Buttercream is the kind of frosting you are most likely to find at the
supermarket and is great for frosting cakes and cupcakes. It is made up
of butter or margarine mixed with powered sugar, although eggs and milk
can also be added to change its thickness and texture. Light, creamy,
and easy to work with, buttercream frosting is used to fill and
decorate. Buttercream has a smooth soft consistency and melts easily,
but hardens when refrigerated and will only keep a few days.
