Tips from the Betty Crocker Kitchens

  • tip 1
    Greasing the pan before adding parchment will help keep the parchment in place while you spread the cookie dough layer in the pan. Use mini metal binder clips to secure the parchment overhang.
  • tip 2
    You can use all peanut butter creme-filled sandwich cookies or all peanut butter cup candies in this recipe; whatever you do, it will be delicious!
