These Pumpkin Rice Krispie Treats are a fun twist on the classic snack! They’re made with crispy rice cereal, gooey marshmallows, and a splash of pumpkin flavor.
Perfect for fall, these treats are sweet, crunchy, and so easy to make! I love sharing them with friends, and they’re always a hit at gatherings. Who can resist a pumpkin treat? 🎃
Key Ingredients & Substitutions
Rice Krispies: This classic cereal gives the treat a crisp texture. If you can’t find Rice Krispies, try using any puffed rice cereal or even puffed corn for a fun twist.
Marshmallows: Regular or miniature marshmallows work perfectly here. If you prefer a vegetarian option, look for marshmallows made without gelatin or use a plant-based alternative like vegan marshmallows.
Pumpkin Puree: Canned pumpkin is convenient, but if you have fresh pumpkin, you can cook and puree it. Just make sure it’s well-drained to avoid excess moisture in the treat.
Pumpkin Pie Spice: If you’re out of pumpkin pie spice, you can mix cinnamon, nutmeg, and ginger. A little mix will capture that cozy autumn flavor just as well!
How Do I Make Sure My Treats Stay Chewy?
To keep your Pumpkin Rice Krispie Treats chewy and not too hard, focus on proper mixing and cooling. Here are key steps:
- After melting the marshmallows with butter, be sure to mix in the pumpkin and spices quickly, so the mixture stays warm and liquid.
- Avoid over-mixing the Rice Krispies into the marshmallow mix. Just stir until coated for the best texture.
- When pressing the mixture into the pan, use a buttered spatula or wax paper to prevent sticking, and don’t pack it too tightly.
- Allow the treats to cool at room temperature—this helps them keep their shape without becoming hard.

How to Make Pumpkin Rice Krispie Treats
Ingredients You’ll Need:
- 6 cups Rice Krispies cereal
- 3 tablespoons unsalted butter
- 1 (10 oz) package marshmallows (about 40 regular sized) or 4 cups miniature marshmallows
- 1/2 cup canned pumpkin puree
- 1 teaspoon vanilla extract
- 1 teaspoon pumpkin pie spice
- Orange and green pumpkin-shaped candies or gummy pumpkins (for garnish)
Time Needed to Prepare:
This recipe will take you about 15 minutes to prepare and then about 30 minutes to cool. So, you’ll be enjoying these tasty treats in about 45 minutes total!
Step-by-Step Instructions:
1. Prepare the Baking Pan:
Start by greasing a 9×13 inch baking pan with butter or non-stick spray. This will prevent your treats from sticking to the pan, making it easier to cut them later. Set the greased pan aside.
2. Melt the Butter:
In a large pot, melt the unsalted butter over low heat. Keep an eye on it to make sure it doesn’t burn. Stir it gently until completely melted.
3. Add Marshmallows:
Add the marshmallows to the melted butter and stir constantly. Keep mixing until the marshmallows are completely melted and the mixture is smooth. This is where the magic happens!
4. Mix in Pumpkin and Spices:
Once the marshmallows are melted, remove the pot from the heat. Immediately stir in the ½ cup of canned pumpkin puree, 1 teaspoon of vanilla extract, and 1 teaspoon of pumpkin pie spice. Mix it well until everything is combined.
5. Combine with Rice Krispies:
Next, quickly add the 6 cups of Rice Krispies cereal to your pot. Gently stir with a spatula until all the cereal pieces are coated with the marshmallow mixture. Be careful not to crush the Rice Krispies!
6. Press into the Pan:
Transfer the mixture into your prepared baking pan. Using a buttered spatula or a piece of wax paper, press the mixture firmly and evenly into the pan. This will help shape the treats. Let it cool completely at room temperature.
7. Cut and Decorate:
Once the treats are cooled, cut them into squares or your desired shape. For a fun finishing touch, top each treat with a pumpkin-shaped candy or gummy pumpkin.
8. Serve and Enjoy:
Your Pumpkin Rice Krispie Treats are now ready to enjoy! They’re perfect for fall gatherings or just a tasty snack at home. Grab a treat and enjoy the delicious pumpkin flavor!
