Ina large bowl, stir together the pumpkin, instant vanilla pudding mix, pumpkin pie spice, cinnamon, and vanilla extract until the pudding is dissolved.
Add the whipped topping to the bowl and fold in until well combined.
Cover the bowl and place it in the refrigerator to chill for at least one hour before serving.
Serve with cookies or graham crackers for dipping or transfer to individual serving bowls and top with whipped cream.
Notes
The pumpkin fluff should be kept in refrigerator until you’re ready to eat it. Transfer any leftovers to an airtight container or cover the bowl with plastic wrap and store in the refrigerator for up to 3 days.
