Introduction

These S’mores Seven Layer Bars bring the classic campfire treat into your kitchen with layers of graham crackers, chocolate, and gooey marshmallows. Perfect for parties or a sweet family snack, they combine crunchy, chewy, and melty textures in every bite.

The image shows a close-up of a stack of three s'mores bars resting on white parchment paper over a white marbled texture. Each square bar has three visible layers: a thick golden brown crumbly base, a middle melting layer of gooey white marshmallow and soft chocolate, and a top layer scattered with toasted marshmallows, rough pieces of golden brown graham cracker, and chunky dark chocolate chunks and chips. The bars have a rich texture contrast with the soft melting middle and crunchy toppings, and the edges reveal pockets of melted chocolate and marshmallow inside.

Ingredients

2 1/2 cups graham cracker crumbs
3/4 cup butter, melted
1 (14 oz) can sweetened condensed milk
2 cups mini marshmallows
1 cup semi-sweet chocolate chips
1 cup broken graham cracker pieces
2 (1.55 oz) chocolate bars, broken into pieces

Instructions

Step 1: Preheat your oven to 350°F (175°C). Lightly spray a 9×13 inch baking dish with non-stick cooking spray or line it with parchment paper for easy removal.
Step 2: In a small bowl, combine the graham cracker crumbs and melted butter until evenly mixed. Press this mixture firmly into the bottom of the prepared baking dish to form the crust.
Step 3: Pour and spread the sweetened condensed milk evenly over the crust.
Step 4: Sprinkle half of the mini marshmallows, all the semi-sweet chocolate chips, and the broken graham cracker pieces evenly on top.
Step 5: Bake the bars for 15 minutes, then carefully remove them from the oven.
Step 6: Sprinkle the remaining mini marshmallows over the partially baked bars, then return the dish to the oven and bake for an additional 10 to 15 minutes. Bake until the marshmallows are golden brown and the edges are slightly crisp.
Step 7: Remove the bars from the oven and immediately place the broken chocolate bar pieces on top to melt slightly from the residual heat.
Step 8: Allow the bars to cool on a wire rack for at least 15 minutes before cutting. They will be gooey but should hold together for serving. For best texture, let them cool completely.

Tips & Variations

For extra crunch, toast the graham cracker pieces lightly before adding them to the bars.
Swap semi-sweet chocolate chips for milk or dark chocolate chips to vary sweetness.
Add a sprinkle of sea salt on top before baking for a salty-sweet contrast.
Use regular-sized marshmallows if mini marshmallows are not available; just cut them into smaller pieces.

Storage

Store leftover bars in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the refrigerator for up to a week. Reheat briefly in the microwave if you prefer a melty texture, but avoid overheating to prevent marshmallow toughness.

How to Serve

The image shows multiple square dessert bars arranged neatly on crinkled white parchment paper over a white marbled surface. Each bar has three visible layers: the bottom layer is a crumbly golden brown crust, the middle layer is a mix of melted marshmallow and chocolate chips creating a gooey texture, and the top layer is decorated with toasted mini marshmallows, Hershey chocolate pieces, and scattered dark chocolate chips. The bars have an inviting mix of light and dark brown colors with a soft, melty look and a slightly toasted texture on the marshmallows. Photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use a different type of chocolate for these bars?

Yes, you can substitute semi-sweet chocolate with milk, dark, or even white chocolate chips depending on your preference. Just keep in mind that different chocolates may change the sweetness and texture slightly.

How do I prevent the marshmallows from burning?

Keep an eye on the marshmallows during the final baking stage. If they start browning too quickly, you can loosely cover the dish with foil to prevent burning while still allowing the bars to cook through.

Scale

Crust

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

Filling and Toppings

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 each) chocolate bars, broken into pieces

Instructions

Preheat and Prepare: Preheat your oven to 350°F (175°C). Spray a 9×13 inch baking dish with non-stick cooking spray or line it with parchment paper for easy removal and cleanup.
Make the Crust: In a small bowl, combine the graham cracker crumbs and melted butter thoroughly. Press this mixture firmly and evenly into the bottom of the prepared baking dish to create the crust layer.
Add Sweetened Condensed Milk: Pour the can of sweetened condensed milk evenly over the graham cracker crust, spreading it gently with a spatula to cover the entire surface.
Layer Marshmallows, Chocolate Chips, and Crackers: Sprinkle half of the mini marshmallows, all of the semi-sweet chocolate chips, and broken graham cracker pieces evenly over the condensed milk layer.
Bake First Stage: Place the baking dish in the preheated oven and bake for 15 minutes, allowing the ingredients to meld and the chocolate chips to soften.
Top with Remaining Marshmallows and Bake: Remove the dish from the oven and sprinkle the remaining mini marshmallows over the top. Return the dish to the oven and bake for an additional 10 to 15 minutes or until the marshmallows are golden brown and the edges of the bars are starting to turn golden.
Add Chocolate Bar Pieces and Cool: Remove the bars from the oven and immediately sprinkle the broken chocolate bar pieces on top to melt slightly. Place the dish on a cooling rack and allow the bars to cool at least 15 minutes before cutting.
Serve and Enjoy: For best results, allow the bars to cool completely to set. Cut into squares and enjoy the gooey, melty, layered s’mores bars.

Notes

Press the crust mixture firmly into the pan to ensure it holds together well.
Use parchment paper for easier removal of bars from the pan.
You can substitute any chocolate bars you like for variety, such as milk chocolate or a nutty chocolate bar.
These bars are best served after fully cooling to ensure they set properly but are still delightfully gooey.
Store leftovers in an airtight container at room temperature for up to 3 days or refrigerate to extend shelf life.
