I use this cream cheese frosting as a crumb coat under regular Cream Cheese Frosting. The addition of shortening creates a frosting that hardens just enough to allow the finishing layer of Cream Cheese frosting, or any buttercream recipe of your choices, to spread easily. This recipe makes enough to crumb coat an 8 or 9-inch cake, 2-6 layers high. Tip: Any leftover Crusting Cream Cheese Frosting can be stirred into your regular cream cheese frosting if desired for frosting the cake.
