Powdered sugar, also known as confectioners' sugar or icing sugar, is a finely ground form of sugar that is commonly used in baking and dessert-making. It is made by grinding granulated sugar into a powder and often includes a small amount of cornstarch to prevent clumping. This sugar dissolves quickly, making it ideal for frostings, glazes, and dusting over desserts. Due to its fine texture, powdered sugar is often used to create smooth and creamy mixtures. It is a staple ingredient in many recipes, including buttercream frosting, mousses, and whipped cream. Its sweet flavor and versatility make it a favorite among bakers and pastry chefs.
