These Ultimate Gooey S’mores Bars are a nostalgic, mess-free twist on the classic campfire treat, featuring a crunchy graham cracker crust, melty chocolate, and a toasty marshmallow topping.

Ingredients

Scale
  • 2 cups finely crushed graham crackers (about 200g)
  • 6 tablespoons (85g) unsalted butter, melted
  • 1/4 cup (50g) light brown sugar
  • 1 1/2 cups (270g) semi-sweet chocolate chips (mix with milk chocolate chips if desired)
  • 3 cups large marshmallows (or about 50 mini marshmallows, or large marshmallows cut in halves)
  • 1 teaspoon vanilla extract
  • Pinch of salt

Instructions

  1. Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper, leaving an overhang on the sides for easy removal.
  2. Crush the graham crackers finely using a food processor or a plastic bag and rolling pin.
  3. In a medium bowl, mix the crushed graham crackers with melted butter, light brown sugar, and a pinch of salt until the mixture resembles wet sand.
  4. Press the crust mixture firmly into the bottom of the prepared pan using the back of a measuring cup to pack it evenly and tightly.
  5. Bake the crust for 10 minutes until lightly golden and fragrant.
  6. Sprinkle the semi-sweet chocolate chips evenly over the warm crust.
  7. Top with marshmallows, spreading them evenly to cover the chocolate layer.
  8. Bake again for 12-15 minutes, watching closely until marshmallows puff up and turn golden brown but do not burn.
  9. Remove from oven and let cool completely (about 30 minutes) to set the bars.
  10. Use the parchment paper overhang to lift the bars out of the pan and cut into squares with a sharp knife, wiping the knife between slices to avoid sticking.

Notes

Pre-bake the crust to avoid sogginess. Do not press marshmallows down to allow puffing. Watch marshmallows closely to prevent burning. Let bars cool completely before cutting for clean slices. For extra toasty marshmallows, broil for 30 seconds but watch carefully. Store in airtight container at room temperature for up to 2 days or refrigerate for up to a week. Reheat briefly in microwave to restore gooey texture.
