Butter Bars: Combine everything and mix well. Pour into a nonstick or greased 9x13 pan. Bake at 325 for 20-22 minutes. Let it cool complete, then frost with cream cheese frosting. Refrigerate for 2 hours or more. Cut with a hot knife for clean, crisp edges.
Cream Cheese Frosting: Whip cream cheese with a mixer and then add sugar and milk until the frosting reaches the thickness you like. You can add more sugar for sweeter frosting or less for more tart.
