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

These fall-inspired treats are more than just a seasonal spin—they’re super quick to make, don’t require an oven, and are always a crowd-pleaser. Whether you’re hosting a Halloween party, adding something sweet to your Thanksgiving dessert table, or just feeling festive, this no-bake recipe will become your go-to. The pumpkin spice flavor blends beautifully with the buttery marshmallow base, creating that nostalgic-meets-new flavor that feels like fall in every bite.

What Kind of Marshmallows Should I Use?

For the best gooey consistency, use mini marshmallows. They melt faster and more evenly compared to jumbo ones, and they blend smoothly with the butter and pumpkin puree. If all you have on hand are the large ones, chop them up first to make melting easier.

Ingredients for the Pumpkin Spice Rice Krispie Treats

To make these treats taste like autumn, we’re bringing in just the right mix of cozy ingredients. You probably have most of them in your pantry already, especially if you’re a fan of fall baking. Here’s what you’ll need:

Unsalted Butter: Creates a rich, silky base that holds everything together.

Mini Marshmallows: These melt into the butter and form the sticky, chewy texture we all love.

Pumpkin Puree: Adds real pumpkin flavor and moisture. Make sure you’re using 100% pumpkin, not pie filling.

Pumpkin Pie Spice: This is the magic ingredient that turns a regular treat into a fall favorite.

Vanilla Extract: Enhances all the other flavors and adds warmth.

Rice Krispies Cereal: The iconic crunch that makes this treat irresistibly crispy.

How To Make the Pumpkin Spice Rice Krispie Treats

Step 1: Melt the Butter

Start by melting the butter in a large pot over medium heat. Stir it around as it melts to keep it from browning. Once fully melted, reduce the heat to low.

Step 2: Add Marshmallows and Pumpkin

Stir in the mini marshmallows and pumpkin puree. Mix continuously until the marshmallows are completely melted and the mixture is smooth. This is the sticky base that will coat your cereal.

Step 3: Season It Up

Sprinkle in the pumpkin pie spice and vanilla extract. Stir well to make sure everything is evenly incorporated. At this stage, the aroma will smell like a pumpkin candle in the best way possible.

Step 4: Mix In the Cereal

Remove the pot from heat and add in the Rice Krispies. Stir with a spatula until every piece is coated in the marshmallow mixture.

Step 5: Press and Cool

Transfer the mixture to a greased 9×13-inch baking dish. Lightly press it down using a buttered spatula or wax paper. Let it cool for at least 30 minutes before slicing into squares.

How to Store and Serve These Cozy Treats

These treats feed about 12 people, depending on how big you cut them. Once set, they’re easy to wrap individually for lunchboxes or wrap the whole tray for parties.

To store them, just keep them in an airtight container at room temperature. They stay fresh for up to four days. You can refrigerate them to extend the life, but they’ll be firmer—just let them sit out for a few minutes before serving.

They’re best served with a cup of hot cider, warm milk, or pumpkin spice latte if you’re feeling extra seasonal. And they hold up beautifully on a dessert table next to pies, cookies, and brownies.
