Ingredients:

  • 1 1/2 cups (150g) graham cracker crumbs
  • 1/2 cup (115g) unsalted butter, melted
  • 2 tbsp (25g) granulated sugar
  • 1/4 tsp (1g) salt
  • 12 oz (340g) semi-sweet chocolate chips
  • 2 cups (100g) mini marshmallows

Instructions:

  1. Preheat oven to 350°F (175°C) and line an 8x8 inch pan with parchment paper, leaving an overhang on the sides.
  2. Combine graham cracker crumbs, melted butter, sugar, and salt in a bowl and stir until the mixture resembles wet sand.
  3. Press the mixture firmly into the bottom of the pan using the back of a spoon until the surface is level and compacted.
  4. Bake for 8–10 minutes until the edges are fragrant and slightly golden, then remove from the oven.
  5. Immediately sprinkle chocolate chips evenly over the hot crust. Let sit for 2 minutes, then use a spatula to spread into a smooth layer.
  6. Pack mini marshmallows tightly on top of the chocolate, ensuring no gaps are left.
  7. Switch oven to Broil setting and place pan on the upper-middle rack.
  8. Broil for 1–3 minutes until marshmallows are puffed and have developed mahogany-colored peaks.
  9. Cool completely at room temperature before transferring to the fridge for 2 hours to set.
