Can I Use Fresh Pumpkin Instead of Canned?

Canned pumpkin puree is best for this recipe because of its consistency. Fresh pumpkin tends to have more moisture, which could make your bars too soft or sticky. If you want to use fresh pumpkin, be sure to cook and strain it thoroughly so it’s thick and smooth like canned puree.

How To Make the Pumpkin Pie Rice Krispie Treats

Step 1: Melt the Butter and Marshmallows

In a large pot over medium heat, melt 1/4 cup unsalted butter. Once melted, stir in 5 cups of mini marshmallows. Stir constantly until smooth and fully melted.

Step 2: Add Pumpkin and Flavorings

Lower the heat and stir in 1/3 cup pumpkin puree, 1 teaspoon pumpkin pie spice, 1/2 teaspoon vanilla extract, and a pinch of salt. Mix until combined and heated through, about 1-2 minutes.

Step 3: Mix in the Cereal

Remove the pot from heat and fold in 5 1/2 cups of Rice Krispies cereal. Stir until all the cereal is evenly coated with the marshmallow-pumpkin mixture.

Step 4: Press into Pan

Grease an 8×8-inch pan with nonstick spray or line with parchment. Press the mixture into the pan gently using a spatula or clean hands.

Step 5: Add White Chocolate (Optional)

Melt 1/2 cup white chocolate chips in the microwave in 20-second intervals until smooth. Drizzle or spread over the treats. Let them cool completely at room temp or in the fridge until set.

How to Store Pumpkin Pie Rice Krispie Treats

Store your treats in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the fridge for up to a week. If you’ve added the white chocolate topping, place parchment paper between layers to prevent sticking. Avoid freezing—the texture won’t hold up as well.

Frequently Asked Questions

Can I use jumbo marshmallows instead of mini?
Yes, just chop them up for easier melting. Use the same 5-cup measurement.

Can I double the recipe for a crowd?
Absolutely! Use a 9×13 pan and double all ingredients. The thickness will stay roughly the same.

Is this recipe gluten-free?
Check your cereal. Some brands of crisped rice contain malt flavoring (a gluten source). Look for certified gluten-free rice cereal.

Can I use brown butter for deeper flavor?
Yes, browning the butter adds a toasty, nutty note that complements pumpkin perfectly. Just keep an eye on it so it doesn’t burn.

How long do they take to set?
About 30 minutes at room temp or 15 minutes in the fridge. Once firm, they’re ready to slice.
