Ingredients for rice krispie s'mores pinwheels
These nostalgic treats blend crispy Rice Krispies with gooey chocolate and marshmallow magic for a showstopper dessert.
| Ingredient | Amount | Notes |
|---|---|---|
| Rice Krispies Cereal 🍪 | 6 cups | Original flavor preferred |
| Unsalted Butter 🧈 | ½ cup | Melted, full-fat for richness |
| Semi-Sweet Chocolate Chips 🍫 | 1 ½ cups | High-quality for best melt |
| Mini Marshmallows 🧸 | 2 cups | Standard size, not jumbo |
| Graham Cracker Crumbs 🍪 | 1 cup | Finely crushed, no lumps |
| Vanilla Extract 🌿 | 1 tsp | Pure extract for flavor |
| White Chocolate Chips 🍫 | ½ cup | For optional drizzle |
| Marshmallow Fluff 🧸 | ½ cup | For extra gooeyness |
| Granulated Sugar 🍚 | 1 tbsp | For extra sweetness |
| Large Egg 🥚 | 1 whole | For binding (optional) |
| Powdered Sugar 🍚 | 2 tbsp | For dusting, optional |
The Rice Krispies are the star here—original flavor is non-negotiable for that classic crunch. Grab the big family-sized box from Target or Walmart—they’re cheaper per ounce and last forever. For the chocolate, Ghirardelli or Nestlé chips melt perfectly, but don’t skimp on quality. Mini marshmallows are a must (the jumbo ones won’t blend right), and Kraft or Jet-Puffed are the gold standard. Graham crackers? Honey Maid is my go-to—they’re sweet enough to balance the chocolate without overpowering. If you’re feeling fancy, toast the crumbs lightly in the oven for a deeper flavor (worth the extra minute!).
No vanilla extract? Vanilla bean paste works too, or skip it entirely—the marshmallows and chocolate carry enough sweetness. Short on marshmallows? Crushed marshmallow fluff at half the amount gives the same gooey texture. The egg is optional but helps bind everything together—leave it out if you’re making a vegan version (just add an extra tbsp of melted butter). For the white chocolate drizzle, Ghirardelli or Enjoy Life brands melt smoothly. No white chocolate? A mix of milk chocolate and powdered sugar works in a pinch, though it won’t be as pretty. And if you’re feeling extra, swap half the semi-sweet chips for dark chocolate for a sophisticated twist.
These pinwheels are best fresh but keep for 3 days in an airtight container at room temp (if they last that long!). For longer storage, freeze the unbaked log for up to 2 months—just slice and bake straight from frozen. The optional powdered sugar dusting adds a pretty finish and keeps them from sticking. Serve warm for that classic s’more experience, or chill slightly for cleaner bites. Pro tip: Double the recipe and freeze half—perfect for last-minute parties or nostalgic cravings!

Step-by-step instructions for Rice Krispie s'mores pinwheels
Here's how to make these decadent pinwheels with gooey, melty layers and crispy edges.
Melt Butter and Chocolate for the Base
In a large microwave-safe bowl, combine the 0.5 cup unsalted butter and 1.5 cups semi-sweet chocolate chips. Microwave in 30-second bursts, stirring between each interval, until the mixture is completely smooth and reaches 110°F. This gentle melting prevents burning while ensuring the chocolate fully incorporates with the butter.
Here's the thing—don't rush this step. You're looking for a glossy, ribbon-like consistency where the chocolate flows effortlessly. If it looks streaky, add another 10-second burst and stir vigorously. This base will bind everything together, so getting it right is crucial for that perfect pull-apart texture.
Mix in Marshmallows and Graham Cracker Crumbs
Remove the melted chocolate mixture from the microwave and immediately stir in the 2 cups mini marshmallows and 1 cup graham cracker crumbs. Work quickly—marshmallows start setting as soon as they hit the warm chocolate. Fold everything together until the marshmallows are completely melted and the graham cracker crumbs are evenly distributed.
