These S’mores Seven Layer Bars are a decadent, gooey treat combining the classic flavors of graham crackers, marshmallows, and chocolate. With a crisp graham cracker crust, layers of melted sweetened condensed milk, mini marshmallows, chocolate chips, and chunks of chocolate bars, baked until golden and bubbly, these bars deliver the nostalgic taste of campfire s’mores in an easy-to-make dessert bar.

Ingredients

Scale

Crust

  • 2 1/2 cups graham cracker crumbs
  • 3/4 cup butter, melted

Layering

  • 1 (14 oz) can sweetened condensed milk
  • 2 cups mini marshmallows (divided)
  • 1 cup semi-sweet chocolate chips
  • 1 cup broken graham cracker pieces
  • 2 (1.55 oz) chocolate bars, broken into pieces

Instructions

  1. Preheat and Prepare: Preheat your oven to 350°F (177°C). Spray a 9×13 inch baking dish with non-stick cooking spray or line it with parchment paper to prevent sticking and make cleanup easier.
  2. Make Crust: In a small bowl, combine the graham cracker crumbs and melted butter. Mix thoroughly until the crumbs are evenly coated. Press this mixture firmly into the bottom of the prepared baking dish, creating an even crust layer.
  3. Add Sweetened Condensed Milk: Pour the sweetened condensed milk evenly over the crust, spreading it gently to cover the entire surface.
  4. Layer Marshmallows and Chocolate: Sprinkle half of the mini marshmallows evenly over the condensed milk. Then, add all of the semi-sweet chocolate chips and broken graham cracker pieces on top to create a rich, textured layer.
  5. Bake Initial Layers: Bake the bars in the preheated oven for 15 minutes. This will help set the layers and start melting the chocolate and marshmallows slightly.
  6. Add Remaining Marshmallows: Remove the baking dish from the oven and sprinkle the remaining mini marshmallows over the bars. This top layer will toast beautifully during the additional baking.
  7. Finish Baking: Return the dish to the oven and bake for an additional 10-15 minutes, or until the marshmallows on top are golden brown and the edges of the bars are a nice golden color.
  8. Add Chocolate Pieces and Cool: Remove the bars from the oven and immediately place the broken chocolate bar pieces on top. Let them sit for several minutes to allow the chocolate to soften and melt slightly.
  9. Cool and Serve: Transfer the baking dish to a cooling rack and allow the bars to cool for at least 15 minutes before cutting. For the best texture and easier slicing, allow the bars to cool completely. The bars will remain gooey yet hold together well for serving.

Notes

  • Ensure the marshmallows are evenly distributed to get that perfect s’mores flavor in every bite.
  • Using parchment paper makes it easier to lift the bars out of the baking dish after cooling.
  • For a variation, try using milk chocolate chips or adding a sprinkle of sea salt on top before baking.
  • Store leftovers in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
  • These bars can be reheated briefly in the microwave to bring back the gooey texture if desired.
