peanut butter cream cheese brownies

I had forgotten about these brownies until a friend dropped off a Christmas treat and mentioned that she would like the recipe.  Here it is!  I am sure I copied it from the blog Brown Paper Packages then adapted it a bit but I can't find it on the site anymore.

peanut butter cream cheese brownies 
1 box family-size brownie mix, baked according to package directions
1 package cream cheese, softened
1/2 cup peanut butter
1/2 cup to 3/4 cup powdered sugar
1 cup semi-sweet chocolate chips
5 tablespoons butter


Bake your brownie mix according to package directions then let cool completely.  Beat the cream cheese until fluffy then add peanut butter and mix well.  Slowly add the powdered sugar and beat until fully incorporated.  Spread the cream cheese mixture over the brownies evenly.  Refrigerate until you are ready to cut and serve.
