2 8oz packages of softened cream cheese
1 stick of unsalted butter
4 cups confectioner's sugar
1 tsp vanilla
1/2 tsp freshly grated lemon zest
In your mixing bowl, put the softened cream cheese and butter. Whip together until smooth. Add the vanilla, and the confectioner's sugar one cup at a time (unless you like a kitchen full of powdered sugar.) Put the mixer on low speed with every addition. Finally put in the lemon zest. If you keep the frosting at room temperature it will spread much easier. Then refrigerate to set up after the cake, or tire or whatever is frosted. Enjoy.
