Ingredients

The foundation of great s’mores bars is a buttery graham‑cracker crust that holds everything together, while the heart of the bar is a luscious blend of chocolate and marshmallows that stays soft and gooey after baking. A light dusting of sea salt and a final broil give the top a caramelized crunch that mimics the toasty marshmallow you love from a campfire.
Crust
- 1 ½ cups graham cracker crumbs
- ¼ cup granulated sugar
- ⅓ cup unsalted butter, melted
Filling
- 12 oz semi‑sweet chocolate chips
- 1 cup mini marshmallows
- ¼ cup heavy cream
- 1 teaspoon vanilla extract
Topping & Finishing
- ½ cup marshmallow fluff or additional mini marshmallows
- Pinch of flaky sea salt (optional)
These ingredients work together to create layers of texture and flavor. The butter‑rich crust provides a crunchy base, while the cream‑infused chocolate ensures a smooth melt that embraces the marshmallows. Adding a splash of vanilla lifts the overall sweetness, and the optional sea salt amplifies the chocolate’s depth, delivering a balanced bite every time.
Step-by-Step Instructions

Preparing the Crust
Begin by preheating your oven to 350°F (175°C). In a medium bowl, combine graham cracker crumbs and granulated sugar. Drizzle in the melted butter and stir until the mixture resembles wet sand. Press the crumb mixture firmly into the bottom of a greased 9‑inch square pan, creating an even layer. Baking the crust for 8‑10 minutes creates a firm foundation that won’t soggy once the filling is added.
Making the Chocolate‑Marshmallow Filling
- Heat the Cream. Place heavy cream in a small saucepan over medium heat. Warm until just beginning to simmer—tiny bubbles will form around the edges. This temperature melts chocolate evenly without scorching.
- Combine Chocolate and Cream. Remove the pan from heat and pour the hot cream over semi‑sweet chocolate chips. Let sit for 1 minute, then stir gently until the chocolate is completely melted and the mixture is glossy.
- Incorporate Marshmallows and Vanilla. Fold in mini marshmallows and vanilla extract until evenly distributed. The marshmallows will soften slightly, creating a gooey texture that stays soft after baking.
- Spread Over Crust. Pour the chocolate‑marshmallow mixture over the pre‑baked crust, smoothing the top with a spatula. The filling should be about ½‑inch thick for even baking.
Baking and Finishing
- Bake the Bars. Return the pan to the oven and bake for 12‑15 minutes, or until the edges are set and the center is just slightly wobbly. This ensures a creamy interior without a dry center.
- Broil for Caramelization. Switch the oven to broil. Sprinkle marshmallow fluff (or additional mini marshmallows) over the top and broil for 1‑2 minutes, watching closely until the marshmallows turn golden‑brown. This step creates that signature toasted marshmallow crunch.
- Cool and Slice. Allow the bars to cool completely in the pan—about 30 minutes—so the filling sets. Once firm, lift the pan using the parchment overhang (if used) and cut into 12 even squares. A sharp knife warmed in hot water makes clean cuts.
Serving Suggestions
Serve the bars warm for maximum gooeyness, or at room temperature for a firmer bite. Pair with a scoop of vanilla ice cream, a drizzle of caramel sauce, or a dusting of powdered sugar for extra elegance. Each bite delivers the nostalgic s’mores experience in a convenient, handheld form.
Tips & Tricks
Perfecting the Recipe
Use Fresh Graham Crackers. Fresh crackers provide a crisp texture; stale ones can become soggy after baking.
Press Crust Firmly. A tightly packed crust prevents the filling from seeping through and creates a clean edge.
Don’t Over‑Bake. The filling should still have a slight jiggle when you remove it; it will continue to set while cooling.
Watch the Broil. Marshmallows brown in seconds; keep the oven door slightly ajar and stay nearby to avoid burning.
Flavor Enhancements
Add a pinch of smoked sea salt to the topping for a subtle contrast, swirl in a tablespoon of caramel sauce into the chocolate mixture before baking, or sprinkle crushed pretzel pieces for a salty crunch.
Common Mistakes to Avoid
Avoid using low‑fat chocolate—it can become grainy when melted. Also, don’t skip the cooling step; cutting too early results in crumbly bars that lose their signature gooey center.
Pro Tips
Warm Your Knife. Run a knife under hot water, dry, and slice for clean, professional‑looking cuts.
Use a Double Boiler. If you prefer a stovetop melt, a double boiler prevents scorching and yields a silkier chocolate base.
Room‑Temp Ingredients. Let the butter and cream sit at room temperature before mixing; this promotes even incorporation and a smoother batter.
Store in a Single Layer. When refrigerating, keep bars in a single layer separated by parchment to prevent sticking and preserve texture.
Variations
Ingredient Swaps
Replace semi‑sweet chocolate with dark chocolate for a richer flavor, or use white chocolate for a sweeter, milder profile. Swap mini marshmallows for toasted coconut flakes or chopped toasted pecans to add texture and a nutty note.
Dietary Adjustments
For a gluten‑free version, use certified gluten‑free graham crackers or substitute with crushed gluten‑free oat cookies. Vegan diners can replace butter with coconut oil, use dairy‑free chocolate, and choose a plant‑based marshmallow fluff or homemade agar‑based marshmallows.
Serving Suggestions
Serve bars alongside a scoop of vanilla bean ice cream, drizzle with salted caramel, or pair with fresh berries for acidity. For a festive touch, dust with powdered sugar and a sprinkle of edible gold glitter.
Storage Info
Leftover Storage
Allow the bars to cool completely, then transfer them to an airtight container. Store in the refrigerator for up to 4 days. For longer keeping, wrap individual portions in plastic wrap and freeze for up to 3 months; this preserves the chewy texture and prevents freezer burn.
Reheating Instructions
Reheat refrigerated bars in a preheated 300°F oven for 8‑10 minutes, or until the chocolate is soft and the marshmallow topping regains its glow. In the microwave, heat a single bar on medium power for 20‑30 seconds, adding a splash of milk if you prefer extra meltiness.
