground sugar made from granulated sugar that has been pulverized until it becomes a powder. Powdered sugar is often used in frostings, icings, glazes, and other baking applications where a smooth, fine texture is desired. It is also sometimes used as a sweetener in coffee or tea.
