What is the differene between confetioneers sugar and granulated sugar?

Confectioners' sugar, also known as powdered sugar or icing sugar, is a finely ground sugar that is about 10% cornstarch to prevent caking. It is typically used in frostings, icings, and other sweet toppings, as it dissolves easily and its smooth texture makes it ideal for creating a glossy finish. Granulated sugar, also known as white sugar or table sugar, is a type of sugar that has larger crystals than confectioners' sugar. It is the most common type of sugar used in baking, as it provides a more structured sweetness and can be used to create different textures, such as crunchiness in cookies.
