Description

A fluffy pumpkin pie made with melted marshmallows, pumpkin purée, warm spices, and whipped topping in a prepared graham cracker crust. Prepare it ahead and refrigerate overnight before slicing.


Ingredients

Scale

For the filling

  • 10 ounces (283 g) large marshmallows
  • 1 cup plain pumpkin purée, not pumpkin pie filling
  • 1 teaspoon ground cinnamon
  • ½ teaspoon pumpkin pie spice
  • ½ teaspoon salt
  • 8 ounces (227 g) Cool Whip, thawed according to package directions and kept cold

For the crust

  • 1 prepared graham cracker crust, 6-ounce size

Optional garnishes

  • Whipped cream or additional whipped topping
  • Ground cinnamon
  • Graham cracker crumbs

Instructions

  1. Melt the Pumpkin and Marshmallows.
    Add the marshmallows, pumpkin purée, cinnamon, pumpkin pie spice, and salt to a saucepan. Warm over low to medium-low heat, stirring continuously, until the marshmallows have melted and the mixture is smooth. Remove from the heat.
  2. Cool the Filling Base.
    Transfer to a mixing bowl. Let cool to room temperature, about 30 minutes or longer if necessary, stirring occasionally. The mixture should no longer feel warm before proceeding.
  3. Fold in the Whipped Topping.
    Gently fold the thawed Cool Whip into the cooled pumpkin mixture with a spatula until the color is even and no large white streaks remain.
  4. Fill the Crust.
    Spoon the filling into the prepared graham cracker crust and smooth the top. Cover without touching the surface of the filling.
  5. Chill Until Set.
    Refrigerate for at least 8 hours, preferably overnight. Keep the pie level and refrigerated until ready to serve.
  6. Garnish and Serve.
    Add optional whipped cream, cinnamon, or graham cracker crumbs just before serving. Cut into eight slices, wiping the knife between cuts.

Notes

  • Use one cup of pumpkin purée, not a whole 15-ounce can.
  • Measure marshmallows by weight because package sizes vary. Regular mini marshmallows can be measured to the same weight; marshmallow fluff is not a direct substitute.
  • The main recipe uses an 8-ounce tub of thawed Cool Whip. Do not add milk, pudding mix, or cream cheese.
  • Make the pie the day before serving. Keep covered in the refrigerator and use within 3–4 days of preparation.
  • Conventional marshmallows may contain gelatin. Check ingredient labels before serving to someone with dietary restrictions.
  • The estimated total includes active preparation, cooling, and chilling. Allow more time if the filling takes longer to cool.
