Ingredients Equipment Method Notes

Ingredients
  

  • 1 tsp nonstick cooking spray for the pan
  • 0.5 cup pumpkin puree canned, not pumpkin pie filling
  • 4 tbsp unsalted butter
  • 0.5 tsp pumpkin pie spice
  • 0.25 tsp fine salt
  • 1 package (12 oz) miniature marshmallows
  • 1 tsp vanilla extract
  • 6 cup crisp rice cereal
  • 1 cup graham cracker crumbs

Equipment

  • 1 9x13-inch baking pan

Method
 

  1. Line a 9x13-inch baking pan with parchment paper, leaving enough overhang to lift out the treats.
  2. Lightly coat the parchment with cooking spray.
  3. Put the pumpkin puree in a 4-quart saucepan over medium-low heat and cook, stirring often, for 5 to 7 minutes, until thickened and reduced to about 1/4 cup.
  4. Add the butter, pumpkin pie spice, and salt; stir over low heat until the butter melts, about 1 minute.
  5. Add the marshmallows and stir over low heat for 3 to 4 minutes, until melted and smooth.
  6. Remove from the heat and stir in the vanilla.
  7. Combine the cereal and graham cracker crumbs in an 8-quart bowl.
  8. Pour the marshmallow mixture over the cereal and crumbs, then fold until evenly coated.
  9. Transfer the mixture to the prepared pan and gently press it into an even layer with a lightly greased spatula.
  10. Let the treats set at room temperature for about 1 hour, until firm enough to cut.
  11. Lift the treats from the pan and cut into 16 squares.

Notes

For the best texture, cook the pumpkin until it is thickened and reduced to about 1/4 cup. Store airtight at room temperature for up to 3 days or refrigerate for up to 5 days; freeze for up to 2 months. For a dairy-free option, use dairy-free butter and vegan marshmallows.
