Some recipes exist purely to make people happy. No nutritional agenda, no complicated technique, no story about how it changed my life. Just pure, unapologetic joy in bar form. These s’mores rice krispie treats are exactly that — and I say that as someone who takes food pretty seriously.

The idea came to me when I wanted that classic campfire s’mores experience without actually having to go outside and deal with a fire. Because honestly, sometimes you just want the chocolate and the marshmallow and the graham cracker situation without the smoke in your eyes and the mosquitoes. You know what I mean? So I took everything I love about s’mores and folded it into the most nostalgic no-bake treat I know, and the result was genuinely better than I expected.

What you get is this golden, chewy, gooey bar loaded with mini marshmallows, golden graham cracker pieces, and chunks of melty chocolate in every single bite. Twenty minutes, one pot, zero oven required. Let’s get into it.

Why you’ll love this recipe

  • All the flavor of a campfire s’more in a chewy, gooey no-bake bar
  • Ready in 20 minutes with zero oven time required
  • Uses simple ingredients you can find at any grocery store
  • The combination of textures — chewy, crunchy, melty — is genuinely addictive
  • Perfect for kids, parties, bake sales, or just a Tuesday when you need something good
  • Stores well so you can make a big batch and snack all week

Ingredients and key notes

For the rice krispie base:

  • 4 tablespoons unsalted butter — use real butter here, not margarine; it makes a noticeable difference in flavor
  • 1 bag (10 oz) large marshmallows — these melt down into the gooey binding that holds everything together
  • 1/2 teaspoon vanilla extract — just a touch, but it rounds out the flavor beautifully
  • 3 cups rice krispie cereal — the classic base that gives you that signature chewy crunch
  • 1 1/2 cups golden graham cracker cereal or crushed graham crackers — this is what brings the campfire s’mores flavor in
  • 1 cup mini marshmallows — these go in at the end and stay soft and pillowy in the finished bars

For the mix-ins:

  • 1 cup milk chocolate chips or roughly chopped milk chocolate bar — chocolate chunks give you those gorgeous melty pockets throughout
  • Extra mini marshmallows and graham cracker pieces for topping — optional but highly recommended for presentation

Key notes:

  • Do not use margarine or butter substitutes. Real butter gives you that rich, slightly toasted flavor as it melts and browns slightly before the marshmallows go in.
  • Low and slow is the rule here. Melt everything over low heat and resist the urge to crank it up. High heat scorches the marshmallows and makes your bars tough and dry instead of soft and gooey.
  • Add the chocolate chips and extra mini marshmallows off the heat after you have mixed everything together. If the mixture is too hot when the chocolate goes in, it melts completely into the bars instead of staying in distinct, visible chunks.
  • Work fast once everything is combined. Rice krispie mixtures set quickly and become difficult to press into the pan if you let them sit too long.
  • Grease your hands or the spatula you use to press the bars down. The mixture is extremely sticky and greased hands make the whole process so much easier.

Step-by-step instructions

Step 1: Prepare your pan

Line a 9×13 inch baking pan with parchment paper and spray it lightly with cooking spray. The parchment overhang on the sides will make it easy to lift the whole slab out cleanly once the bars are set. Set the pan aside.

Step 2: Melt the butter

In a large heavy bottomed pot or Dutch oven, melt the butter over low heat. Let it melt slowly and swirl the pan occasionally. You want it fully melted and just starting to take on a very light golden color — this adds a subtle nutty depth to the bars that makes them taste even better.

Step 3: Melt the marshmallows

Add the large marshmallows to the melted butter and stir continuously over low heat until completely melted and smooth. This takes about 3 to 4 minutes. Keep stirring the whole time — marshmallows can scorch on the bottom if left sitting still in a hot pot. Once fully melted, remove the pot from the heat entirely.

Step 4: Add vanilla

Stir the vanilla extract into the melted marshmallow mixture. It takes about 10 seconds but it makes a real difference in the final flavor. Do not skip it.

Step 5: Add the cereals

Working quickly, add the rice krispie cereal and graham cracker cereal to the pot. Fold everything together with a rubber spatula until the cereal is fully coated in the marshmallow mixture. Move fast — the mixture starts to set as it cools.

Step 6: Add the chocolate and mini marshmallows

Once the cereal is fully coated, add the chocolate chips and mini marshmallows. Fold them in gently with just a few strokes. You want the chocolate to stay in chunks and the mini marshmallows to stay whole and visible — not fully melted into the mixture. A few gentle folds is all you need here.

Step 7: Press into the pan

Transfer the mixture into your prepared pan. Lightly grease your hands or a spatula and press the mixture down firmly and evenly. Do not press too hard — you want the bars to be compact enough to hold their shape but still light and chewy, not dense and compressed.

Step 8: Add toppings

Immediately press a handful of extra mini marshmallows and a few graham cracker pieces onto the top surface of the bars while everything is still warm and sticky. This gives them that beautiful s’mores look and makes it clear exactly what you are about to eat.

