Your favorite peanut butter cookie recipe. I used this one. Press into the bottom of a 9x13 baking sheet. Bake at 350* for 12-15 minutes or until the sides start to brown. Allow to cool for 5 minutes. Melt 2 cups chocolate chips and spread over top.
Very easy and very tasty. The only thing I would do different next time is use milk chocolate chips instead of semi-sweet. I was using what was in my pantry and that is all that I had. I have several bars cut and in the freezer to add to Chuck's lunch box. Enjoy!
