Cookie dough mixture

  • cups all-purpose flour

  • 1 cup brown sugar

  • 2 large eggs
  • 2 teaspoon vanilla extract
  • 1 teaspoon salt

S'mores bars

  • Preheat oven to 350°. Grease a 9x13 in cake pan with non-stick spray. Set aside. In a medium sized mixing bowl, add the graham cracker crumbs, melted butter, and granulated sugar and mix until well combined. Pour mixture and press firmly into cake pan and bake for 6 minutes. Remove from oven and set aside.
  • In another mixing bowl, cream butter, both sugars together. Add in both eggs and vanilla extract and beat until light and fluffy. Mix in flour, baking soda and salt until combined. By hand, mix in marshmallows and chocolate chips.
  • Evenly spread cookie dough mixture over crust and gently press it on so you don't disrupt the crust beneath it. Bake for 18-20 minutes, remove from oven, place hershey bars on top and additional marshmallows. Return to oven for an additional 10 minutes until golden brown on top. The center should be slightly undercooked and on gooey side.
  • Remove from oven and allow to cool completely before serving!
