  • Measuring Cups

Ingredients
  

Base Ingredients

  • 3 tbsp butter
  • 10 oz mini marshmallows one standard bag
  • 6 cups rice krispie cereal

Flavor Add-Ins

  • 1 tsp pumpkin pie spice
  • 1 tsp vanilla extract
  • 1/4 cup pumpkin puree optional, adds color and flavor
  • 1 pinch cinnamon

Optional Toppings

  • extra mini marshmallows for topping

Instructions
 

  • Melt the butter: Place the butter in a large pot over medium heat. Let it melt slowly, filling the kitchen with a warm, cozy aroma that sets the mood for the treats.
  • Add the marshmallows: Pour in the mini marshmallows and stir until fully melted. The mixture will become glossy, gooey, and sweet—the perfect base for pumpkin spice flavor.
  • Add the pumpkin spice flavors: Stir in the pumpkin pie spice, vanilla extract, cinnamon, and pumpkin puree (if using). The warm spices will instantly release that signature fall aroma.
  • Mix in the cereal: Turn off the heat and gently fold in the rice krispie cereal. Stir until every piece is coated in the warm, spiced marshmallow mixture.
  • Press into the pan: Line your baking pan with parchment paper. Gently press the mixture into the pan using a buttered spatula, keeping the pressure light so the treats stay soft and chewy.
  • Cool and slice: Let the treats cool for at least 30 minutes before cutting. Enjoy them warm for extra coziness or fully cooled for a firmer texture.
