This buttercream frosting can be used for cakes, cookies, and pastries. It can be modified with colors, flavorings, and the use of liqueurs. You will find it to be versatile, providing a gorgeous and delicious base for many baked goods. I use this recipe to frost my cookies and cakes. This recipe will easily frost 24 sugar cookies. It will also frost a four-layer cake between layers and on the outside providing full coverage on the top and sides.
