I know I said I would be making cookies, but that was before I found this recipe. MMMMMMMMMmmmmmmmmmmm. Yuuuummmmyy. I just tried my first bite and had to go back for more. It's killing me to wait until tomorrow for another taste. I did make a couple of changes to the recipe after reading the reviews. First, I used a 9" x 13" pan. Second, I used 2 cups of milk chocolate chips. Third, I only used about 5 tablespoons of butter for the topping. When measuring I was easy on the confectioner's sugar and generous on the peanut butter, graham cracker crumbs, and chocolate chips. I highly recommend you try your own version.
