How to Make Pumpkin Pie Rice Krispies Treats Recipe
Step 1: Prepare Your Pan
Start by spraying a 9-inch round pie dish or cake pan with cooking spray to ensure your Pumpkin Pie Rice Krispies Treats come out easily. This sets the stage perfectly for building your treat crust and filling.
Step 2: Make the Crust Mixture
In a large microwave-safe bowl, melt 4 ounces of marshmallows and 1 ½ tablespoons of butter by microwaving for 45 seconds, stirring, then another 30 seconds until silky smooth. Stir in ½ teaspoon vanilla extract for that aromatic lift. This mixture will hold your crust together wonderfully.
Step 3: Combine Crust Ingredients
Next, fold in 1 cup of Rice Krispies cereal and the graham cracker crumbs, mixing until everything is well coated. The graham crumbs add a subtle crunch and slightly nutty flavor reminiscent of a pumpkin pie crust, giving this treat its signature twist.
Step 4: Form the Crust in the Pan
Turn your crust mixture out into the prepared pan and, using lightly sprayed hands, press it evenly around the edge to create a firm 1-inch thick crust. This creates a solid base that will hold the filling nicely and look like a true pumpkin pie shell.
Step 5: Prepare the Pumpkin Pie Filling
For the filling, melt the remaining 6 ounces of marshmallows with 2 ½ tablespoons butter in another microwave-safe bowl. Start with 60 seconds on high, stir, then continue for 30 seconds until smooth. Stir in remaining ½ teaspoon vanilla, kosher salt, orange food coloring, and the fragrant pumpkin pie spice until the mixture glows with delicious color and smell.
Step 6: Add the Remaining Cereal
Fold in the remaining 3 cups of Rice Krispies cereal so that every bit is coated with that cozy, spiced marshmallow mix. This filling layer will be the star, giving you absolute pumpkin pie vibes in every bite.
Step 7: Assemble and Chill
Place the filling gently into the center of your pie crust in the pan and press down with sprayed hands to fill the middle smoothly. Let your Pumpkin Pie Rice Krispies Treats set at room temperature for at least 30 minutes to firm up before slicing into 8 delicious wedges. Whipped cream on top is optional but highly recommended for extra indulgence!
How to Serve Pumpkin Pie Rice Krispies Treats Recipe

Garnishes
To make these treats even more festive and irresistible, try decorating with a dollop of freshly whipped cream or a sprinkle of extra pumpkin pie spice on top. A dusting of powdered sugar can add a lovely, snowy look that enhances the cozy pumpkin theme perfectly.
Side Dishes
Serve these fun snacks alongside a warm cup of spiced apple cider or a creamy chai latte for a harmonious autumn-inspired spread. If you want a more substantial dessert setup, offer fresh fruit like sliced apples or pears to balance the sweetness.
Creative Ways to Present
Try packaging individual slices in small clear boxes or festive bags as a great party favor or gift idea. You can also arrange them on a tiered dessert stand decorated with mini pumpkins and fall leaves for a charming centerpiece that will impress all your guests.
Make Ahead and Storage
Storing Leftovers
Store any leftover Pumpkin Pie Rice Krispies Treats in an airtight container at room temperature for up to 3 days. Keeping them sealed well ensures they stay soft and chewy without drying out.
Freezing
If you want to keep them longer, wrap individual slices tightly in plastic wrap and place them in a freezer-safe bag or container. They’ll last up to 1 month frozen. Thaw them at room temperature when you’re ready to enjoy.
Reheating
Reheating isn’t usually necessary since these treats are best enjoyed at room temperature, but if you prefer them warmed slightly, microwave for 5-10 seconds. Just be careful not to overheat or the marshmallows may become too sticky.
FAQs
Can I use mini marshmallows instead of regular-sized ones?
Yes, mini marshmallows work just as well and will melt a bit faster, so keep an eye on them when microwaving to avoid burning.
What if I don’t have pumpkin pie spice? Can I make my own?
Absolutely! Mix ground cinnamon, nutmeg, ginger, and cloves together to create your own blend. Typically, 1 ½ teaspoons of this mix will give the same warm flavor.
Is it possible to make these treats gluten-free?
Yes, simply use gluten-free Rice Krispies cereal and substitute the graham cracker crumbs for gluten-free graham crumbs or crushed gluten-free cookies to keep everything safe and delicious.
Can I add nuts or chocolate chips to the recipe?
Definitely! Feel free to sprinkle in chopped pecans or mini chocolate chips into either the crust or filling for extra texture and flavor bites.
How long does it take for the treat to set before serving?
It’s best to let your Pumpkin Pie Rice Krispies Treats set for at least 30 minutes at room temperature so they firm up properly and hold their pie shape when sliced.
