In a large mixing bowl, combine the pumpkin puree, vanilla pudding mix, and pumpkin pie spice. Stir until well blended.
2. Fold in the Whipped Topping
Gently fold in the whipped topping until fully incorporated and the mixture is light and fluffy. If you want a sweeter fluff, add ½ cup powdered sugar and mix until combined.
3. Chill
Cover the bowl and refrigerate the pumpkin fluff for at least 1 hour to allow the flavors to meld and the mixture to set.
4. Serve
Serve chilled with graham crackers, apple slices, vanilla wafers, or pretzels for dipping.
