S’mores Seven Layer Bars are a nostalgic, indulgent dessert that layers all the classic s’mores ingredients—graham crackers, chocolate, marshmallows, and more—into a convenient, portable bar form. These rich, chewy bars combine crunchy textures with gooey marshmallow and melted chocolate, making them a favorite for potlucks, camping trips, or anytime you crave the flavors of a campfire treat without the fire.
The History of S’mores Seven Layer Bars
The classic s’more—a toasted marshmallow and chocolate sandwiched between two graham crackers—has been a beloved American campfire treat since at least the early 1900s, with its name reportedly originating from “some more” because everyone wanted seconds. Over time, home bakers and dessert enthusiasts began translating these flavors into baked goods for easier preparation and sharing. The seven layer bar, also known as a magic bar, traditionally layers seven ingredients such as nuts, coconut, chocolate chips, and condensed milk on a graham cracker crust. Merging s’mores components with this layered bar style created the S’mores Seven Layer Bar, blending the campfire nostalgia with the convenience of a classic dessert bar. This fusion has grown in popularity with the rise of creative baking and comfort food trends, celebrated for its simplicity, deliciousness, and playful textures.
Ingredients Breakdown
▢ 2 cups graham cracker crumbs
▢ ½ cup unsalted butter, melted
▢ 1 cup semisweet chocolate chips
▢ 1 cup mini marshmallows
▢ 1 cup sweetened shredded coconut
▢ ½ cup chopped nuts (walnuts or pecans)
▢ 1 (14-ounce) can sweetened condensed milk
Step-by-Step Recipe:
Preheat the oven to 350°F (175°C). In a medium bowl, mix the graham cracker crumbs and melted butter until well combined. Press this mixture evenly into the bottom of a greased 9×13-inch baking pan to form the crust. Sprinkle the chocolate chips evenly over the crust, followed by an even layer of mini marshmallows. Next, add the shredded coconut and chopped nuts, spreading them evenly. Pour the sweetened condensed milk slowly and evenly over all the layers to bind the ingredients together. Bake in the preheated oven for 25–30 minutes, or until the top is golden brown and the edges are bubbly. Let the bars cool completely in the pan before cutting into squares.
Tips for the Perfect Bars
Press the crust firmly and evenly for a sturdy base. Use fresh mini marshmallows for the best gooey texture—avoid old or stale marshmallows. Pour the sweetened condensed milk slowly and evenly to prevent pooling and ensure even binding. Allow the bars to cool fully to set properly before slicing. For easier cutting, chill the bars briefly in the refrigerator. Line the baking pan with parchment paper for easier removal.
Variations and Customizations
Substitute milk or dark chocolate chips to vary the chocolate intensity. Add a layer of peanut butter or drizzle peanut butter on top before baking for a nutty twist. Use gluten-free graham cracker crumbs to accommodate dietary needs. Incorporate dried fruit like cranberries or cherries for a sweet-tart contrast. Swap nuts for sunflower seeds or omit them for a nut-free version. Top with crushed graham crackers after baking for extra crunch.
Health Considerations and Nutritional Value
These bars are a rich dessert high in sugars, fats, and calories, making them best enjoyed occasionally. They provide energy and satisfaction but should be consumed in moderation, especially for those managing blood sugar or weight. Choosing reduced-fat butter or lower-sugar chocolate chips can slightly reduce calories. Gluten-free substitutions make the recipe accessible for those with gluten intolerance. While not a health food, the bars can be part of a balanced diet when balanced with nutrient-rich meals.

S’mores Seven Layer Bars
Ingredients
- 2½ cups graham cracker crumbs
- ¾ cup melted butter
- 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
- Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with non-stick cooking spray or line it with parchment paper. In a small bowl, combine the graham cracker crumbs and melted butter, then press the mixture firmly into the bottom of the prepared dish. Pour the sweetened condensed milk evenly over the crust.
- Sprinkle half of the mini marshmallows, all of the chocolate chips, and the broken graham cracker pieces over the top. Bake for 15 minutes. Remove the dish from the oven and evenly scatter the remaining marshmallows on top. Return to the oven and bake for another 10–15 minutes, or until the marshmallows are golden brown and the edges are nicely browned.
- Take the bars out of the oven and place the broken chocolate bar pieces over the hot surface. Let them sit for a few minutes to melt slightly. Transfer to a cooling rack and allow to cool for at least 15 minutes before slicing and serving. The bars will be gooey but should hold together. For the best texture and ease of cutting, let them cool completely before serving.