I like to use a silicone spatula for this step because it's flexible enough to scrape up every last bit from the bowl's edges. You should have a thick, dough-like mixture that holds its shape when pressed. If it's too sticky, add 1 tablespoon granulated sugar to help bind it together. This is where that optional egg comes in handy—if your mixture is too loose, crack in the 1 whole large egg and mix until just combined.
Fold in Rice Krispies and Vanilla
Gently fold in the 6 cups rice krispies cereal using your hands or a spatula. The key here is to mix just enough to distribute the cereal evenly without crushing it. You want each bite to have that satisfying crunch—so don't overmix. Once incorporated, stir in the 1 teaspoon vanilla extract for that classic s'mores flavor.
At this point, your mixture should look like a thick, crumbly dough with visible rice krispies throughout. If it's still too sticky, chill it in the refrigerator for 10-15 minutes while you prepare the next components. This makes it much easier to handle and roll into pinwheels without falling apart.
Roll and Chill the Pinwheels
Line a baking sheet with parchment paper and spread the mixture into a ¼-inch thick rectangle (about 12x8 inches). Press down gently but firmly to create an even layer. Then, using a sharp knife or pizza cutter, cut the rectangle into 12 even strips (about 2x4 inches each).
Roll each strip tightly into a pinwheel shape, starting from the long end. Place them seam-side down on the prepared baking sheet and chill in the refrigerator for at least 1 hour or until firm. This chilling step is non-negotiable—it allows the pinwheels to hold their shape when you serve them. If you're impatient, you can freeze them for 30 minutes to speed up the process.
Melt and Drizzle the Toppings
While the pinwheels chill, melt the 0.5 cup white chocolate chips and 0.5 cup marshmallow fluff together in the microwave in 20-second intervals, stirring between each burst until smooth. The marshmallow fluff will give your pinwheels that extra gooey texture that makes them irresistible.
Once the pinwheels are firm, transfer them to a serving platter. Drizzle the melted white chocolate mixture over the top, letting it cascade down the sides for that beautiful, decadent look. For extra flair, sprinkle with 2 tablespoons powdered sugar while the chocolate is still wet. Serve immediately while the drizzle is still glossy and the pinwheels are at their perfect texture—crispy on the outside, gooey on the inside.
Pro Tips For Making Rice Krispie S'Mores Pinwheels
- Melt Marshmallows Slowly: I learned this the hard way—dumping all the mini marshmallows in at once turns them into a sticky, rubbery mess. Instead, add them in batches of 5-6 at a time, stirring constantly until they’re just melted but not browned. If you see the butter starting to bubble too hard, pull the pan off the heat for 10 seconds to let the marshmallows catch up.
- Toast Cereal Lightly First: Skip the pre-toasting step, and your pinwheels will taste like a sad, soggy cereal bar. Pulse the Rice Krispies in a food processor for 10-15 seconds—just until they’re slightly broken up, not powdered—then lightly toast them in a dry pan over medium heat for 2-3 minutes. This adds a subtle crunch that makes all the difference.
- Mix Graham Crumbs Last: Adding the graham cracker crumbs too early turns the mixture into a dense, clumpy brick. Wait until the butter, chocolate, and marshmallow blend is fully smooth and just starting to thicken, then fold in the crumbs with a spatula. Press the dough gently—it should hold shape but still be pliable, not crumbly.
- Chill Dough Before Rolling: Roll out that dough while it’s still warm, and it’ll stick to everything like glue. Pop the whole batch in the fridge for 15-20 minutes, then dust your rolling surface with extra graham crumbs to prevent sticking. This also makes slicing cleaner pinwheels way easier—no more jagged edges or dough tears.
