- Rice Krispies cereal (6 cups): The foundation that adds irresistible crunch and lightness.
- Unsalted butter (1/4 cup): Provides smooth richness and helps melt everything together.
- Mini marshmallows (10 oz bag): Essential for that classic sticky, chewy texture.
- Vanilla extract (1/2 teaspoon): Enhances sweetness and rounds out the flavors.
- Pumpkin pie spice (1 teaspoon): Brings the warm, signature autumnal notes that make this recipe special.
- Ground cinnamon (1/4 teaspoon, optional): Adds extra spice depth for pumpkin spice enthusiasts.

- White chocolate drizzle or candy corn (optional): For festive decoration and extra sweetness.
How to Make Pumpkin Spice Rice Krispie Treats Recipe
Step 1: Prepare the Pan
Start by greasing a 9×13-inch baking dish with butter or a non-stick spray. This simple step ensures your treats will come out cleanly without sticking, making cutting and serving an easy task later on.
Step 2: Melt the Butter and Marshmallows
In a large pot over medium-low heat, melt the butter slowly. Once fully melted, add the mini marshmallows and stir consistently until the mixture is completely smooth and free of lumps. This mixture is the core that will bind your treats together, so patience here means perfect results.
Step 3: Add Pumpkin and Spices
Next, stir in the pumpkin puree, vanilla extract, pumpkin pie spice, and optional cinnamon. Keep mixing until everything is thoroughly combined, then let it cook for another minute so some of the moisture from the pumpkin evaporates. This step is key to keeping your treats from becoming too soggy while locking in that fabulous pumpkin flavor.
Step 4: Mix in the Cereal
Remove the pot from heat and gently fold in the Rice Krispies cereal. The goal here is to coat every crunchy piece with that rich marshmallow and pumpkin mixture without smashing the cereal into crumbs. A light hand guarantees those satisfying crispy textures we all love.
Step 5: Press into the Pan
Using a buttered spatula or hands greased with butter or non-stick spray, spread the mixture evenly into the prepared baking dish. Be sure not to press down too hard — you want the treats to stay fluffy and chewy rather than dense and hard. This is the stage that shapes your final bars, so a gentle, even press works best.
Step 6: Cool and Cut
Allow your Pumpkin Spice Rice Krispie Treats to cool completely for about 30 minutes. Cooling lets them set properly, making it easier to cut into neat squares without crumbling. Patience here leads to that perfect bite every time.
Step 7: Optional Decorations
If you want to take things up a notch, drizzle melted white chocolate over the top or sprinkle candy corn across the surface. These finishing touches add festive flair and an extra pop of sweetness that make your Pumpkin Spice Rice Krispie Treats Recipe truly stand out at any celebration.
How to Serve Pumpkin Spice Rice Krispie Treats Recipe

Garnishes
Simple garnishes like a sprinkle of cinnamon sugar, a drizzle of white chocolate, or a few candy corn pieces add playful seasonal charm. Not only do garnishes boost visual appeal, but they also give an extra hint of flavor that complements the pumpkin spice perfectly.
Side Dishes
These treats pair wonderfully with warm fall beverages like spiced cider, creamy pumpkin spice lattes, or even a simple hot chocolate. When served alongside a fresh fruit platter featuring apples and pear slices, they make for a balanced and inviting autumn dessert spread.
Creative Ways to Present
Try cutting your bars into bite-sized squares or fun fall-themed shapes using cookie cutters. You can stack them on a tiered tray with other seasonal treats or wrap individual pieces in parchment paper tied with rustic twine for a charming gift or party favor. Presentation is a delightful way to showcase the love and care behind your Pumpkin Spice Rice Krispie Treats Recipe.
Make Ahead and Storage
Storing Leftovers
After making your treats, store any leftovers in an airtight container at room temperature. They will stay fresh and chewy for up to 3 days, making them a perfect make-ahead snack or dessert for the week.
Freezing
You can freeze the treats by wrapping them tightly in plastic wrap and placing them in a freezer-safe container or bag. Frozen treats maintain their flavor and texture well for up to 2 months—just thaw at room temperature before enjoying.
Reheating
While these treats are usually eaten cold or at room temperature, if you prefer a warm, melty experience, a quick 10-15 second zap in the microwave softens them up beautifully without losing that signature chewiness. Just be careful not to overheat and melt the marshmallows completely.
FAQs
Can I use regular marshmallows instead of mini?
Yes, you can use regular marshmallows, but mini marshmallows melt more evenly and quickly, which helps achieve a smoother mixture. If using large marshmallows, give them a bit more time and stir gently until fully melted.
Is canned pumpkin purée the same as pumpkin pie filling?
No, pumpkin pie filling usually contains added spices and sugar, whereas canned pumpkin purée is plain cooked pumpkin. For this recipe, stick to pumpkin purée to control the flavor and avoid making your treats too sweet or overly spiced.
Can I make these treats vegan?
To make vegan Pumpkin Spice Rice Krispie Treats, substitute the butter with a plant-based alternative and use vegan marshmallows, which are often gelatin-free. Make sure the Rice Krispies cereal you choose is also vegan-friendly.
Can I add nuts or chocolate chips?
Absolutely! Adding chopped pecans, walnuts, or mini chocolate chips can add a delightful crunch or gooey bite. Just fold them into the cereal before pressing the mixture into the pan for best distribution.
What’s the best way to cut these treats without them crumbling?
Using a sharp knife lightly greased with butter or cooking spray helps the knife glide through the treats smoothly. Cut once the treats are fully cooled, and wipe the knife clean between cuts for polished squares.
Final Thoughts
This Pumpkin Spice Rice Krispie Treats Recipe is truly a seasonal treasure that’s easy enough for any home cook to tackle but impressive enough to steal the show at gatherings. The warm spices combined with that nostalgic crispy, chewy texture make these treats a perfect way to invite autumn into your kitchen. I can’t wait for you to try them and make this recipe a new favorite in your fall baking lineup!
