For the cream cheese frosting, combine the softened cream cheese and butter in a large bowl with a hand held mixer until creamy and smooth. Add vanilla and powdered sugar and continue to mix. Add enough milk to get the consistency you want.
Add to the top of cakes, cookies or bars. Store in the refrigerator for up to 4 days.
Notes
Feel free to customize by adding cocoa powder, a fruit jam, lemon zest, or cinnamon!