Flavor customization for rice krispie s'mores pinwheels
Spicy S'mores Twist
Add a kick to your classic pinwheels by mixing ¼ teaspoon cayenne pepper or ½ teaspoon chili powder into the melted chocolate base. For a sweeter heat balance, fold in 2 tablespoons of honey or hot honey with the marshmallows.
This works surprisingly well with the chocolatey richness—just don't overdo it, or the crunchy Rice Krispies will lose their star quality. 🌶️
Peanut Butter S'mores Fusion
Swap out half the semi-sweet chocolate chips for ½ cup creamy peanut butter (like Jif or Skippy) in the melted base. Add 1 teaspoon peanut butter powder to the graham cracker crumbs for extra depth.
This Southern-inspired twist brings nutty warmth that pairs perfectly with the marshmallow gooeyness. Serve with a side of warm milk for dipping!
Cookie Dough Swirl
Replace half the marshmallows with ½ cup cookie dough bits (use Nilla Wafer or chocolate chip for best results). Fold in 1 tablespoon mini chocolate chips for extra texture.
The cookie dough adds a chewy contrast that makes each bite even more indulgent. For a vegan option, use Enjoy Life cookie dough and dairy-free chocolate chips.
Salted Caramel Layer
Create a decadent layer by drizzling ¼ cup salted caramel sauce (like Smucker's) over the rolled pinwheels before baking. Brush it on with a pastry brush, then sprinkle with flaky sea salt while still warm.
The caramel adds a buttery-sweet contrast that elevates the classic s'mores flavors to restaurant-quality dessert status.
Fruity S'mores Surprise
Add a fresh twist by folding in ½ cup finely chopped dried cranberries or apricots with the graham cracker crumbs. For a brighter flavor, mix in 1 teaspoon orange zest with the vanilla extract.
The tartness cuts through the sweetness beautifully, making these pinwheels perfect for fall gatherings or as a sophisticated dessert option.
Nutty Crunch Boost
For extra texture, fold in ½ cup chopped pecans or walnuts with the Rice Krispies. Toast the nuts in a dry pan for 3-4 minutes until fragrant, then let them cool before mixing.
The nutty crunch adds a sophisticated contrast to the creamy filling. If you're feeling adventurous, try toasted coconut flakes instead for a tropical-inspired variation.

Frequently asked questions
Can I make these pinwheels ahead of time?
Roll and chill the unbaked pinwheels, then wrap them tightly in plastic wrap. Store in the fridge for up to 3 days or freeze for 2 months. Bake straight from frozen—just add 2-3 extra minutes to the baking time. The flavors actually improve overnight as the ingredients meld together!
Why is my mixture too sticky to roll?
This usually happens if the chocolate butter base wasn't fully cooled before adding Rice Krispies, or if you skipped the chilling step. Fix it by refrigerating the dough for 15-20 minutes to firm up, or add 1 extra tablespoon of graham cracker crumbs to absorb moisture. If it's still too wet, fold in 1 more egg white to help bind everything.
What's the best way to slice them evenly?
Use a sharp, hot knife (dip in hot water between slices) for clean cuts. Roll the chilled log tightly and slice into ½-inch thick pinwheels. For perfect circles, cut the log diagonally first to create a triangle, then slice into even wedges. A pizza cutter works great too—just press firmly for crisp edges.
Can I make these without marshmallow fluff?
Yes! Replace the fluff with 1 cup whipped marshmallow cream (like Fluff) or ½ cup melted marshmallows mixed with 1 tablespoon corn syrup to prevent graininess. For a lighter texture, fold in ¼ cup whipped cream with the graham cracker crumbs. The result will be slightly less gooey but still delicious.
How do I prevent the pinwheels from falling apart?
Chill the rolled pinwheels for at least 1 hour before baking—this is non-negotiable! For extra stability, lightly brush the rolled log with egg wash (1 egg white + 1 tsp water) before slicing. If they still crumble, your chocolate butter base may need more binding—add 1 extra tablespoon of melted butter to the mixture.
