No-bake s'mores bars deliver all the gooey chocolate-marshmallow goodness of campfire s'mores in a quick, simple dessert. These bars are my answer to summer cravings when building a fire just is not an option but you want that nostalgic treat in your kitchen anytime.
I remember whipping up my first batch during a rainy weekend at home and my kids thought we had pulled off a magic trick by skipping the campfire altogether.
Ingredients
- Graham cracker crumbs: Bring classic s'mores flavor and crunch Choose fresh crackers for best taste
- Unsalted butter: Binds the base and offers rich taste Use high quality for a velvety finish
- Granulated sugar: Gives the crust a touch of sweetness Opt for pure cane sugar if possible
- Mini marshmallows: Essential for that chewy authentic layer Check for vegetarian options if needed
- Semisweet chocolate chips: Rich chocolate flavor that balances the sweetness Select real chocolate for smooth melting
- Heavy cream: Makes the chocolate layer extra silky Use cold cream for quicker thickening
- Extra graham crackers and chocolate chips: These add the perfect crunchy gooey topping I always use fresh toppings for best texture
Step-by-Step Instructions
- Line Baking Pan:
- Line an eight inch square baking pan with parchment paper making sure there is some hanging over the sides for easy removal later. This helps lift out the bars cleanly once they are set.
- Mix and Press the Crust:
- In a medium bowl combine graham cracker crumbs melted butter and sugar. Stir until the mixture looks like wet sand then press it firmly and evenly across the bottom of the pan using your hands or the bottom of a glass for a compact base.
- Melt Marshmallows:
- Place three cups mini marshmallows and two tablespoons butter in a microwave-safe bowl. Heat in twenty second bursts stirring each time until the marshmallows are gooey and fully melted. This creates the signature stretchy marshmallow layer. Quickly spread this evenly over your graham cracker base. Let it sit five minutes to cool just slightly.
- Prepare Chocolate Layer:
- Combine chocolate chips and heavy cream in another microwave-safe bowl. Microwave in twenty second intervals stirring each time until the chocolate melts and the mixture is silky smooth. Pour this chocolate over the marshmallow layer then use a spatula to spread it edge to edge.
- Add the Toppings:
- While chocolate is still soft sprinkle extra mini marshmallows graham cracker pieces and optional chocolate chips evenly on top. Gently press them down so they stick into the glossy surface.
- Chill and Slice:
- Place the pan in the refrigerator for at least one hour so everything sets and holds together. Once chilled lift the bars from the pan using the parchment overhang and slice into squares with a sharp knife.

Graham crackers really make these bars taste like authentic s'mores Their honey and whole wheat notes create a nostalgic flavor and every time I break up toppings with my kids we all joke about sneaking bites while we work.
Storage Tips
Store these bars in an airtight container in the fridge for up to five days They are best eaten cold as the chocolate and marshmallow layers stay firm If you want softer bars let them sit at room temperature for fifteen minutes before serving
Ingredient Substitutions
You can use digestive biscuits instead of graham crackers for a European spin For the chocolate layer swap semisweet chips with milk chocolate if you like it sweeter Vegetarian marshmallows or a spreadable vegan marshmallow cream are great picks for plant-based diets
Serving Suggestions
