Notes

This buttercream is sweet, so you won't need a lot of it.
This recipe makes enough frosting to lightly cover about 2 dozen cupcakes or one, two (8" round) layer cake that already has filling.
If you like a really thick coating on your cakes, or you'll be using this as the filling in addition to the outer frosting, then you'll want to make a recipe plus a half, or just double the recipe.
How to Store: Because this frosting includes cream cheese, it needs to be stored in an airtight container, in the refrigerator and can last up to 5-6 days.
