  • 1 cup Butter room temperature
  • 1 cup Sugar
  • 1 cup Light Brown Sugar
  • 1 tsp Vanilla Extract
  • ½ tsp Salt
  • 2 large Eggs
  • 1 tsp Baking Powder
  • 2 cups All-Purpose Flour
  • 2 cups Chocolate Chips mini or regular
  • 2 cups Graham Crackers crushed into pieces no larger than 1"
  • 2 cups Mini Marshmallows
  • 3 bars Hershey's Chocolate broken into individual pieces and frozen


  • Preheat oven to 350 degrees.
  • In a medium mixing bowl, cream together the room temperature butter, sugar, and brown sugar using a spatula, or the paddle attachment for a stand mixer. Beat until light and fluffy, or about 2 minutes.
  • Add in the vanilla and salt and mix to combine, then slowly add the eggs, mixing on low to combine.
  • In a separate bowl, whisk together the baking powder and flour, and add into the butter mixture, mixing on low just until combined. Once your dough is almost completely combined, add the chocolate chips and crushed graham crackers and gently fold in by hand.
  • Remove dough from the bowl and press into the greased cookie sheet as evenly as possible.
  • Bake in a preheated oven for about 20 minutes, or until the edges are golden brown and the large cookie has begun to set. Remove from the oven and spread the mini marshmallows evenly over the top, then return to the oven for about 10 more minutes, until the marshmallows begin to melt and brown slightly.
  • Remove from the oven and let cool for about 1 minute, then place the frozen Hershey's Chocolate pieces evenly over the top. Cool completely before cutting into bars. Enjoy!
