Why You’ll Love This Pumpkin Spice Rice Krispie Treats Recipe

Pumpkin spice season is about more than just lattes, and this recipe proves it. You’ll love how easy it is to put together in under 20 minutes, with just a handful of pantry staples. The pumpkin puree adds a rich, autumnal depth, while the marshmallows keep everything fluffy and fun. It’s also a great no-bake option for busy days when the oven just isn’t an option.

Plus, it’s easy to adapt! Add white chocolate chips, drizzle with caramel, or toss in some toasted pecans to really make it your own. It’s fall flavor in the palm of your hand.

Can I Use Canned Pumpkin or Fresh Pumpkin Puree?

Both work, but canned pumpkin puree is the easiest and most consistent option for this treat. Make sure you use plain pumpkin puree, not pumpkin pie filling, which already has sugar and spices added. If using homemade puree, try to cook it down a bit so it’s thicker and not too watery, otherwise it can change the texture of the final bars.

Ingredients for the Pumpkin Spice Rice Krispie Treats

Pumpkin Spice Rice Krispie Treats only need a few key ingredients, but each one plays an important role in bringing out that rich, autumnal flavor we all crave when the leaves start turning.

Unsalted Butter – This gives the bars richness and helps melt the marshmallows evenly.

Pumpkin Puree – Brings that authentic fall flavor and a subtle earthiness. Be sure it’s pure pumpkin, not pie filling.

Mini Marshmallows – They create the sticky, gooey base that holds everything together and makes the bars deliciously chewy.

Pumpkin Pie Spice – A warm blend of cinnamon, nutmeg, ginger, and cloves that defines the flavor of this dessert.

Vanilla Extract – Rounds out the spice with a smooth sweetness.

Rice Krispies Cereal – The crunch factor. It’s what gives these treats their iconic texture.

Salt – Just a pinch enhances the flavor of the spices and balances the sweetness.

How To Make the Pumpkin Spice Rice Krispie Treats

Step 1: Melt the Butter and Pumpkin

In a large saucepan over medium heat, melt the butter. Stir in the pumpkin puree and let it cook for 2-3 minutes to reduce excess moisture. This helps keep your treats from getting soggy.

Step 2: Add Marshmallows and Spice

Add the mini marshmallows to the pot and stir until melted and smooth. Stir in the pumpkin pie spice, vanilla extract, and a pinch of salt until everything is combined.

Step 3: Mix in the Cereal

Remove from heat and quickly fold in the Rice Krispies cereal. Stir until all the cereal is evenly coated with the pumpkin marshmallow mixture.

Step 4: Press into Pan

Transfer the mixture into a greased 9×13-inch pan. Use a buttered spatula or parchment paper to gently press it down evenly.

Step 5: Cool and Cut

Let the treats cool completely before cutting into squares. If you can wait that long, of course!
