This Rice Krispie s'mores pinwheels recipe transforms a childhood classic into a showstopping dessert that’s equal parts nostalgic and impressive.
The secret lies in layers of crispy Rice Krispie treats, melted marshmallow fluff, and rich chocolate swirls—all rolled into golden pinwheels that slice cleanly and taste like a campfire in every bite.
I’ve perfected the technique to ensure gooey centers and crisp edges, with just the right amount of chilling time to hold its shape when sliced.
The magic happens in the rolling and baking: a thin layer of melted chocolate between the Rice Krispie dough and marshmallow filling creates that signature s’mores flavor without falling apart. These pinwheels are foolproof for gatherings—no one will believe they’re as easy to make as they are delicious.
Plus, the versatility lets you customize with peanut butter swirls or white chocolate for a grown-up twist.
What you’ll end up with is a dessert that looks like it came from a bakery but requires just a few simple ingredients and a little patience. The marshmallow stays soft and gooey, the chocolate adds depth, and the graham cracker crumbs on top give that classic s’mores texture.
Serve warm with a scoop of vanilla ice cream for the ultimate indulgence.
For extra flair, drizzle melted chocolate over the top or sprinkle crushed graham crackers before baking. These pinwheels are perfect for parties, potlucks, or even a cozy night in—just don’t blame me if they disappear before the first slice is served. Let’s get baking!
Ingredients for rice krispie s'mores pinwheels
Gather these nostalgic ingredients for pinwheels that taste like campfire magic.

The Rice Krispies are the star here—original flavor makes all the difference. Trader Joe's or Costco sell bulk bags that save money for big batches. For the marshmallows, mini size gives you that perfect bite, but regular works if that's what you've got. Chocolate chips should be high-quality—Ghirardelli or Ghirardelli baking chips melt smoothly. Graham cracker crumbs? Crush them yourself in a food processor for that perfect texture—pre-packaged crumbs get gummy when melted.
No white chocolate? Substitute with extra semi-sweet—just melt it separately. Skipping peanut butter? Add a pinch of cinnamon to the marshmallow filling for warmth. The butter needs to be fully melted but not hot—microwave in 20-second bursts to avoid burning. For the dough, if you don't have vanilla extract, vanilla sugar at half the amount works in a pinch. The eggs should be room temp—cold eggs make the dough tough. Pro tip: if your dough feels sticky, add a splash more powdered sugar.
Store the unbaked pinwheels in the fridge for up to 24 hours—they'll hold their shape better after chilling. Baked pinwheels keep for 3 days in an airtight container at room temp, but they're best served warm. Freeze baked pinwheels for 1 month—reheat in a 300°F oven for 5-10 minutes. I like to make a double batch and freeze half—perfect for last-minute parties. The graham cracker crumbs on top add that campfire crunch, so don't skip them!
Why You'll Love This Recipe
- Five-Ingredient Magic: I swear by this—just cereal, butter, marshmallows, chocolate, and graham crumbs. That’s it. No fancy equipment, no stress, and no waiting for anything to thaw or preheat. Honestly, I’ve made these while standing at the counter, one hand stirring, the other holding a kid who “needs help.”
- Crunchy-Creamy Bliss: The contrast is what gets me. That buttery Rice Krispie layer stays crisp even when rolled, while the melted chocolate and marshmallow center oozes with every bite. Here’s what sold me: the graham cracker crumbs add this perfect sandy texture that makes it feel like a grown-up dessert, not just a kid’s snack.
- Campfire Vibes Anywhere: Between us, these taste exactly like s’mores—just without the fire, the skewers, or the singed marshmallow fingers. I’ve served them at summer BBQs, holiday parties, and even as a “fancy” dessert when friends over for game night. (Yes, even on a Tuesday night.)
- Zero-Waste Win: Make a double batch, roll them up, and store them in an airtight container for up to a week. They don’t dry out, they don’t need reheating, and honestly? Half the time, they disappear faster than I can pack them away. Budget-friendly too—uses pantry staples I already had, and the leftovers? Always gone by Thursday.
