In a medium saucepan melt the butter and brown sugar. Whisk together over medium-high heat until sugar has dissolved, about 4 minutes. Remove from heat and whisk in vanilla extract. Set aside and let cool, if you're in a hurry stick in the freezer for about 15 minutes.
In the meantime cream together the cream cheese and confectioners? sugar for 1-2 minutes. Slowly pour in the butter/sugar mixture. Beat on medium-high until the mixture is combined and not separated. It may take up to 5 minutes. Stir in the chocolate chips.
Serve with graham crackers, vanilla wafers, strawberries, or anything else that sounds good.
