  • 1 1/2 cup graham cracker crumbs
  • 3 tablespoons sugar
  • 1/3 cup melted butter
  • 1 box of brownie mix, plus required ingredients
  • 1 bag of mini marshmallows


  • Preheat the oven to 350°F. Prepare the graham cracker crust by mixing them together the crumbs, butter and sugar.
  • Place a sheet of parchment paper in the bottom of a 9 x 9 square brownie pan. Press the graham cracker crumbs into the bottom of the pan on top of the parchment.
  • Bake the graham cracker crust for 12 to 14 minutes until lightly browned. Remove the pan from the oven and allow to cool for a few minutes while preparing the brownie mix according to the package directions. (You'll most likely need eggs and oil to prepare the brownie batter.)
  • Pour the brownie batter on top of the graham cracker crust and return the pan to the oven for 40 to 45 minutes or until the brownies have finished cooking.
  • Remove the brownies and add enough mini marshmallows on top to completely cover the brownies.
  • Switch your oven to the broil function. Place the brownie pan in the oven with the door slightly ajar. The marshmallows will begin to brown very quickly, within a minute, so stay close to the oven and remove the pan from the stove to prevent burning.
  • Allow the brownies to cool completely. Spray a sharp knife with cooking spray before slicing the brownies into bars.