Step-by-step instructions for Rice Krispie s'mores pinwheels
Here's how to make these gooey, swirled treats that taste like summer in every bite.
Melt Butter and Chocolate for the Binding Base
In a large microwave-safe bowl, melt the 0.5 cup unsalted butter in 30-second intervals, stirring between each, until fully liquid. Add the 1 cup semi-sweet chocolate chips and microwave again in 20-second bursts, stirring until completely smooth. You'll know it's ready when the mixture looks glossy and shiny with no streaks of unmelted chocolate.
Remove from microwave and stir in the 1 tsp vanilla extract and 0.5 cup powdered sugar until fully combined. This mixture will be the glue that holds everything together, so make sure it's completely smooth—any lumps will show up in your final pinwheels. Let it cool slightly for 2-3 minutes while you prepare the next components.
Mix the Dry Ingredients and Create the Swirl
In a separate large bowl, combine the 6 cups rice krispies cereal, 1.5 cups graham cracker crumbs, and 3 cups mini marshmallows. Gently fold these together with a spatula until evenly distributed. The marshmallows will start to soften slightly, which is perfect for that gooey texture we're after.
For the swirl variation, melt the 0.5 cup white chocolate chips and 0.25 cup peanut butter together in another microwave-safe bowl using 20-second intervals, stirring until smooth. This mixture will create those beautiful chocolate-peanut butter ribbons when we roll the dough. Keep this separate until we're ready to assemble the pinwheels.
Combine Wet and Dry Ingredients
Add the 2 whole large eggs to the melted butter-chocolate mixture and whisk vigorously for 1 minute until fully incorporated. The eggs will help bind everything together and create that light, airy texture. Pour this wet mixture over the dry ingredients and gently fold everything together with a spatula until just combined.
Here's where it gets fun - fold in half of the melted white chocolate-peanut butter mixture, reserving the rest for the swirl. Be careful not to overmix - we want to maintain that light, crispy texture of the rice krispies. The dough should be sticky but manageable. If it's too dry, add 1 teaspoon of milk to help bind it.
Roll, Swirl, and Cut the Pinwheels
Line a large baking sheet with parchment paper and lightly grease it with butter. Transfer the dough to the prepared sheet and spread it out into a 12x16-inch rectangle, about ¼-inch thick. Use an offset spatula to smooth the top and create even edges.
Drizzle the reserved white chocolate-peanut butter mixture in a zigzag pattern across the dough. Using a spatula, gently spread the mixture into thin ribbons, creating those beautiful swirls. Then, using a sharp knife, cut the dough into 12 equal rectangles (about 4x3 inches each).
Bake Until Golden and Set
Preheat your oven to 350°F and bake the pinwheels for 12-15 minutes until the edges are golden brown and the centers look just set. They should be firm to the touch but still slightly soft in the middle - this ensures that gooey texture we all love.
Let the pinwheels cool on the baking sheet for 10 minutes before transferring to a wire rack. While they cool, sprinkle the tops with 0.25 cup crushed graham crackers for that extra crunch. Serve warm with a scoop of 1 cup vanilla ice cream on the side for the ultimate s'mores experience!
Pro Tips For Making Rice Krispie S'Mores Pinwheels
- Melt Marshmallows Slowly: I learned this the hard way—dumping mini marshmallows into butter at full heat turns them into sticky globs before the butter even melts. Use low-medium heat and stir constantly with a wooden spoon, breaking up clumps as they soften. If they start browning too fast, pull the pan off the heat for 10 seconds and let the residual heat finish the job.
- Toast Graham Crackers First: Crunchy graham cracker crumbs make all the difference, but store-bought crumbs lose their texture when mixed into melted chocolate. Pulse 1 cup of graham crackers in a food processor until finely ground, then toast them in a dry pan over medium-low heat for 2-3 minutes, stirring constantly, until they smell toasty. Let cool completely before mixing—this prevents the filling from getting soggy.
