Ingredients
The foundation of these bars is a buttery graham‑cracker crust that provides a sturdy yet tender base. On top, a generous layer of mini marshmallows melts into a fluffy, caramel‑kissed blanket, while two kinds of chocolate create a rich, glossy finish. A pinch of sea salt amplifies the sweetness, and optional toasted coconut adds a pleasant crunch.
Crust
- 1½ cups graham cracker crumbs
- ¼ cup unsalted butter, melted
- 2 tablespoons brown sugar
Marshmallow & Chocolate Layer
- 1 cup mini marshmallows
- ½ cup semisweet chocolate chips
- ½ cup milk chocolate chips
- ¼ teaspoon sea salt (plus a pinch for garnish)
Optional Topping
- ¼ cup toasted coconut flakes
The graham‑cracker crumbs absorb the melted butter, forming a compact crust that holds the gooey topping without crumbling. Mini marshmallows melt evenly, creating a smooth, caramel‑like layer that binds the chocolate chips together. Using both semisweet and milk chocolate gives depth and a creamy melt, while the sea salt cuts through the sweetness for a balanced finish. Optional coconut adds texture and a subtle tropical note.
Step-by-Step Instructions
Preparing the Crust
In a medium bowl, combine graham cracker crumbs, brown sugar, and the melted butter. Stir until the mixture resembles wet sand, then press it evenly into the bottom of a greased 9×13‑inch baking pan. The butter creates a golden‑brown edge as it bakes, while the sugar adds a subtle caramel flavor.
Adding the Marshmallow & Chocolate Layer
- Evenly spread marshmallows. Sprinkle the mini marshmallows over the crust, covering the surface in a single layer. This ensures they melt uniformly and create a smooth, velvety top.
- Distribute chocolate chips. Scatter the semisweet and milk chocolate chips over the marshmallows. The chips will melt into the marshmallows, forming a glossy, cohesive blanket.
- Season with salt. Sprinkle the sea salt evenly across the chocolate. The tiny crystals accentuate the sweet‑savory contrast that makes s’more so irresistible.
- Optional coconut finish. If using, scatter the toasted coconut flakes now; they will toast lightly in the oven, adding a nutty crunch.
Baking & Finishing
Preheat the oven to 350°F (175°C). Place the pan on the middle rack and bake for 12‑15 minutes, or until the edges of the crust are golden and the chocolate has fully melted, forming a smooth sheen. Remove the pan and let the bars cool for 10 minutes before cutting; this allows the topping to set, making clean squares. Finish with a light sprinkle of extra sea salt if desired, then serve warm or at room temperature.
Tips & Tricks
Perfecting the Recipe
Press firmly. Use the back of a measuring cup to compact the crust; a tight base prevents sogginess once the topping melts.
Even layer. Spread marshmallows and chocolate in a single, uniform layer to avoid pockets of unmelted chips.
Cool before cutting. Allow the bars to rest 10 minutes; this sets the chocolate and makes slicing clean.
Flavor Enhancements
Add a splash of vanilla extract to the crust for depth, or drizzle a thin layer of caramel over the top after baking. A pinch of smoked paprika in the crust adds a subtle, unexpected warmth that pairs beautifully with the sweet layers.
Common Mistakes to Avoid
Do not over‑bake; the chocolate can seize and become grainy. Also, avoid using oversized marshmallows—they melt unevenly and can create soggy spots.
Pro Tips
Use parchment paper. Lining the pan makes removal effortless and keeps the bars intact.
Room‑temperature butter. Softened butter blends more evenly with crumbs, yielding a smoother crust.
Thermometer check. If you prefer a firmer center, aim for an internal temperature of 140°F (60°C) before removing from the oven.
Store with a damp towel. Placing a lightly damp paper towel over the bars while cooling prevents the top from drying out.
Variations
Ingredient Swaps
Replace graham crackers with crushed pretzels for a salty crunch, or use crushed shortbread for an even richer base. Swap milk chocolate for white chocolate to highlight the marshmallow’s caramel notes, and add chopped toasted almonds for extra texture.
Dietary Adjustments
For a gluten‑free version, use certified gluten‑free graham‑cracker crumbs or a blend of almond flour and coconut flour. Substitute dairy‑free chocolate chips and coconut oil for the butter to keep the bars vegan, and use maple syrup instead of brown sugar for a lower‑glycemic option.
Serving Suggestions
Serve the bars warm with a scoop of vanilla ice cream for a classic s’more sundae, or drizzle with raspberry coulis for a tangy contrast. Pair with a chilled glass of milk or a robust cold brew coffee to balance the sweetness.
Storage Info
Leftover Storage
Allow the bars to cool completely, then cut and place them in an airtight container. Store in the refrigerator for up to four days. For longer keeping, wrap individual portions in plastic wrap and freeze for up to three months; this preserves both texture and flavor.
Reheating Instructions
Reheat frozen or refrigerated bars in a 300°F (150°C) oven for 8‑10 minutes, covered with foil to prevent drying. Alternatively, microwave a single bar on medium power for 20‑30 seconds, adding a splash of milk to restore meltiness.
