Ingredients

  • ¾ c. butter softened
  • ½ c. peanut butter creamy
  • ¾ c. brown sugar
  • ¼ c. white sugar
  • 2 eggs
  • 2 T. milk
  • 1 1/3 c. white rice flour
  • 2/3 c. tapioca starch
  • 1 ¼ t. xanthan gum
  • or 2 c. 1 to 1 gluten free flour instead of the above 3 ingredients
  • ½ t. salt
  • 1 t. baking soda
  • ½ c. gluten free graham crackers crushed
  • 1-12 oz. bag chocolate chips
  • 4 c. miniature marshmallows

Instructions

  1. Heat oven to 350 degrees.
  2. In a large mixing bowl combine butter, peanut butter and sugars. Mix on medium-low speed for 2 minutes. Add eggs and milk and mix for 1 minute.
  3. In a separate medium-sized bowl combine white rice flour, tapioca starch, xanthan gum, salt and baking soda. Toss to combine and then slowly incorporate the dry ingredients into the butter/sugar mixture.
  4. Add graham cracker crumbs to dough and thoroughly combine.
  5. In a large, 10 x 15 inch sheet pan, completely coated in non-stick cooking spray, spread peanut butter cookie dough out evenly.
  6. Bake for 14-17 minutes, or until almost completely done. Spread entire bag of chocolate chips on almost done cookie crust and return to oven for 3 minutes.
  7. Add marshmallows and return to oven. Place oven on a High broil and broil bars for 2 minutes, paying close attention to them so they do not burn.
  8. Let bars cool completely before cutting. Be sure to use a sharp knife since the marshmallows will be gooey. If you are having trouble cutting the bars without making a sticky mess, refrigerate for at least 4 hours and then cut. Enjoy!
