Ingredients
Graham cracker crust
  • 2 1/4 cups graham crackers (1 1/2 sleeves), crushed
  • 2/3 cup butter, melted
  • 1/3 cup granulated sugar
Cookie top
  • 1/2 cup butter, softened
  • 1/2 cup shortening
  • 3/4 cup granulated sugar
  • 3/4 cup brown sugar
  • 2 eggs
  • 1 teaspoon vanilla
  • 2 1/4 cups flour
  • 1 teaspoon salt
  • 1 teaspoon baking soda
  • 2 cups miniature marshmallows
  • 1 cup semi-sweet chocolate chips
  • 3 Hershey bars, broken up
Instructions
  1. Preheat the oven to 350 degrees. In a medium bowl, mix together the graham cracker crumbs, melted butter, and sugar using a fork, then press the crumb mixture into the bottom of a 13×9-inch rectangular greased baking dish. Bake for 7 minutes, then remove from oven and allow to cool slightly.
  2. Meanwhile, cream the butter, shortening, and sugars together. Add in eggs and vanilla and beat well until light and creamy. Stir in flour, salt and baking soda just until combined. Then mix in the chocolate chips and marshmallows by hand.
  3. Carefully spread cookie mixture over the graham cracker crust by dropping spoonfuls of batter evenly around the dish and then gently pressing it together so you aren't disturbing the graham cracker crust beneath.
  4. Bake for 12 minutes at 350 degrees, then quickly remove from the oven, top with broken pieces of Hershey Bars and return to oven to finish baking. Bake 15-18 minutes more, until golden brown on top. The center should be mostly set but still just a little undercooked. Don't overcook - you want to eat these just a little on a the gooey side, trust me. Remove and allow to cool before cutting and serving.
