Ingredients
  

  • 1 cup unsalted butter softened
  • 1 cup brown sugar packed
  • 1 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 1/2 cups graham cracker crumbs
  • 1 cup semi-sweet chocolate chips
  • 2 cups mini marshmallows

Instructions
 

  • Preheat the oven to 350°F (175°C) and grease a 9×13 inch baking pan.
  • In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy. Beat in the eggs one at a time, followed by the vanilla extract.
  • In a separate bowl, whisk together the all-purpose flour, baking soda, salt, and graham cracker crumbs.
  • Gradually add the dry ingredients to the wet mixture, mixing until combined. Fold in the chocolate chips to the dough.
  • Spread half of the cookie dough evenly into the prepared baking pan. Sprinkle mini marshmallows over the dough, followed by the remaining cookie dough on top.
  • Bake for 20-25 minutes, or until the top is golden brown.
  • Allow the cookie bars to cool in the pan before cutting them into squares. Serve warm for the ultimate treat.
