Instructions
 

  • Preheat the oven to 350°F (175°C). Grease a 9x13-inch baking pan or line it with parchment paper.
  • 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, mixing well after each addition. Stir in the vanilla extract.
  • In a separate bowl, whisk together the flour, baking soda, and salt.
  • Gradually add the dry ingredients to the butter mixture, mixing just until combined. Do not overmix.
  • Fold in the graham cracker crumbs and chocolate chips until evenly distributed.
  • Spread half of the cookie dough evenly into the prepared baking pan.
  • Sprinkle the mini marshmallows over the dough, then gently spread the remaining cookie dough over the top.
  • Top with extra chocolate chips and mini marshmallows if desired.
  • Bake for 25–30 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.
  • Cool the bars in the pan for about 10 minutes, then transfer to a wire rack to cool completely before slicing into squares.

Notes

For extra flavor, stir chopped nuts into the dough or substitute milk, dark, or white chocolate chips. Let the bars cool completely before slicing for clean squares.