Step 9: Set and slice

Let the bars sit at room temperature for at least 15 minutes until fully set. Once set, use the parchment overhang to lift the entire slab out of the pan onto a cutting board. Slice into squares or rectangles with a sharp knife. A lightly greased knife gives you cleaner cuts.

Serving suggestions

These bars are fantastic on their own but here are a few ways to make them even more fun to serve:

  • Stack a few bars on a plate and serve them at your next cookout or backyard gathering — they fit right in with the outdoor, campfire theme
  • Warm individual bars in the microwave for 8 to 10 seconds before serving to bring back that fresh, gooey, just-made texture
  • Serve alongside a scoop of vanilla ice cream for a ridiculously good dessert combination — the warm chewy bar against cold ice cream is hard to beat
  • Cut them into smaller bite-size pieces and serve on a platter at a kids party — they disappear in minutes
  • Wrap individual bars in parchment paper and tie with twine for a thoughtful homemade gift or bake sale contribution
  • Pair with a hot mug of hot chocolate on a cold evening for the ultimate cozy treat that tastes like camping without leaving your couch

Storage tips

Room temperature: Store in an airtight container at room temperature for up to 3 days. Place sheets of parchment paper between layers to prevent the bars from sticking together. They are at their absolute best on day one when the texture is perfectly chewy and the chocolate is still a little soft.

Refrigerator: You can store these in the fridge for up to 5 days but be aware that cold temperatures make rice krispie treats harder and less chewy. If you refrigerate them, let them come back to room temperature for about 10 minutes before eating or warm them briefly in the microwave.

Freezer: These freeze well. Wrap individual bars tightly in plastic wrap and place in a freezer safe bag or container. Freeze for up to 6 weeks. Thaw at room temperature for about 20 minutes before serving. The texture holds up surprisingly well after freezing.

Cutting tip: If the bars have set too firm by the time you go to cut them, warm your knife under hot water, wipe it dry, and slice. The warmth helps the knife glide through cleanly without dragging or cracking the bars.

Before you go

There are fancy recipes and there are recipes that just make people genuinely happy the moment they take a bite. These s’mores rice krispie treats fall very firmly into the second category — and there is absolutely nothing wrong with that.

Twenty minutes, one pot, and a handful of ingredients that most people already have somewhere in their pantry. That is all it takes to put something on the table that makes everyone reach for seconds before they have even finished their first bar.

Make these for your next gathering, make them for your kids after school, or make them for yourself on a quiet evening when you just want something good and simple. However you enjoy them, I hope they bring a little of that campfire magic into your kitchen.

With gratitude, Kip

Frequently Asked Questions

Expand All:

Can I use fresh marshmallows instead of a bag of large marshmallows?

Yes, any standard marshmallows work for melting down into the base. Large marshmallows, regular sized marshmallows, or even a jar of marshmallow fluff all melt down the same way. If you use marshmallow fluff, use about 1 and a half cups as a substitute for the bag of marshmallows. The mini marshmallows you fold in at the end should stay as mini marshmallows since they are meant to remain whole and visible in the finished bars.

Why are my rice krispie treats hard instead of chewy?

This almost always comes down to heat. Cooking the marshmallows over heat that is too high makes the sugar in them seize up and turn the bars tough and hard once they cool. Always melt your marshmallows over low heat and stir constantly. Also make sure you are pressing the mixture into the pan gently — compressing it too firmly squeezes out the air and makes the bars dense.

Can I use dark chocolate instead of milk chocolate?

Absolutely. Dark chocolate actually works beautifully here if you prefer a less sweet bar. The slight bitterness of dark chocolate plays really well against the sweetness of the marshmallow and graham cracker. You can also use a mix of milk and dark chocolate chips for a more complex flavor. White chocolate chips are another fun option if you want to mix things up.

Can I make these gluten free?

Yes with a couple of swaps. Standard rice krispie cereal is not always certified gluten free so look for a certified gluten free rice cereal brand. Replace the graham cracker cereal with certified gluten free graham crackers or a gluten free honey cereal. Everything else in the recipe is naturally gluten free. The result tastes essentially identical.

How do I keep the bars from sticking to everything?

Grease your hands, your spatula, and your knife before each use. A light spray of cooking spray on your hands before pressing the mixture into the pan is a game changer. For cutting, run your knife under warm water and wipe it dry before each cut. Lining the pan generously with parchment paper before you start means the bars lift out cleanly every time.

Can I add anything else to customize these bars?

Definitely. A drizzle of melted chocolate over the top of the set bars looks incredible and adds extra chocolate flavor. A sprinkle of flaky sea salt over the chocolate drizzle is a combination I highly recommend. You can also add a layer of peanut butter mixed into the marshmallow base before adding the cereal if you want a peanut butter s'mores version. The base recipe is very flexible and handles additions well.
