Fluffernutter Pie in Steps

Step 1: Prepare the Crust

Start by crushing your choice of 11 ounces of Nutter Butter cookies, shortbread cookies, graham crackers, or Golden Oreos into fine crumbs using a food processor or by placing them in a zip-top bag and crushing with a rolling pin. Transfer the crumbs to a bowl and mix in 1/2 cup melted salted butter until the mixture resembles wet sand. Press the crust evenly into the bottom and up the sides of a 9-inch pie dish. Place the crust in the refrigerator to chill while you prepare the filling.

Step 2: Make the Peanut Butter Filling

In a large mixing bowl, beat 8 ounces of softened cream cheese with 1/3 cup granulated sugar until smooth and creamy. Add 1 1/2 cups creamy peanut butter and continue beating until the mixture is well incorporated and fluffy. Next, add 1 cup of the marshmallow fluff and mix thoroughly until smooth and combined.

Step 3: Fold in Cool Whip and Mini Marshmallows

Gently fold 4 ounces (half) of the Cool Whip into the peanut butter mixture using a rubber spatula. Then fold in 1/3 cup mini marshmallows to add a delightful chewiness to the filling. Be careful to fold gently to maintain the airy texture.

Step 4: Assemble the Pie

Remove the crust from the refrigerator and spoon the peanut butter filling into the crust. Smooth the top evenly with a spatula. In a separate bowl, whip the remaining 4 ounces of Cool Whip with 2 tablespoons powdered sugar until fluffy. Dollop or pipe the remaining 1 cup marshmallow fluff on top of the pie, then spread or swirl it around to create a decorative, cloud-like topping. Finally, spread the sweetened Cool Whip over the fluff layer.

Step 5: Garnish and Chill

Sprinkle the top of the pie with crumbled Nutter Butter cookies for a crunchy and visually appealing finish. Cover the pie with plastic wrap and refrigerate for at least 4 hours or overnight to allow the flavors to meld and the filling to set beautifully.

Better-for-You Options

• Use natural peanut butter with no added sugar or oils for a cleaner taste.
• Swap Cool Whip with homemade whipped cream using heavy cream and a touch of vanilla.
• Choose reduced-fat cream cheese to lower the calorie content without sacrificing creaminess.
• Opt for a whole-grain or gluten-free cookie crust if dietary restrictions require it.
• Reduce sugar amounts slightly or substitute with coconut sugar or maple syrup for more natural sweetness.

Frequent Missteps to Avoid

• Using cold cream cheese: This can cause lumps in the filling. Always soften cream cheese to room temperature before mixing.
• Overmixing the filling: Excessive mixing can deflate the whipped components, resulting in a dense texture.
• Not chilling the crust: Skipping this step can cause the crust to crumble when slicing the pie.
• Folding instead of beating: When incorporating marshmallow fluff and Cool Whip, fold gently to maintain the airy consistency.
• Using salted cookies for the crust: If you prefer a sweeter crust, opt for unsalted shortbread or graham crackers.

Store, Freeze & Reheat

Store your Fluffernutter Pie covered in the refrigerator for up to 3 days. The pie tastes best when served chilled, so no reheating is necessary. If you want to keep it longer, you can freeze the pie (without the crumbled cookie topping) for up to 1 month. Wrap it tightly in plastic wrap and aluminum foil to prevent freezer burn. To serve, thaw overnight in the refrigerator and add fresh cookie crumbs on top before serving.

Handy Q&A

Can I use crunchy peanut butter instead of creamy?

Yes, you can substitute crunchy peanut butter for creamy, but the texture of the filling will be slightly different with added crunch. It’s delicious either way, just be mindful that the filling may be less smooth.

Is there a substitute for marshmallow fluff?

You can make a homemade marshmallow fluff by whipping egg whites with sugar syrup until stiff peaks form, or use a marshmallow creme alternative available in most stores. Homemade whipped cream can be used, but it won’t replicate the marshmallow flavor exactly.

Can I make this pie ahead of time?

Absolutely! This Fluffernutter Pie actually benefits from resting in the refrigerator for several hours or overnight, allowing the flavors to meld and the filling to set perfectly.

What is the best way to serve this pie?

The pie is best served chilled straight from the refrigerator. For an extra touch, garnish with additional mini marshmallows or a drizzle of melted chocolate just before serving.
