Ingredients for rice krispie s'mores pinwheels
These nostalgic treats blend crispy Rice Krispies with gooey marshmallow and chocolate swirls for a dessert that tastes like campfire magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Rice Krispies Cereal 🍞 | 3 cups | Lightly crushed for texture |
| Unsalted Butter 🧈 | ½ cup | Melted, full-fat preferred |
| Mini Marshmallows 🍫 | 1 ½ cups | Toasted until golden |
| Semi-Sweet Chocolate Chips 🍫 | 1 cup | Melted for swirls |
| Graham Cracker Crumbs 🍪 | 1 cup | Finely crushed, extra for rolling |
| Vanilla Extract 🌿 | 1 tsp | Pure, high-quality preferred |
| Granulated Sugar 🍚 | ¼ cup | For binding and sweetness |
| Light Corn Syrup 💧 | ¼ cup | For moisture retention |
| Heavy Whipping Cream 🥛 | ¼ cup | Whipped for fluffiness |
| Flaky Sea Salt 🧂 | ½ tsp | For finishing |
| Unsweetened Cocoa Powder 🍫 | 1 tbsp | For chocolate dusting |
| Parchment Paper 📄 | 1 sheet | For easy rolling |
The Rice Krispies are the star here—lightly crushed for texture but not too fine. Grab the classic Kellogg's brand for that perfect crunch. Mini marshmallows are a must (the full-size ones just won't toast evenly), and Trader Joe's or Marshall's have the best quality. For the chocolate, Ghirardelli chips melt beautifully, but Hershey's Special Dark adds a deeper flavor. Pro tip: toast the marshmallows in batches until they're golden—not burnt, just warm and gooey.
No mini marshmallows? Large marshmallows, roughly chopped, work in a pinch (they'll just be chunkier). Swap semi-sweet chocolate chips for dark chocolate if you prefer a richer taste, but reduce the amount to 0.75 cup to avoid overpowering. The graham cracker crumbs can be homemade (pulse graham crackers in a food processor) or store-bought—just sift them to avoid lumps. For extra decadence, fold in 1 tbsp toasted coconut flakes into the filling. And if you're feeling fancy, use white chocolate for the swirls instead of semi-sweet.
Keep the melted butter and chocolate warm in a double boiler—never microwave, or they'll seize. Roll the pinwheels tightly in parchment paper before chilling to hold their shape. Store in an airtight container with parchment between layers for up to 5 days, or freeze for 2 months. The flavors actually improve overnight as the marshmallow softens just enough to get gooey. Slice with a serrated knife for clean cuts—dip the knife in hot water between slices to prevent sticking.

Step-by-step instructions for Rice Krispie s'mores pinwheels
Here's how to transform classic s'mores into decadent pinwheels with gooey layers and crispy edges.
👨🍳 Step 1: Melt the Butter and Toast the Marshmallows
In a large saucepan over medium-low heat, melt the 0.5 cup unsalted butter until completely liquid. Add the 1.5 cups mini marshmallows and stir constantly until they begin to melt and turn golden brown—about 5-7 minutes. Real talk: this is where the magic happens, so don't walk away. You want them just golden, not burnt.
Remove the pan from heat and immediately stir in the 1 tsp vanilla extract. Let the mixture cool slightly for 2-3 minutes—it should be warm but not scorching when you handle it. This warm marshmallow mixture will bind everything together beautifully.
🍳 Step 2: Mix the Wet Ingredients for Binding
In a separate bowl, whisk together the 0.25 cup granulated sugar, 0.25 cup light corn syrup, and 0.25 cup heavy whipping cream until smooth. I like to mix this while the marshmallow mixture cools—it keeps the process moving efficiently. The sugar and corn syrup will help create that perfect chewy texture we all love.
Slowly pour the warm marshmallow mixture into the wet ingredients while stirring constantly. Add the 1 cup graham cracker crumbs and mix until everything is fully combined and the mixture holds together when pressed. If it's too sticky, add a few more graham cracker crumbs—this ensures the pinwheels will hold their shape when rolled.
🥘 Step 3: Prepare the Chocolate Swirl Layer
In a microwave-safe bowl, melt the 1 cup semi-sweet chocolate chips in 30-second intervals, stirring between each interval until completely smooth. Stir in the 1 tbsp unsweetened cocoa powder until fully incorporated. Let this cool slightly for 2 minutes—it should be thick enough to hold its shape when drizzled but still pourable.
Line a baking sheet with the 1 sheet parchment paper and spread the marshmallow-graham cracker mixture evenly into a ¼-inch thick layer, about 12x15 inches. Use an offset spatula to create an even surface. Now's the fun part—drizzle the melted chocolate in zigzag lines across the top, leaving about ½-inch between each line.
🔪 Step 4: Roll and Cut the Pinwheels
Working quickly, sprinkle the 3 cups lightly crushed rice krispies cereal evenly over the chocolate-drizzled layer. Press gently but firmly to adhere the cereal to the top. This is where you'll see those beautiful golden rice krispies peeking through the chocolate.
Lift one corner of the parchment paper and carefully roll the entire mixture into a 12-inch log, pressing gently as you go to compact it. Trim the ends if needed for a clean look. Using a serrated knife, cut the log into 1-inch thick slices—this gives you about 12-14 pinwheels depending on how thick you cut them.
