Buttercream frosting is a sweet and creamy icing made primarily from butter and powdered sugar. It is often flavored with vanilla, chocolate, or other extracts, making it a versatile choice for various desserts. This frosting is popular for decorating cakes, cupcakes, and cookies due to its smooth texture and ability to hold shapes. There are different types of buttercream, including American buttercream, which is the simplest and quickest to make, and Swiss meringue buttercream, which is lighter and silkier. Buttercream can be easily colored with food dyes, allowing for creative designs and vibrant decorations on baked goods.
