This Rice Krispie pumpkin pie recipe combines two autumn favorites into a dessert that’s creamy, spiced, and packed with nostalgic crunch. 🍂 The secret lies in blending pumpkin’s velvety richness with the iconic snap of Rice Krispies—creating a texture that’s both indulgent and satisfying.

Ingredients for rice krispie pumpkin pie
Eight ingredients transform into a pie that’s creamy, crunchy, and packed with autumn flavors—no crust needed.
| Ingredient | Amount | Notes |
|---|---|---|
| Canned Pumpkin Puree 🎃 | 1 cup | Unsweetened, 100% pumpkin |
| Large Eggs 🥚 | 4 whole | Room temperature for blending |
| Granulated Sugar 🍚 | 1 ½ cups | Light brown sugar for depth |
| Light Corn Syrup 🍯 | ½ cup | Karo brand preferred |
| Unsalted Butter 🧈 | ¾ cup | Melted, full-fat preferred |
| Vanilla Extract 🌿 | 2 tsp | Pure Madagascar bourbon |
| Pumpkin Pie Spice 🌶️ | 2 tsp | Or DIY blend (see tips) |
| Salt 🧂 | ½ tsp | Diamond Crystal kosher |
| Mini Marshmallows 🍫 | 1 ½ cups | Unmelted, jumbo size |
| Original Rice Krispies 🍞 | 1 ½ cups | Crushed into clusters |
| Heavy Whipping Cream 🥛 | 1 cup | Whipped to soft peaks |
| Powdered Sugar 🍚 | ¼ cup | For dusting whipped cream |
| Vanilla Ice Cream 🍦 | 2 cups | For serving (optional) |
The pumpkin puree is your foundation—Libby’s or Storehouse are the gold standards, but any unsweetened canned pumpkin works. For the marshmallows, mini jumbo from Trader Joe’s give the best texture, though regular mini marshmallows are fine in a pinch. The Rice Krispies? Original flavor only—no honey or other varieties. Pro tip: crush them into clusters before adding to the filling so they stay intact. The butter matters too—full-fat, unsalted gives that rich, velvety texture. If you’re feeling fancy, toast the crushed Rice Krispies lightly in a dry pan before mixing them in for extra crunch.
No pumpkin pie spice? DIY it with 2 tsp cinnamon, 1 tsp each ginger and nutmeg, and 0.5 tsp cloves. Out of marshmallows? Melted white chocolate chips work in a crunchy pinch, though they’ll change the texture slightly. For a lighter version, swap half the sugar for monk fruit sweetener—it’s intense, so start with half the amount. The whipped cream should be soft peaks only—overwhipping makes it grainy. And if you’re serving this warm, skip the whipped cream until the last minute so it stays fluffy.
This pie is best served warm, straight from the oven—the marshmallows get gooey and the Rice Krispies stay perfectly crisp. Store leftovers in the fridge for up to 5 days, but reheat gently (microwave in 30-second bursts) to avoid sogginess. For make-ahead prep, assemble the filling and refrigerate overnight—the flavors meld beautifully. Freezes for up to 3 months if you wrap it tightly in plastic. Serve with a scoop of vanilla ice cream for the ultimate fall treat—the contrast of warm pie and cold ice cream is next-level.

- Spiced Sweetness Without Fuss: That buttery pumpkin filling—sweetened just enough with sugar and corn syrup—tastes like fall in a bowl. The Rice Krispies add a satisfying crunch that balances the creamy center, and the eggs bind it all together so smoothly. It’s not overly complicated, but it hits all the right notes.

The portions are easy to adjust—make one small pie for a quick treat or double it for a crowd. It’s the kind of dessert that works for any gathering, no stress.
- Leftovers That Don’t Suck: Unlike most pies, this one actually tastes better the next day—if there’s any left, which there usually isn’t.

