    Storage Information

    Refrigerator. Once the pie has fully chilled (for 6 hours or more), wrap it in a layer of plastic wrap. You can also put slices in a single layer in an airtight container. Store it in the refrigerator for up to 5 days.

    Freezer. If you would like to freeze leftover pie (remove any cookie toppings as they tend to have a poor texture when frozen and thawed), pop it in the freezer to set up firmly for a few hours and then wrap it in a double layer of plastic wrap followed by a layer of foil.

    What are fluffernutters?

    A fluffernutter is a sandwich filled with peanut butter on one side and marshmallow fluff on the other. They are delicious!

    Can I make this in a different size/type of pan?

    Yes! You can make this pie in a springform pan instead of a pie pan if you would like. Springform pans are nice because you can just remove the sides when the pie is fully chilled for easy slicing and serving. This recipe would also fit nicely in a 9 inch baking dish.

    I don’t like Cool Whip. What else can I use?

    You can make whipped cream! Beat together 2 cups of chilled heavy cream with ¾ cup powdered sugar on medium speed until stiff peaks form.

    Do I have to have a food processor for the crust?

    Nope! Simply place the cookies in a ziploc bag and use a rolling pin to crush them into fine crumbs. This method requires a bit more effort but less dishes!

    Can this pie be made ahead of time?

    You can! Prepare the recipe from start to finish, allow it to chill in the fridge for at least 6 hours, and then pop it in the freezer for a couple of hours to firm up. Finally, wrap the whole thing in a double layer of plastic wrap. If you already sliced the pie, arrange the slices in a single layer in an airtight container. You can store it in the freezer for up to 3 months. Allow the pie to thaw in the fridge before serving.

    Variations To Try

    • For a chocolate twist, use Oreo cookies for the crust.
    • Top the pie with a drizzle of Hot Fudge, Caramel Sauce or Nutella!
    • Add a layer of bananas in between the peanut butter and marshmallow layers.
    • Considering torching the marshmallows right before serving for an impressive finish.

    Trish’s Tips

    • Ensure the cream cheese is at room temperature for a smoother filling.
    • Chill the crust before adding the filling to prevent it from becoming soggy.
    • Avoid natural peanut butter in this recipe as it can sometimes separate.
    • Plan ahead! This pie needs time to set up so make it a day in advance.
