The difference between powdered sugar and frosting:

Sugar powder is made by grinding white sugar into powder and mixing corn starch with ground sugar. It can be used in the process of making various snacks and cakes, and can also be used as surface decoration, but it is recommended to choose moisture-proof powdered sugar or frosting as surface decoration. Frosting is obtained by treating powdered sugar.

Frosting is a sweet decoration for cakes and other baked goods. There are many kinds of frosting, such as protein frosting, which is made of egg white and lemon juice and is wet. If pigment is added, it is colored icing, which has a certain viscosity and can be used for the modeling of baked goods. In short, you can use powdered sugar instead of frosted screen to decorate the surface, but you can't use frosted instead of powdered sugar.

Powdered sugar, as can be easily seen from the name, refers to powdered sugar. Sugar powder is a replica of sucrose. It is pure white powder and tastes the same as sucrose. Sugar powder is very fine, easy to mix with batter, has a good emulsifying effect on oil and can produce a very uniform structure. So when making cookies, using some powdered sugar can make cookies look more beautiful and keep the patterns clear.

Powdered sugar is very useful. It can be used to make cookies, cakes and so on. More often, it is used to decorate cakes. Screen a layer of powdered sugar on the surface of the finished cake, and the appearance will become much more beautiful. Often used for heavy oil cake or cake decoration. It is also used to make icing and cream fillings, such as custard when making gingerbread houses.

In order to prevent caking due to moisture during storage, about 3% starch is usually mixed into powdered sugar. Sugar powder is divided into many grades according to the particle size. "10X" powdered sugar is the best. Generally, 6X powdered sugar is used more.
