Buttercream is a sweet and creamy frosting made primarily from butter and sugar. It is often used to decorate cakes, cupcakes, and cookies, giving them a rich flavor and smooth texture. The basic recipe can be easily customized by adding flavors like vanilla, chocolate, or fruit, making it a versatile choice for bakers. There are different types of buttercream, such as American, Swiss, and Italian, each with its unique preparation method and texture. American buttercream is the simplest, while Swiss and Italian versions use egg whites for a lighter, silkier finish. This makes buttercream a favorite among both home bakers and professional pastry chefs.