Step-by-step instructions for Rice Krispie pumpkin pie
Here's how to create the perfect fusion of creamy pumpkin and crispy Rice Krispie magic.
👨🍳 Step 1: Prepare the Pumpkin Filling
In a large mixing bowl, whisk together the 1 cup canned pumpkin puree, 1.5 cups granulated sugar, 0.5 cup light corn syrup, 2 tsp vanilla extract, 2 tsp pumpkin pie spice, and 0.5 tsp salt until completely smooth. The mixture should be thick but pourable—this ensures a perfectly set filling without being too dense.
In a separate saucepan, melt the 0.75 cup unsalted butter over low heat until completely liquid but not browned. Let it cool slightly before whisking it into the pumpkin mixture. This step is crucial—hot butter can cook the eggs prematurely when added later. The filling should now have a rich, velvety consistency with a beautiful autumnal hue.
🍳 Step 2: Add Eggs and Create the Base
Add the 4 whole large eggs to the pumpkin mixture one at a time, whisking vigorously after each addition until fully incorporated. The batter should thicken slightly but remain smooth. Here's the thing—I like to strain the mixture through a fine-mesh sieve at this point to ensure a silky texture without any lumps that could affect the pie's smoothness.
Pour the pumpkin mixture into an ungreased 9-inch pie dish and spread it evenly. The filling should come about ¾ of the way up the sides—this allows room for the Rice Krispie layer to sit comfortably without overflowing. Place the pie dish on a baking sheet to catch any potential drips during baking.
🔥 Step 3: Bake the Pumpkin Base
Preheat your oven to 350°F. Bake the pumpkin filling for 40-45 minutes until the center is just set but still slightly jiggly—this ensures it doesn't overcook while the top layer bakes. You'll know it's ready when the edges are set and the center still has a slight wobble (about 165°F internal temperature). Don't overbake—this pie needs to stay creamy!
While the pie bakes, crush the 1.5 cups original Rice Krispies into clusters by placing them in a plastic bag and gently crushing with a rolling pin. Set these aside—they'll add that signature crunch we're after.
🥘 Step 4: Assemble the Crunchy Top Layer
Remove the pumpkin pie from the oven and let it cool completely on a wire rack for at least 1 hour. This cooling step is non-negotiable—it allows the filling to set properly before adding the marshmallow layer. While it cools, prepare the topping by melting the 1.5 cups mini marshmallows in a microwave-safe bowl in 30-second intervals, stirring between each interval until completely smooth.
Spread the melted marshmallows evenly over the cooled pumpkin filling, creating a smooth layer. Immediately sprinkle the crushed Rice Krispie clusters evenly over the marshmallow layer. Press down gently with a spatula to help them adhere—this creates that perfect crunchy texture we're after. Let the pie sit at room temperature for 30 minutes to allow the marshmallow to set slightly.
⏰ Step 5: Whip the Cream and Serve
In a chilled mixing bowl, whip the 1 cup heavy whipping cream with the 0.25 cup powdered sugar until soft peaks form. This light, airy topping balances the rich pumpkin filling perfectly. Spread the whipped cream evenly over the Rice Krispie layer, creating a beautiful contrast of colors and textures.
Serve immediately with 2 cups vanilla ice cream on the side for scooping, or let it chill in the refrigerator for 1 hour before serving to enhance the flavors. Each bite should deliver that perfect combination of creamy pumpkin, gooey marshmallow, and crispy Rice Krispie clusters—trust me, it's worth every step!
Pro Tips For Making Rice Krispie Pumpkin Pie
- Melt Butter Slowly: Mix the butter into the pumpkin filling over low heat—just until it melts completely. I used to dump it in hot and wondered why the texture turned grainy later. This keeps the custard silky smooth without scrambling the eggs.
- Whisk Eggs Cold: Add the eggs to the warm pumpkin mixture one at a time, whisking vigorously after each. Cold eggs mixed into hot liquid curdle faster than you can say "soggy crust." A splash of cold milk (or even ice water) in the bowl helps too.
- Toast Cereal Lightly: Spread the Rice Krispies on a baking sheet and toast them at 300°F for 5–7 minutes, stirring once. This crisps them just enough to hold up in the pie without turning them into dust. (Yes, I’ve learned the hard way that skipping this step = a mushy top layer.)
- Chill Before Baking: Let the assembled pie sit uncovered in the fridge for at least 30 minutes before baking. This prevents the custard from leaking out the sides—especially if your oven runs hot. (I know, waiting feels like torture, but it’s worth it.)
Flavor customization for rice krispie pumpkin pie
Spiced Variations
Swap the pumpkin pie spice for chai-inspired warmth by adding ½ tsp cardamom and ¼ tsp black pepper to the filling.
For a Mexican twist, replace the pie spice with 1 tsp cinnamon, ½ tsp cumin, and a pinch of cayenne—this adds a subtle smoky depth that pairs beautifully with the marshmallow crunch. 🌶️
Sweet Additions
Boost the sweetness by folding in ½ cup chopped pecans or walnuts into the marshmallow layer before topping with Rice Krispies. For a caramelized touch, drizzle ¼ cup salted caramel sauce over the cooled pie before adding whipped cream.
I also love adding mini chocolate chips to the marshmallow mixture for a surprise chocolatey bite in every forkful.
Crunchy Alternatives
Replace the Rice Krispies with crushed graham crackers for a graham cracker crust effect, or use toasted coconut flakes for a tropical vibe. For a nutty crunch, toast ½ cup chopped hazelnuts and sprinkle them over the marshmallow layer.
If you want extra texture, mix in ¼ cup mini pretzels—the salty contrast with the sweet filling is incredible.
Seasonal Twists
For a holiday-inspired version, fold in ¼ cup crushed candy canes into the marshmallow layer for a minty surprise. In summer, swap the pumpkin for mashed sweet potato (use 1 cup puree) and reduce the sugar to 1 cup—the marshmallow-Rice Krispie combo still shines.
For a coffee lover’s twist, add 1 tsp instant espresso powder to the filling for a subtle mocha note.
Dietary Swaps
Make this gluten-free by using certified gluten-free Rice Krispies and gluten-free graham cracker crumbs if substituting. For a lower-sugar option, reduce the granulated sugar to 1 cup and add ¼ cup monk fruit sweetener (adjust to taste).
The marshmallows can be swapped for sugar-free marshmallows, though the texture will be slightly firmer. 💛

