Icing sugar is also known as confectioners sugar or powdered sugar. It is made by grinding granulated sugar into a fine powder. It usually contains cornflower to keep it from clumping together, making it unsuitable for people with gluten intolerance.
As its name suggests, icing sugar is mostly used in decoration rather than baking. As it is the finest sugar available it dissolves almost instantly into mixtures. It is perfect for buttercream, cream cheese icing and royal icing or simply dusting over cakes or cookies.
1 cup of icing sugar is equal to 110 grams.
