Equipment

  • 1 8x8 metal pan
  • parchment paper
  • 1 saucepan for melting brown butter
  • 1 large bowl
  • 1 Whisk
  • 1 rubber spatula for mixing
  • 1 cutting board to chop chocolate
  • 1 sharp knife

Ingredients

  • ½ cup browned butter
  • ¼ cup cold butter cut into 4 pieces
  • 1 cup brown sugar
  • 2 eggs
  • 1 tsp vanilla extract
  • ½ cup all purpose flour
  • ½ cup graham cracker crumbs
  • ½ tsp salt
  • ½ tsp baking powder
  • 10 marshmallows sliced into thirds
  • cup dark chocolate chunks chopped
  • ¼ cup dark chocolate chips

Instructions

  • Preheat the oven to 375℉. Line your 8x8 pan with parchment paper.
  • Brown the butter. In a saucepan over medium heat, melt the butter. Stir it frequently to prevent it from burning. Keep heating until the butter foams and darkens to a shade of amber, about 3-4 minutes.
    Then remove the butter from the heat. In a large bowl, pour the browned butter over the remaining cold chunks of butter and whisk together until completely melted.

  • Add the brown sugar and whisk until well combined. Then add the eggs and vanilla extract and whisk together until homogenous.

  • Add the graham crackers to a food processor and pulse until you have fine crumbs. Then add the graham cracker crumbs to the batter until just combined and the crumbs have absorbed.
    Add the flour, salt and baking powder. Fold until just absorbed and combined.

  • Assemble. Add ⅔rds of graham cracker batter to the bottom of the pan and smooth out evenly. Then place the sliced marshmallows in a flat layer on top. Sprinkle on the chocolate chunks and chips into the remaining cracks.

  • Carefully spoon on the rest of the graham cracker dough, and try to smooth it out gently with your fingertips. It does not need to be an even layer - it will look nice to have chocolate or marshmallow peeking through.
  • Place in the oven and bake for 25-30 minutes until the center is not jiggling and it looks just set. The marshmallow will inflate, which is okay. They will shrink down as they cool. Slice and serve!