Frequently asked questions
Can I make this pie without a pie dish?
For a crust-free version, bake the pumpkin filling in a 9-inch round cake pan or even a deep skillet. Line it with parchment paper for easy removal. The key is to use the same baking time (40-45 minutes at 350°F) and let it cool completely before adding the marshmallow-Rice Krispie layer. The texture will be identical—just the presentation changes!
Why do my Rice Krispies get soggy?
This happens when the marshmallow layer melts too much before the Rice Krispies set. To fix it, chill the pie in the fridge for 15 minutes after assembling the top layer before serving. For extra insurance, press the crushed Rice Krispies down firmly with a spatula—they'll stay crispier when compressed. Also, use mini marshmallows (not regular size) for better texture.
Can I make this ahead of time?
Yes! Assemble the pie completely (including the whipped cream) and refrigerate for up to 24 hours. The flavors actually improve overnight. For serving, let it sit at room temperature for 10 minutes to soften the whipped cream slightly. If freezing, wrap tightly and thaw in the fridge—never microwave as it can make the marshmallow layer rubbery.
What's the best way to reheat leftovers?
Microwave in 20-second bursts on medium power, stirring between each interval. For oven reheating, cover loosely with foil and warm at 300°F for 10-15 minutes—this keeps the marshmallow gooey without overcooking the Rice Krispies. Pro tip: Add a fresh dollop of whipped cream when serving to restore that perfect contrast.
Can I use store-bought Rice Krispie treats?
Technically yes, but homemade crushed Rice Krispies give better texture. If using store-bought, crush them into clusters and toast lightly in a dry pan for 2-3 minutes to crisp up. For a shortcut, layer the pie with both melted marshmallows and crushed Rice Krispie treats—just press firmly so they stick. The flavor will be similar, though slightly less crisp.
