Ingredients

Cookie Base

  • 1 cup unsalted butter (softened)
  • 1 cup brown sugar
  • 1/2 cup granulated sugar
  • 2 eggs
  • 2 teaspoons vanilla extract
  • 2 1/2 cups all-purpose flour
  • 2 teaspoons baking powder
  • 1/2 teaspoon salt
  • 1 1/2 cups graham cracker crumbs

Fillings

  • 1 cup semi-sweet chocolate chips or chunks
  • 1 1/2 cups mini marshmallows or marshmallow fluff
  • 2-3 bars full-size Hershey bars (optional) Optional for additional chocolate layer

Instructions

Preparation

  • Preheat your oven to 350°F (175°C) and prepare a 9x13-inch baking dish by lining it with parchment paper or lightly greasing it.
  • In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy (about 2-3 minutes).
  • Beat in the eggs one at a time, mixing in the vanilla extract.
  • In a separate bowl, whisk together the all-purpose flour, baking powder, salt, and graham cracker crumbs.
  • Gradually mix the dry ingredients into the wet mixture until a thick dough forms.
  • Fold in the semi-sweet chocolate chips or chunks.

Assembly

  • Press two-thirds of the cookie dough evenly into the bottom of the prepared baking dish.
  • Spread marshmallow fluff evenly over the cookie base or sprinkle mini marshmallows.
  • If using, break Hershey bars into pieces and add over the marshmallows.
  • Drop remaining cookie dough by spoonfuls over the top, spreading slightly.

Baking

  • Bake in the preheated oven for 25-30 minutes until the top is golden brown.
  • Let the bars cool completely in the pan before slicing into squares.

Notes

For optimal results, avoid overmixing the batter and let the bars cool completely to avoid crumbling when cutting. Store leftovers in an airtight container.
