Lemon Buttercream

This style of buttercream is smooth and silky, and it holds its shape well, making it ideal for piping or decorating. Although a cake made with this buttercream should be kept in the refrigerator, the buttercream is best enjoyed after it has sat out for 30 minutes to an hour—the frosting softens nicely, making it easy to slice and serve, and it melts easily when you take a bite.
