Ingredients

For the Graham Cracker Crust:

  • 2 cups graham cracker crumbs about 12 cracker sheets
  • 1 stick salted butter melted
  • 1/3 cup sugar

For the brownie layer:

  • 1 18.4 ounce box Chocolate Fudge Brownie mix
  • + oil water and eggs to prepare per package instructions.

For the Marshmallow Buttercream Frosting:

  • 1 7 ounce container Marshmallow Fluff
  • 1 stick salted butter softened
  • 1 1/2 cups powdered sugar
  • Decorate with mini chocolate chips and graham cracker crumbs if desired.

Instructions

  • Preheat your oven to 350 degrees.
  • Prepare graham cracker crust by mixing the ingredients together with a fork until the cracker crumbs are well moistened by the butter. Press them into the 9x13 baking dish using the back of the fork.
  • Prepare the brownie mix (or feel free to use your own homemade recipe) as instructed on the box. Pour the brownie batter over the graham cracker crust and gently spread it out evenly. Take care not to lift the crust while you spread the batter out.
  • Bake for 25-30 minutes or until a toothpick inserted in the center of the brownies comes out clean.
  • Cool completely before frosting.
  • To prepare the frosting, cream your butter in your mixer until fluffy. (two minutes or so) Add in the Marshmallow Fluff and beat until combined. Slowly add in the powdered sugar. Add more if you want a thicker consistency. Beat until smooth. Spread over cooled brownies.
  • Sprinkle with mini chocolate chips and graham cracker crumbs if desired.