- Chill the Mixture Fully: Skipping this step is how you end up with a greasy, unrollable mess. After mixing everything together, spread the Rice Krispie-s’mores filling onto parchment paper in an even layer, then refrigerate for at least 30 minutes (or up to 2 hours). The butter needs to firm up enough to hold shape when rolled—trust me, your pinwheels will thank you.
- Use Extra Butter for Binding: The recipe might call for a specific amount, but Rice Krispies are thirsty. If your mixture feels dry or crumbly after adding all the marshmallow-butter mix, add 1-2 extra tablespoons of melted butter (just enough to make it stick together when pressed). Too little butter = pinwheels that fall apart; too much = gooey, but this is the sweet spot.
Storing and reheating your leftovers
Fridge Storage Tips
Store your unbaked pinwheels on a parchment-lined tray in the fridge for up to 24 hours before baking. The cold helps them hold their shape perfectly when sliced. For baked pinwheels, transfer them to an airtight container with parchment paper between layers to prevent sticking.
They’ll stay fresh for 3 days at room temperature, but I always serve them warm for that gooey magic. 🧊
Freezer Prep
Freeze unbaked pinwheels for up to 1 month by wrapping them tightly in plastic wrap, then placing them in a freezer bag with all the air squeezed out. For baked pinwheels, let them cool completely before freezing.
Reheat in a 300°F oven for 5-10 minutes until warmed through. I love making a double batch and freezing half—they’re perfect for last-minute parties! ❄️
Reheating Methods
For the best texture, reheat pinwheels in a 350°F oven for 3-5 minutes until warm and slightly crispy. If you’re short on time, use the microwave on 50% power for 20-30 seconds, then let them sit for 1 minute to redistribute the gooey centers.
Avoid reheating in the toaster—it’ll dry out the marshmallow filling. 🔥
Serving Warm
Serve pinwheels warm straight from the oven with a scoop of vanilla ice cream for the ultimate s’mores experience. The contrast of cold ice cream and warm pinwheels is pure magic.
For extra flair, drizzle with melted chocolate or sprinkle with crushed graham crackers right before serving. They’re even better the second time around—trust me! 🍦
Make-Ahead Pro Tips
Prep the dough ahead of time and store it in the fridge for up to 24 hours before rolling and cutting. This saves you last-minute stress. If you’re baking for a crowd, assemble the pinwheels on a tray, cover with foil, and refrigerate until ready to bake.
The flavors deepen overnight, making them even more irresistible. 💡

Frequently asked questions
Can I make these pinwheels without peanut butter?
Skip the peanut butter and use extra 0.5 cup white chocolate chips for a pure chocolate swirl, or add 1 teaspoon cinnamon to the marshmallow filling for warmth. You could also try caramel or salted caramel chips for a gourmet twist that still keeps the classic s'mores vibe.
Why are my pinwheels falling apart when I slice them?
This usually happens if the dough wasn't chilled long enough before cutting or if you didn't use enough binding ingredients. Let the rolled dough rest in the fridge for 30 minutes before slicing, and make sure your butter-chocolate mixture is fully cooled before combining with the dry ingredients. If they still crumble, add 1 extra egg to your wet mixture for better adhesion.
How do I get the swirl to look perfect?
Use a sharp knife or offset spatula to create thin, even ribbons of the swirl mixture. Drizzle in a zigzag pattern and spread gently with the back of the spatula—don't press too hard or the dough will tear. For extra flair, chill the rolled dough for 15 minutes before cutting to help the swirls hold their shape when sliced.
Can I use regular marshmallows instead of mini?
Yes, but you'll need to reduce the quantity to 2 cups instead of 3 cups since regular marshmallows are larger. They'll create bigger pockets of gooey goodness, but the texture will be slightly less uniform. For best results, lightly crush the regular marshmallows with a fork before mixing to mimic the mini marshmallow consistency.
What's the best way to transport these to a party?
Cool the baked pinwheels completely, then arrange them in a single layer on a parchment-lined tray. Cover tightly with plastic wrap and place in a cooling rack inside a box for easy transport. They'll stay fresh for 4-6 hours at room temperature. For longer trips, keep them in an insulated bag with an ice pack to maintain their gooey texture.
