Here's a recipe that I got from my boss. We had this at a work function not too long ago. It was a tasty treat! (So tasty, in fact, that my co-worker and I had more of it today!)
1 Stick of butter, softened
8 oz cream cheese
1/3 cup brown sugar
1/3 cup confectioners sugar
2 tbsp. vanilla extract
mini chocolate chips
mix everything together and serve with graham crackers, teddy grahams, or any other sweet treat of your choice.
I was thinking about it, and this might work as a truffle filling too!
