This Rice Krispie S'mores Pinwheels recipe transforms a campfire classic into a show-stopping dessert that’s perfect for parties or cozy nights in.
The magic happens when crispy Rice Krispie clusters get wrapped in gooey marshmallow and chocolate swirls, creating a dessert that’s as fun to make as it is to eat. I developed this recipe after craving a no-bake treat that felt special enough for guests but simple enough for a weeknight.
The base starts with a buttery graham cracker crust, layered with melted chocolate and toasted marshmallows for that signature s'mores flavor.

For extra indulgence, try adding crushed graham crackers or a swirl of peanut butter to the filling. These pinwheels are perfect for holidays, potlucks, or just because. Let’s get rolling!
Ingredients for rice krispie s'mores pinwheels
Twelve fun ingredients for a dessert that's all about playful textures and nostalgic flavors.
| Ingredient | Amount | Notes |
|---|---|---|
| Rice Krispies Cereal 🍪 | 4 cups | Original flavor, lightly toasted |
| Large Marshmallows 🧸 | 2 cups | Mini marshmallows work too |
| Unsalted Butter 🧈 | ½ cup | Melted, full-fat preferred |
| Graham Crackers 🍪 | 1 ½ cups | Crushed into fine crumbs |
| Semi-Sweet Chocolate Chips 🍫 | 1 ½ cups | High-quality for best melt |
| Powdered Sugar 🍚 | ¼ cup | For dusting and filling |
| Vanilla Extract 🌿 | 1 tsp | Pure, high-quality preferred |
| Salted Peanuts 🥜 | ½ cup | Chopped, optional topping |
| Whipped Cream 🍦 | ½ cup | Stable, store-bought preferred |
| Peanut Butter 🥜 | ¼ cup | Creamy, for optional swirl |
| Milk 🥛 | ¼ cup | For marshmallow melting |
| Dark Chocolate Bars 🍫 | 2 oz | Melted, for optional drizzle |
The Rice Krispies are the star here—Kellogg's original has that perfect crunch. Trader Joe's sells them in bulk if you want to stock up, but any brand works. For the marshmallows, Kraft Jet-Puffed or Dandies melt beautifully. The butter should be unsalted—salted can make the filling taste flat. Pro tip: crush the graham crackers in a food processor for ultra-fine crumbs. If you're feeling fancy, grab a silk screen to pipe the marshmallow filling into neat swirls.
No powdered sugar? Confectioners' sugar is the same thing—just make sure it's sifted first. Short on marshmallows? Mini marshmallows double the recipe work perfectly. Want to skip the peanut butter? A dollop of Nutella or extra chocolate chips adds richness. The whipped cream can be homemade (whip heavy cream + powdered sugar), but Reddi-wip saves time. For the chocolate drizzle, Ghirardelli squares melt smoother than chips. And if you're making these for kids? Skip the nuts entirely—just add extra chocolate.
These pinwheels keep surprisingly well—3 days in an airtight container at room temp, or 1 week in the fridge. For parties, assemble ahead and slice just before serving. The filling firms up slightly in the fridge, so let them sit at room temp for 10 minutes before slicing. Freezing isn't recommended—they get too soft. If you make extras, wrap individually in parchment for easy gifting. The powdered sugar dusting? Do it right before serving, or it'll clump.

