👩🍳 How to Make Pumpkin Spice Rice Krispie Treats
Making these treats feels like a little moment of peace—you melt, you mix, you stir, and before you know it, you have a pan of warm, cozy pumpkin spice goodness ready to enjoy.
1. Melt the Butter
Start by melting the butter in a large pot over medium heat. As it melts, the kitchen starts filling with warmth, and it sets the tone for the cozy treat you’re about to make.
2. Add Marshmallows
Pour in the mini marshmallows and stir until they melt into a sweet, glossy mixture. This is where the magic really begins—soft, gooey, and so comforting.
3. Add Pumpkin Spice Flavors
Mix in the pumpkin pie spice, vanilla extract, cinnamon, and pumpkin puree (if using). The moment the spices hit the warmth, that signature fall scent fills the air. It’s almost impossible not to smile.
4. Add the Rice Krispies
Turn off the heat and gently fold in the rice krispie cereal until everything is perfectly coated. The mixture will be warm, sticky, and incredibly tempting.
5. Press into a Pan
Line your pan with parchment paper and press the mixture in gently using a buttered spatula. Try not to pack it down too hard—soft pressure keeps the treats fluffy and chewy.
6. Cool and Slice
Let the treats cool for at least 30 minutes before slicing. If you’re like me, you’ll probably grab a warm bite before they’re fully set—and honestly, that’s part of the joy.
