Ingredients

  • 1 ½ cups graham cracker crumbs 21 squares
  • 6 tablespoons melted butter

Brownie Layer

  • 16 tablespoons unsalted butter 2 sticks
  • 8 ounces bitter sweet chocolate 70% cocoa, finely chopped
  • 1 ¾ cups light brown sugar
  • 3 large eggs at room temperature
  • 2 teaspoons vanilla extract
  • ¾ cup all purpose flour
  • ½ cup dutch processed cocoa powder
  • ¾ teaspoon sea salt

Marshmallow Topping

Instructions

Graham Cracker Crust

  • Preheat the oven to 350°F. Line an 8x8 inch pan with parchment paper. Set aside.
  • In a food processor, pulse the graham crackers until only crumbs remain. and Add the melted butter and pulse to combine.
  • Transfer the crumb mixture to into the prepared pan and press down into an even layer. Set aside.

Brownie Layer

  • In a large microwaveable bowl, add the butter and chopped chocolate. Heat the mixture in 30-second intervals at 50 % power. After each interval, remove the bowl and stir the contents thoroughly. As the chocolate and butter approach a fully melted state, reduce the heating time to short bursts of 5-10 seconds. Continue until both the chocolate and butter are completely melted. Set aside to cool slightly.
  • Add the sugar and eggs to the bowl of a stand mixer or large mixing bowl. Beat the mixture on medium speed for approximately 5 minutes, or until the mixture has doubled in size and achieved a pale yellow color.
  • Turn the mixer off and pour the cooled butter and chocolate mixture, along with the vanilla extract, into the bowl. With the mixer on its lowest setting, mix until a uniform color is achieved throughout the batter. Scrape down the sides and bottom of the mixing bowl to ensure all the ingredients are completely incorporated.
  • In a separate bowl, add the flour, cocoa powder and salt. Whisk to combine.
  • Add the dry ingredients to the wet ingredients. Use a hand held spatula or wooden spoon to gently fold the ingredients together. Do not over mix.
  • Carefully pour the brownie batter into the prepared pan with the graham cracker crust. Use the back of a spoon or an offset spatula to smooth the top.
  • Place the pan on the center rack and bake for 35 minutes. To determine doneness, carefully insert a toothpick into the center of the pan. The toothpick should have moist crumbs clinging to it, but not large chunks of uncooked batter.
  • Remove the brownies from the oven and arrange the marshmallows in rows on top of the brownie. Return the pan to the oven for 3 minutes. At this stage, you can use a chef’s blowtorch to toast the tops of the marshmallows or set the pan under a hot broiler for 30 seconds.
  • Leave to cool completely in the pan before slicing into squares.
  • Serve and enjoy!
