What you will need

This recipe uses 6 simple ingredients that you can find at any grocery store:

  • 1.5 cups graham cracker crumbs
  • 5 tbsp unsalted butter melted divided
  • 1 box fudge brownie mix plus ingredients on box
  • 2 cups mini marshmallows
  • 0.5 cup semi sweet chocolate chips
  • 2 whole graham cracker sheets broken into pieces

Step by step instructions

Step 1: Make the Graham Cracker Crust

Mix graham cracker crumbs with three tablespoons of melted butter until the mixture resembles wet sand. Press it firmly and evenly into the bottom of a greased 9 by 13 inch baking pan.

Step 2: Add and Bake the Brownies

Prepare the brownie mix according to the package directions and pour the batter evenly over the graham cracker crust. Bake at 350 degrees F for 25 to 28 minutes until a toothpick comes out with just a few moist crumbs.

Step 3: Add Smores Toppings

Remove the pan from the oven and immediately scatter mini marshmallows, chocolate chips, and broken graham cracker pieces evenly over the hot brownie surface. Return the pan to the oven for two minutes.

Step 4: Toast and Cool

Switch the oven to broil and broil for one minute watching very carefully until the marshmallows are golden and toasted. Remove from the oven and let the brownies cool for at least 20 minutes before cutting into squares.
