What is "powdered sugar"?

Powdered sugar, also known as confectioner's sugar or icing sugar, is a finely ground sugar that has been processed into a powdery consistency. It is commonly used in baking, dessert making, and confectionery to create smooth, creamy icings, frostings, and glazes. Powdered sugar dissolves easily and combines smoothly with other ingredients, resulting in a velvety texture ideal for decorating cakes, cookies, and pastries. It is also commonly dusted over desserts like donuts, cookies, and fruit to add a sweet finishing touch.
