Ingredients You’ll Need

The beauty of Pumpkin Pie Rice Krispies Treats is in their simplicity—every ingredient truly counts. Each item works behind the scenes, from lending creamy richness and subtle spice, to bringing structure and festive color. Here’s what you’ll need and why:

Unsalted butter: Adds richness and helps everything meld together without being too salty.
Marshmallows: The glue that holds these treats together, providing sweetness and chew—I recommend fresh, fluffy ones for optimal meltiness.
Vanilla extract: A splash elevates both the flavor and aroma, making the treats taste homemade and special.
Rice Krispies cereal: This classic cereal brings essential crispy crunch and acts as the ultimate canvas for all the fall flavors.
Pumpkin pie spice: The signature blend that transforms these treats with warm, cozy notes of cinnamon, ginger, and nutmeg.
Orange food coloring: Totally optional, but it wins hearts by giving your “pie filling” that vibrant pumpkin pie look.
Whipped cream (optional): For the most adorable pie effect, dollop some on top just before serving.
Equipment: An 8-inch round cake pan, piping bag, and star-shaped piping tip will help you form and decorate your festive pie.

How to Make Pumpkin Pie Rice Krispies Treats

Step 1: Prepare Your Pan

Begin by generously coating your 8-inch round cake pan with nonstick spray. This will ensure a flawless release and those classic pie edges we’re after. Set it aside—you’ll be glad everything is prepped before the sticky fun begins.

Step 2: Make the Rice Krispies Crust

In a medium saucepan over medium-low heat, melt 1 1/2 tablespoons of unsalted butter. Toss in 2 cups of marshmallows and stir constantly until smooth and melty. Add half a teaspoon of vanilla, then fold in 3 cups of Rice Krispies cereal. Once each crispy is well coated, scoop the mixture into your prepared pan. Using a greased spatula (or your hands, lightly buttered!), press the mixture firmly around the inside edge to form a thick, even crust—about an inch wide. Let it cool while you whip up the spiced filling.

Step 3: Create the Pumpkin Spice Filling

Wipe out your pan if needed, and add 2 1/2 tablespoons of unsalted butter along with the pumpkin pie spice. Let the spice bloom in the butter over medium-low heat for a minute—this brings out the flavor beautifully! Add 3 cups of marshmallows, stirring constantly until the marshmallows melt into a fragrant, golden goo. Stir in 2 teaspoons of orange food coloring, then mix in 4 cups of Rice Krispies cereal until every piece glows autumn orange.

Step 4: Assemble the “Pie”

Work swiftly to press the pumpkin-spiced filling into the center of your Rice Krispies crust, packing it down firmly so your “pie” holds its structure. Let everything cool completely—this is the secret to neat slices and a perfect pie replica.

Step 5: Unmold and Decorate

Place a serving plate on top of the cake pan, then invert both together so your “pie” flips out in one glorious piece. Slice into wedges using a sharp, buttered knife. For that classic pumpkin pie look, pipe or dollop starbursts of whipped cream onto each slice just before serving. Your Pumpkin Pie Rice Krispies Treats are ready to dazzle!

How to Serve Pumpkin Pie Rice Krispies Treats

Garnishes

There’s nothing quite like a cloud of whipped cream atop each “pie” wedge—it’s both playful and pretty. If you want to up the ante, sprinkle with a dash of cinnamon or a little grated nutmeg. For a kid-friendly touch, add decorative fall sprinkles or tiny fondant leaves.

Side Dishes

These Pumpkin Pie Rice Krispies Treats shine on a dessert platter with other fall favorites: think warm apple cider, hot cocoa, or mini caramel apples. For an after-school snack, pair a slice with a glass of cold milk or gently spiced chai for pure autumn bliss.

Creative Ways to Present

For parties, try making mini “pies” using a muffin tin—adorable and perfectly portioned! Or serve the wedges in festive cupcake wrappers for a bake sale look. If you’re feeling bold, pipe whipped cream along the whole top and create swirls or faces for a fun, seasonal touch.

Make Ahead and Storage

Storing Leftovers

To keep your Pumpkin Pie Rice Krispies Treats fresh and chewy, store them in an airtight container at room temperature. They’ll stay perfect for up to 4–5 days, making them just as suitable for weekday snacks as for party prep.

Freezing

If you want to make your pumpkin pie treats far in advance, just wrap individual pieces tightly in plastic wrap and place them in a freezer-safe bag or container. They’ll hold up for about two months. For best flavor and texture, thaw at room temperature for a few hours before serving.

Reheating

Though Pumpkin Pie Rice Krispies Treats are meant to be enjoyed at room temperature, if they’ve become a little too firm, a quick 5–10 second burst in the microwave will restore their gooey charm. Be careful not to overheat them or the cereal can become tough.

FAQs

Do I have to use orange food coloring?

Not at all! The food coloring is purely for that “pumpkin pie” look. If you skip it, your treats will still taste delicious—a little less visually pumpkin-y, but just as fun. You can also try natural alternatives like a dab of carrot juice or turmeric.

Can I substitute pumpkin spice marshmallows?

Absolutely! If you spot seasonal pumpkin spice marshmallows at the store, use them instead of the regular ones and skip the pumpkin pie spice in the filling. It saves a step and amps up the cozy flavor.

What’s the best way to keep the treats from sticking?

Always grease your pan and utensils thoroughly. A little bit of butter or nonstick spray on your spatula (or even your hands) makes molding and pressing the mixture much easier.

Can I double the recipe?

Yes, you can easily double the whole recipe. Just use a larger pan—like a 9×13 baking dish—and adjust the thickness to your preference. Keep an eye on cooling time, as a thicker pie will need longer to set.

How do I cut clean pie wedges?

For pristine slices, wait until the treats are completely cool, and use a sharp knife dipped in hot water or lightly coated with butter. Wipe the blade between each cut for tidy, photogenic wedges.

Final Thoughts

If you love both pumpkin pie and crispy marshmallow treats, these Pumpkin Pie Rice Krispies Treats truly are the best of both worlds—a showstopper in flavor, festivity, and fun. Give them a try and watch them become the new highlight of your fall celebrations!
