2 stickes of softened butter
1 softened 8 oz package cream cheese
1 tsp vanilla
4 1/2 cups sifted powdered sugar.
Cream butter and cream cheese together in the bowl of a mixer until creamy. Add vanilla and mix. Add the sugar one cup at a time to the bowl of your mixer. Mixing until the powdered sugar is fully incorporated.
Once all the sugar is added whip frosting on medium low for a couple of minutes. This will add some air to your frosting and make it nice and fluffy.
