The beauty of this Fluffernutter Pie Recipe lies in its simplicity. Each ingredient not only keeps things straightforward but also plays a crucial role in balancing flavors and creating that irresistibly smooth and airy texture you’ll fall in love with.

3 cups mini marshmallows: These melt down into a sweet, soft base that brings the iconic fluff element to life.
½ cup whole milk: Helps melt the marshmallows evenly, giving a silky consistency without heaviness.
1 ½ cups heavy cream: Whipped to soft peaks, it adds creamy richness and a light, fluffy texture.
1 ½ cups graham cracker crumbs: Provides a slightly crunchy, buttery foundation with nostalgic charm.
½ cup unsalted butter, melted: Ensures the crust holds together with a rich, golden flavor.
½ cup creamy peanut butter, melted: The star topping that adds that classic, nutty, slightly salty flair for which fluffernutter treats are celebrated.

How to Make Fluffernutter Pie Recipe

Step 1: Melt the Marshmallows

Start by gently warming the mini marshmallows and whole milk together in a saucepan over low heat. Stir constantly—it’s the key to melting the marshmallows perfectly without scorching. Once fully melted into a smooth mixture, remove from heat and let it cool completely for about 30 minutes. This cooling step is crucial so the filling sets with the right texture later on.

Step 2: Whip the Cream

While your marshmallow mixture cools, whip the heavy cream. Begin at a low speed using an electric mixer and gradually increase to medium until soft peaks form. This gradual increase keeps your kitchen tidy by preventing cream splashes. The whipped cream adds an airy softness that balances perfectly with the sweet marshmallows.

Step 3: Combine Filling

Carefully fold the cooled marshmallow mixture into the whipped cream. Folding gently keeps the fluff light and airy rather than deflating it. This combo creates the luscious filling that is the heart of your Fluffernutter Pie Recipe.

Step 4: Prepare the Crust

In a small bowl, mix your graham cracker crumbs with the melted butter, ensuring every crumb is coated. This buttered mixture will press together into a perfectly golden, slightly crunchy crust. Use a deep 9-inch pie pan and press the crumbs firmly into the bottom and up the sides—this makes a sturdy base that contrasts beautifully with the soft filling.

Step 5: Assemble and Top

Evenly spoon your marshmallow-cream filling over the crust, spreading it smoothly. Next, drizzle the melted peanut butter across the top. For neatness and control, a pastry bag or a plastic bag with a corner cut off works like a charm. Then, gently spread the peanut butter into an even layer using a kitchen knife. This creamy peanut butter topping is what truly brings this Fluffernutter Pie Recipe full circle.

Step 6: Chill and Set

Refrigerate the assembled pie for at least two hours or up to overnight. Chilling allows everything to set nicely, making each slice neat and ensuring that glorious texture stays intact when served.

Above that is a thick white creamy layer that looks smooth and soft. The top layer is a darker caramel-colored spread that is evenly smoothed over the white layer. On top of the caramel layer, near the cut slice, there are small white marshmallows and some chopped peanuts scattered. One slice is partly removed, and a pie server with a white handle is placed under the slice. In the background, there is a white plate with a piece of pie and a fork resting nearby. The overall look is clean and inviting, with soft natural light. Photo taken with an iphone --ar 4:5 --v 7

Garnishes

Simple garnishes can elevate your Fluffernutter Pie Recipe even more. Consider sprinkling crushed peanuts or graham crackers on top for extra crunch, or add a few mini marshmallows for a playful touch. A light dusting of cocoa powder can also highlight the peanut butter’s richness beautifully.

Side Dishes

Because the pie is rich and sweet, it pairs wonderfully with fresh fruit like sliced strawberries or tangy orange segments to cut through the creaminess. A small scoop of vanilla ice cream or a dollop of lightly sweetened whipped cream on the side balances the richness perfectly, making each bite a delightful experience.

