Monster Cookie Bars
  1. Preheat oven to 350° F. Lightly butter a 12'' x 17'' jelly roll pan with 1 tablespoon of the butter. Set aside.

  2. In the bowl of a stand mixer, cream together remaining ½ cup butter, peanut butter, brown sugar, and sugar. Add eggs and vanilla, and mix until incorporated. Add flour, oats, baking soda, and salt, and mix again until incorporated.

  3. Reserve about ½ cup each of the chocolate chips and M&M's, and then fold the remaining into the batter with a spatula. Press the batter evenly into prepared pan. Sprinkle the reserved chocolate chips and M&M's over the top, pressing them in slightly. Bake for 14 to 15 minutes. These bars are meant to be chewy; do not over bake! Remove from oven and let pan cool completely on wire rack. Then cut into individual bars.
