  • 125 g graham cracker crumbs (approx. 9 full-sheet crackers)
  • 65 g granulated sugar
  • 85 g unsalted butter melted
  • 28-32 large marshmallows (about 200g)
  • 285 g dark chocolate (70% cacao)
  • flaky sea salt to taste


  • Preheat oven to 350°F (180°C). Grease and line an 8x8-inch baking pan with parchment paper, ensuring that the paper along the long sides extends above the pan to act as handles to remove from the pan later. Set aside.
  • Combine graham cracker crumbs and sugar in a medium bowl, add butter and mix with a fork until uniform. Reserve approximately 1-2 tablespoons of the graham cracker crumbs .

  • Press crackers down into the baking pan using the back of a glass or a tart tamper. Bake crust for 10 minutes or until slightly golden.
  • Place marshmallows on top of the baked graham cracker crust, side by side leaving little to no gap in between each marshmallow.

  • Melt chocolate in the microwave, heating in 30-second intervals and mixing thoroughly between each interval. Mix until completely smooth and melted.

  • Top marshmallows with the melted chocolate and sprinkle reserved graham cracker crumb over the top. Bake for 10-12 minutes to allow the marshmallows to melt.
  • Once out of the oven, transfer pan to a cooling rack and sprinkle the flaky sea salt. Once the s’mores are cooled, transfer to the freezer for 10-15 minutes (for the chocolate to fully set).