Creative Ways to Present

This Fluffernutter Pie Recipe can be dressed up in many fun ways. You might serve it in individual mini tart pans for charming single servings at parties or drizzle a bit of chocolate ganache over the peanut butter layer for a decadent twist. For a casual gathering, serve it right from the pie dish, inviting everyone to dig in and enjoy the nostalgic flavors together.

Make Ahead and Storage

Storing Leftovers

Any leftover Fluffernutter Pie should be covered tightly and stored in the refrigerator. It will keep its texture and flavor for up to three days, making it a perfect make-ahead dessert for busy days when you want a quick, sweet treat ready to go.

Freezing

If you want to save your pie longer, freezing is an option, although the texture may change slightly. Wrap the pie securely with plastic wrap and aluminum foil before freezing. When ready to enjoy, thaw it overnight in the fridge for best results.

Reheating

This pie is best enjoyed chilled, so reheating isn’t necessary. If you prefer it less cold, simply let it sit at room temperature for 15-20 minutes before serving to soften the peanut butter topping without melting the filling.

FAQs

Can I use crunchy peanut butter instead of creamy?

Absolutely! Crunchy peanut butter adds a lovely texture contrast and makes the pie even more fun to eat. Just melt it gently as described in the recipe, then drizzle and spread as usual.

Is this pie gluten-free?

The crust uses graham cracker crumbs, which typically contain gluten. To make a gluten-free version, substitute with gluten-free graham crackers or another gluten-free cookie crumb that you love.

Can I make this pie vegan?

While this recipe relies on dairy and marshmallows (which often contain gelatin), you can try vegan marshmallows and coconut cream to whip instead of heavy cream. Substituting vegan buttery spreads for the crust can also work, but keep in mind the texture may vary.

How long does the pie take to set properly?

A minimum of two hours in the refrigerator is best for the Fluffernutter Pie Recipe to set, though overnight chilling ensures the smoothest texture and easiest slicing.

Can I add chocolate to this pie?

Yes! Adding a layer of melted chocolate or chocolate chips between the crust and filling or drizzling chocolate on top makes a delicious twist. It pairs wonderfully with the peanut butter flavor and amps up the indulgence factor.

Cook Mode Prevent your screen from going dark

Instructions

Prepare the Filling: Place mini marshmallows and whole milk in a saucepan over low heat. Stir constantly until the marshmallows melt and the mixture combines smoothly. Remove from heat and allow this marshmallow mixture to cool completely, which takes about 30 minutes.
Whip the Cream: While the marshmallow mixture cools, pour the heavy cream into a mixing bowl. Using an electric mixer, begin whipping at the lowest speed, gradually increasing to medium speed until soft peaks form. This gradual increase helps avoid splattering.
Combine Filling Components: Gently fold the cooled marshmallow mixture into the whipped cream until fully incorporated. Set this filling aside as you prepare the crust.
Make the Crust: In a small bowl, combine graham cracker crumbs with the melted unsalted butter, ensuring all crumbs are evenly coated. Press this crumb mixture firmly into the bottom and up the sides of a deep 9-inch pie pan to form an even crust.
Assemble the Pie: Spoon the marshmallow cream filling evenly over the prepared crust, smoothing the top gently.
Add the Peanut Butter Topping: Place the melted peanut butter into a pastry bag or a plastic zipper bag with a corner cut off. Drizzle the peanut butter evenly across the pie’s surface, then carefully spread it into an even layer using a kitchen knife if desired.
Chill and Set: Refrigerate the assembled pie for at least 2 hours or until set. For best results, chill overnight. Serve the pie chilled for a creamy, refreshing dessert.

Notes

Ensure the marshmallow mixture is completely cooled before folding into whipped cream to prevent deflating the cream.
If you prefer a crunchier crust, consider baking the graham cracker crust briefly before assembling (not required for this no-bake recipe).
The peanut butter topping can be substituted with peanut butter cups or chopped peanuts for added texture.
For a more intense peanut flavor, mix a small amount of peanut butter into the filling before folding.
Store leftover pie covered in the refrigerator for up to 3 days.