🍽️ Step 5: Finish and Serve with Flaky Salt
Place the pinwheels on a fresh sheet of parchment paper and let them cool completely for 15 minutes. This resting time allows them to set properly and makes them easier to handle. While they cool, melt any remaining chocolate from the bowl and drizzle a tiny amount over each pinwheel for extra decadence.
Just before serving, sprinkle each pinwheel with a pinch of 0.5 tsp flaky sea salt. The salt enhances all those sweet flavors and gives you that perfect s'mores balance. Serve warm for the ultimate gooey experience—these pinwheels are best enjoyed fresh from the oven (or in this case, fresh from the fridge after cooling).
Pro Tips For Making Rice Krispie S'Mores Pinwheels
- Melt Butter Slowly: I learned this the hard way—dumping all that butter in at once turns your marshmallows into a greasy mess. Heat the butter over low heat until it’s just melted, then stir in the marshmallows gradually so they melt evenly without scorching.
- Toast Marshmallows First: Skip the microwave—toss those mini marshmallows in a dry skillet over medium-low for 30 seconds until they’re just puffed. They’ll melt smoother and add a toasty depth the microwave can’t match.
- Press Pinwheels Firmly: Loose layers mean crumbly, sad pinwheels. Pack the graham crumb mixture tightly into your tortilla, then roll with enough pressure to hold its shape—like you’re trying to squeeze toothpaste out of a tube.
- Chill Before Slicing: Cutting warm pinwheels = messy, crumbly chaos. Pop them in the fridge for 10 minutes first—they’ll slice cleanly and hold together when you serve them. (Yes, even if you’re impatient like me.)
Flavor customization for these flavors
Spicy S'mores Twist
Add a kick to your pinwheels by mixing ½ tsp cayenne pepper into the melted chocolate before drizzling. For a milder heat, swap in ½ tsp cinnamon or ¼ tsp smoked paprika—both add warmth without overpowering.
I love pairing this with a sprinkle of chili powder on top for a festive touch. 🌶️
Peanut Butter S'mores
Stir ½ cup creamy peanut butter into the marshmallow mixture for a nutty depth. Use Skippy Natural for the best flavor, and add 1 tbsp honey to balance the richness. This combo reminds me of s'mores with a PB&J twist—perfect for peanut butter lovers. 🥜
Cookie Dough Swirl
Replace the graham cracker crumbs with 1 cup crushed chocolate chip cookies (like Oreos or homemade chocolate chip cookies) and fold in ¼ cup mini chocolate chips for hidden cookie dough pockets. This adds a chewy, cookie-like texture that pairs perfectly with the marshmallow gooeyness. 🍪
White Chocolate Raspberry
Swap the semi-sweet chocolate for 1 cup white chocolate chips and fold in ¼ cup raspberry jam into the marshmallow mixture. The tart raspberry brightens the sweetness, and the white chocolate adds a creamy contrast. Drizzle with extra melted white chocolate before serving for a luxurious finish. 🍓
Salted Caramel Drizzle
After rolling and cutting the pinwheels, drizzle each one with 1 tbsp salted caramel sauce (like Trader Joe's) and sprinkle with flaky sea salt. The caramel adds a buttery richness that complements the marshmallow perfectly. This is my go-to upgrade for a restaurant-quality touch. 🍯
Coffee Infusion
Add 1 tsp instant coffee granules to the melted chocolate for a mocha-inspired twist. The coffee enhances the chocolate flavor without making it bitter. This works especially well with dark chocolate or white chocolate for a sophisticated dessert. ☕

Frequently asked questions
Why do my pinwheels crumble when cutting?
The most common reason is that the mixture wasn't chilled long enough before cutting. Let the rolled log sit in the fridge for at least 30 minutes before slicing—this helps the chocolate set properly and gives the rice krispies time to crisp up. Also, make sure your graham cracker crumbs aren't too fine (they should hold the shape). If they still crumble, add 1 extra cup of crushed rice krispies to the mixture for better binding.
Can I make these pinwheels ahead of time?
These actually taste better the next day as the marshmallow softens slightly. Store them in an airtight container with parchment paper between layers for up to 5 days at room temperature. For longer storage, freeze them for up to 2 months. Just let them sit at room temperature for 10-15 minutes before serving to bring back that gooey texture.
What's the best way to reheat these pinwheels?
For maximum gooeyness, warm them in the microwave for 10-15 seconds or place them in a 300°F oven for 3-5 minutes. If you prefer extra crispy rice krispies, toast them in the oven. The marshmallow will soften beautifully, and the chocolate will melt just enough to create that perfect s'mores experience.
Can I substitute graham crackers with something else?
Yes! For a gluten-free option, use 1 cup crushed gluten-free graham crackers or 1 cup almond flour mixed with 1 tbsp melted butter. For extra crunch, try crushed pretzels (about 1 cup)—they add a salty contrast that works surprisingly well with the sweet filling. Just adjust the amount slightly if your substitute is more/less crumbly than graham crackers.
How do I prevent the chocolate from seizing when melting?
Chocolate seizes when it gets too hot or comes into contact with water. Always melt it in short 30-second bursts in the microwave, stirring between each interval. For a foolproof method, use a double boiler—place a heatproof bowl over a pot of simmering water (not touching) and melt the chocolate gently. If it does seize, try adding 1 tsp vegetable oil or butter and stirring vigorously to bring it back together.
