S’mores Rice Krispies Treats Recipe

My gooey S’mores Rice Krispies Treats are a playful twist on a beloved childhood classic. Crispy cereal, melted marshmallows, graham cracker pieces, and chopped chocolate combine into an easy no‑bake dessert that’s perfect for cookouts, parties, after‑school snacks, and holidays.

Rice Krispies treats are a family favorite for good reason: the contrast of ooey‑gooey marshmallow and crunchy cereal is irresistible. This version layers the classic flavors of s’mores—graham crackers, chocolate, and marshmallows—into every bite, delivering that campfire taste without needing a fire or skewers.

To build the s’mores flavor I layer chopped chocolate bars, mini marshmallows, and broken graham crackers into the cereal mixture. The result is a chewy, flavorful bar with pockets of melted chocolate and toasted marshmallow texture.

Ingredients For S’mores Rice Krispies Treats

These ingredients combine traditional s’mores elements with crisp cereal for an easy, nostalgic dessert.

• 6 tablespoons unsalted butter — unsalted gives you control over the final seasoning.
• 12 ounce bag jumbo marshmallows — melted with the butter to bind the bars.
• 1 teaspoon vanilla extract — adds warmth and depth.
• 6 cups Rice Krispies cereal — provides the signature crunch.
• 2 cups graham crackers, broken — adds authentic s’mores texture and flavor.
• 2 cups mini marshmallows — for marshmallow pockets throughout the bars.
• 3 Hershey’s chocolate bars, chopped — or substitute chocolate chips or another bar you prefer.

How To Make S’mores Rice Krispies Treats

1. Line a 9 x 9 baking dish with parchment paper and lightly spray the parchment with non‑stick cooking spray.
2. In a large pot over medium‑low heat, melt the butter. Add the jumbo marshmallows and stir constantly until fully melted and smooth.
3. Remove the pot from heat and stir in the vanilla extract. Add the Rice Krispies cereal, 1 cup of the mini marshmallows, and the broken graham crackers, stirring until everything is evenly coated.
4. Press half of the cereal mixture gently into the prepared baking dish using a parchment‑lined spatula or lightly greased hands. Avoid pressing too firmly—gentle compression keeps the bars tender.
5. Scatter half of the chopped chocolate and 1/2 cup of mini marshmallows evenly over the first layer.
6. Top with the remaining cereal mixture and press lightly to form the top layer. Sprinkle the remaining chopped chocolate, the remaining 1/2 cup mini marshmallows, and a few extra graham cracker pieces across the surface.
7. Let the pan rest at room temperature for about 30 minutes to set before slicing. Use the parchment to lift the slab from the dish and cut into squares with a sharp knife. For cleaner cuts, wipe the knife between slices or lightly grease it with butter.

Heather’s Recipe Tips

• Melt over low heat: Keep the heat low and stir constantly so marshmallows melt smoothly without scorching.
• Use fresh marshmallows: Fresh marshmallows melt more evenly for a silky binder.
• Don’t over‑press: Press gently so bars remain chewy instead of dense and hard.
• Allow proper rest time: Let bars set for about 30 minutes for the best texture and easier slicing.

Variations

Small substitutions make big flavor differences—try one of these variations to suit your taste.

Chocolate: Swap chopped Hershey’s bars for chocolate chips, dark chocolate, or a cookies‑and‑cream bar for a different profile.

Golden Grahams boost: Replace 2 cups of Rice Krispies with Golden Grahams to intensify the graham flavor.

Peanut butter s’mores: Stir 2–3 tablespoons of peanut butter into the melted marshmallow for a nutty twist.

Sea salt finish: A light sprinkle of flaky sea salt on top balances the sweetness and enhances chocolate flavor.

Storage Instructions

Store leftover s’mores Rice Krispies treats in an airtight container at room temperature for 3–4 days. Refrigeration tends to dry them out, so avoid the fridge. To freeze, wrap individual bars in plastic wrap and place them in a sealed bag; thaw at room temperature before serving.

Common Questions

• Why are my bars hard? High heat when melting marshmallows or pressing the mixture too firmly can make bars dense and hard. Use low heat and press gently.
• Can I use only mini marshmallows? Yes—substitute a full bag of mini marshmallows if you prefer; they will melt, though jumbo marshmallows are often easier to work with for the melted base.
• Can I toast the marshmallows? For a campfire flavor, briefly toast the mini marshmallows placed on top under the oven broiler until lightly browned. Watch carefully to prevent burning.
