These crispy browned butter s’mores bars feature a rich graham cracker crust with a nutty caramelized butter flavor, topped with melty chocolate and toasted marshmallows for a nostalgic yet elevated treat.

Ingredients

Scale
  • 1 ½ cups graham cracker crumbs (about 10 full sheets, finely crushed)
  • 6 tablespoons unsalted butter, browned and slightly cooled
  • 2 tablespoons granulated sugar
  • ¼ teaspoon salt
  • 1 ½ cups semi-sweet chocolate chips or chunks
  • 2 cups mini marshmallows
  • Optional: flaky sea salt for sprinkling on top

Instructions

  1. Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving an overhang on two sides for easy removal.
  2. In a medium saucepan over medium heat, melt 6 tablespoons of unsalted butter. Stir frequently as it foams and then starts to brown, about 5-7 minutes. Remove from heat and let cool slightly for about 5 minutes.
  3. In a mixing bowl, combine 1 ½ cups graham cracker crumbs, 2 tablespoons granulated sugar, and ¼ teaspoon salt. Pour in the browned butter and stir until the mixture is evenly moistened and resembles wet sand.
  4. Transfer the crust mixture to the prepared pan. Press firmly and evenly into the bottom using the back of a spoon or your fingers. Bake for 10 minutes until golden and fragrant. Remove from oven and let cool slightly.
  5. Sprinkle 1 ½ cups semi-sweet chocolate chips evenly over the warm crust. Layer 2 cups mini marshmallows on top, pressing down lightly so they stick.
  6. Place the pan under the oven broiler on the top rack for 1-3 minutes. Watch closely until marshmallows puff and turn golden brown, then remove.
  7. Let the bars cool completely in the pan on a wire rack for about 1 hour to set the chocolate and crisp the crust.
  8. Use the parchment paper overhang to lift the bars from the pan. Cut into 12 squares with a sharp knife. Sprinkle with flaky sea salt if desired.

Notes

Use medium heat and stir often when browning butter to avoid burning. Cool butter slightly before mixing with crust ingredients to prevent sogginess. Press crust firmly for best results. Watch marshmallows closely under broiler to avoid burning. Warm knife in hot water for clean slicing. Bars taste better after resting and can be stored at room temperature or refrigerated.