Step-by-step instructions for Rice Krispie s'mores pinwheels
Here's how to create these magical pinwheels with layers of crunch, gooey marshmallow, and chocolate goodness.
Melt Marshmallows and Butter for the Binding Glue
In a large microwave-safe bowl, combine the 2 cups large marshmallows and 0.5 cup unsalted butter. Microwave in 30-second bursts, stirring vigorously between each interval, until completely melted and smooth. You're aiming for a thick, syrupy consistency that will hold everything together beautifully.
The mixture should be slightly thicker than warm honey—if it's too runny, microwave for another 10 seconds. Here's the thing: this is your binding agent, so it needs to be just right. Too thin and your pinwheels will fall apart; too thick and they'll be dense. Stir in the 1 teaspoon vanilla extract and 0.25 cup milk until fully incorporated. This creates the perfect gooey base that'll make your pinwheels irresistibly sticky.
Mix Crunchy Base with Marshmallow Mixture
Add the 4 cups rice krispies cereal and 1.5 cups graham cracker crumbs to the marshmallow mixture. Stir gently but thoroughly until every cereal piece is coated in that glossy marshmallow butter. You want to see golden cereal pieces peeking through the marshmallow glaze—this is what gives those perfect s'mores flavors.
Don't worry if it looks messy—this is supposed to be a sticky situation. Transfer the mixture to a 9x13-inch baking dish and spread it out evenly, pressing down gently with a spatula. This ensures even thickness when you roll it later. The mixture should be about ¼-inch thick—if it's too thick, it won't roll properly.
Create the Chocolate Swirl Layer
In a separate microwave-safe bowl, melt the 1.5 cups semi-sweet chocolate chips and 2 oz dark chocolate bars together using 30-second bursts, stirring between each. Once fully melted, whisk in the 0.25 cup peanut butter until smooth. This creates a rich, decadent layer that'll be the star of your pinwheels.
Spread the chocolate mixture evenly over the marshmallow-cereal layer in the baking dish. Use a spatula to create swirls—this is where the magic happens. The contrast between the chocolate and marshmallow will make each bite a flavor explosion. For extra decadence, sprinkle the 0.5 cup salted peanuts evenly over the chocolate layer before it sets.
Roll and Cut into Perfect Pinwheels
Dust a clean work surface generously with 0.25 cup powdered sugar—this prevents sticking. Carefully invert the baking dish onto the prepared surface. Lift the dish off and gently roll the entire mixture into a log using a piece of parchment paper. Apply light but firm pressure to keep it compact.
Chill the log in the refrigerator for 30 minutes until firm enough to slice. Using a serrated knife, cut the log into 12 equal pinwheels (about 1-inch thick each). Here's the pro tip: dip your knife in hot water between cuts to prevent sticking and get clean slices every time.
Assemble and Decorate Your Pinwheels
Place each pinwheel on a serving platter and top with a dollop of 0.5 cup whipped cream. The contrast between the warm pinwheel and cool whipped cream is pure perfection. For an extra touch, drizzle with any remaining melted chocolate from your bowl—this creates that classic s'mores look.
Serve immediately while the chocolate is still slightly warm and gooey. These pinwheels are best enjoyed fresh out of the fridge—each bite delivers that perfect balance of crunchy rice krispies, gooey marshmallow, rich chocolate, and salty peanuts. Store any leftovers in an airtight container in the fridge for up to 3 days, though they won't last that long!
Pro Tips For Making Rice Krispie S'Mores Pinwheels
- Melt Marshmallows Low and Slow: I learned this the hard way—blasting them on high turns them rubbery. Use medium-low heat and stir constantly with a wooden spoon, breaking them into chunks as they soften. If they start golden on the edges, you’ve gone too far.
- Crush Graham Crackers Coarse: Skip the food processor for this one. Use a rolling pin and a heavy pan to crush graham crackers into uneven pieces—think pebble-sized, not powder. This gives the pinwheels real texture instead of a sad, crumbly mess.
- Butter the Pan First: Grease your baking sheet with butter (not oil) before assembling pinwheels. The butter melts when they bake, creating a subtle crispness along the edges—like a mini campfire toast. Trust me, it makes a real difference.
- Chill Before Rolling: Let the marshmallow-butter mix cool slightly before spreading it on the graham cracker layer. Warm goo slips everywhere, and your pinwheels end up lopsided. A 5-minute break in the fridge keeps things tidy—and your kitchen less sticky.
Perfect pairings for this rice krispie s'mores pinwheels
Dessert Drink Pairings
These pinwheels are perfect with a hot chocolate bar—set out mini marshmallows, whipped cream, and chocolate shavings for guests to customize their drinks. I love using Ghirardelli hot cocoa mix for its rich, velvety texture that complements the dessert's flavors.
For a grown-up twist, add a splash of Baileys Irish Cream to warm milk. 🍫
Creamy Coffee Match
Pair your pinwheels with a cappuccino or latte—the espresso's bitterness cuts through the sweetness beautifully. For an extra treat, top your coffee with a sprinkle of cocoa powder or a drizzle of caramel sauce.
A vanilla chai latte also works wonderfully, as the warm spices echo the vanilla in the pinwheels.
Fruity Contrast Options
For a refreshing contrast, serve with strawberry shortcake or raspberry sorbet—the tartness balances the sweetness. I often pair them with a sparkling peach iced tea for a light, bubbly accompaniment. The effervescence cleanses the palate between bites of rich pinwheel.
Boozy Upgrades
Transform your dessert into a party favorite by pairing with Baileys-spiked milkshakes or bourbon caramel sauce. For a sophisticated touch, serve with a chocolate martini—the deep cocoa flavor enhances the pinwheel's chocolate-marshmallow combo. Always serve alcohol responsibly and in moderation.
Seasonal Beverage Ideas
In summer, pair with mango lassi or lemonade—the cool, citrusy flavors refresh after a rich dessert. For fall, a pumpkin spice latte adds warmth that complements the marshmallow's sweetness. In winter, mulled wine with cinnamon sticks creates a cozy, festive pairing that feels like a campfire treat. ✨

Frequently asked questions
Can I make these pinwheels with mini marshmallows instead of large ones?
Mini marshmallows work perfectly and actually require less melting time. Use 4 cups mini marshmallows instead of 2 cups large marshmallows to maintain the same gooey texture. The smaller size melts faster, so watch closely in 20-second bursts to avoid overcooking.
How do I prevent the pinwheels from falling apart when slicing?
Chill the rolled log for the full 30 minutes before slicing—this is crucial for stability. Use a serrated knife and dip it in hot water between cuts to prevent sticking. Also, make sure your marshmallow mixture isn't too runny when assembling the layers.
Can I make these pinwheels ahead of time?
Yes, but with a few adjustments. Assemble the pinwheels and store them in an airtight container in the fridge for up to 3 days. Let them sit at room temperature for 10 minutes before serving to restore the gooey texture. For parties, slice them just before serving to keep the edges crisp.
What's the best way to add peanut butter to the recipe?
Mix the 0.25 cup peanut butter directly into the melted chocolate layer before spreading it over the marshmallow mixture. For extra decadence, spread a thin layer of peanut butter on the graham cracker crust before adding the marshmallow mixture. This creates a peanut butter "sandwich" in each bite!
Why did my marshmallow mixture turn grainy?
This usually happens when marshmallows overcook or aren't stirred properly. Microwave in 30-second bursts and stir vigorously between each interval. If it starts to look grainy, add a splash of milk or cream to smooth it out. Also, make sure your butter is fully melted before combining with marshmallows.
