These easy homemade s’mores bars combine a buttery graham cracker crust, rich chocolate layer, and gooey toasted marshmallow topping for a nostalgic, crowd-pleasing dessert.

Ingredients

Scale
  • 1 ½ cups graham cracker crumbs (about 10 full sheets, finely crushed)
  • 6 tablespoons unsalted butter, melted
  • ¼ cup granulated sugar
  • 1 teaspoon vanilla extract (optional)
  • 1 ½ cups semi-sweet chocolate chips
  • ½ cup heavy cream
  • 3 cups mini marshmallows
  • Flaky sea salt (optional)

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.
  2. In a medium bowl, combine graham cracker crumbs, melted butter, granulated sugar, and vanilla extract if using. Mix until evenly coated and mixture holds when pressed.
  3. Press the crust mixture firmly into the bottom of the prepared pan using the back of a measuring cup for an even base.
  4. Bake the crust for 8-10 minutes until lightly golden and set. Remove from oven and let cool slightly.
  5. In a microwave-safe bowl or double boiler, heat chocolate chips and heavy cream until smooth and glossy, stirring frequently to avoid burning.
  6. Pour the melted chocolate mixture over the warm crust and spread evenly with a spatula.
  7. Sprinkle mini marshmallows evenly over the chocolate layer.
  8. Bake for an additional 10-12 minutes until marshmallows puff up and turn light golden brown. Optionally, broil for 1-2 minutes for extra toasting, watching carefully.
  9. Remove from oven and cool completely on a wire rack. Chill in the fridge for 30 minutes if desired to speed setting.
  10. Use parchment overhang to lift bars from pan and cut into 16 squares with a sharp knife, wiping blade between cuts.

Notes

Use fresh mini marshmallows for best gooey texture. Press crust firmly to prevent crumbling. Cool bars completely before cutting for clean squares. Watch marshmallows closely under broiler to avoid burning. For gluten-free, substitute graham cracker crumbs with gluten-free crackers or almond flour. Vegan options include dairy-free butter, coconut cream, dairy-free chocolate chips, and vegan marshmallows.
