Ingredients You’ll Need

For the crust:

• 1 ½ cups graham cracker crumbs

• 6 tablespoons melted butter

• 2 tablespoons granulated sugar

For the filling:

• 1 cup creamy peanut butter

• 1 jar (7 oz) marshmallow fluff

• 8 oz cream cheese, softened

• ½ cup powdered sugar

• 1 teaspoon vanilla extract

• 1 ½ cups whipped topping (like Cool Whip), plus more for topping

STEP 1: Make the Graham Cracker Crust

First things first—we need that buttery base to hold all the delicious fluffernutter filling.

In a medium bowl, combine your graham cracker crumbs, melted butter, and sugar. Stir until everything is well mixed and the crumbs look like damp sand. You want every bit of that graham to soak up the butter for maximum flavor and structure.

Now, press the mixture into the bottom and slightly up the sides of a 9-inch pie dish. Use the bottom of a measuring cup or your fingers to press firmly—you want a compact crust that will hold together when sliced.

Once it’s packed in nicely, pop the crust into the fridge to chill while you work on the filling. This step helps the crust set and keeps it firm when the pie is ready to slice later.

STEP 2: Whip Up the Fluffernutter Filling

Here’s where the magic happens.

In a large mixing bowl, beat the softened cream cheese until smooth and creamy. You want to make sure there are no lumps—this will help everything blend together smoothly.

Next, add in the peanut butter, marshmallow fluff, powdered sugar, and vanilla extract. Use a hand mixer or stand mixer on medium speed until the mixture is fluffy, smooth, and fully combined. It should look rich and creamy, and smell like heaven (seriously—peanut butter + vanilla? It’s a dream).

STEP 3: Fold in the Whipped Topping

Now it’s time to lighten things up.

Take your whipped topping and gently fold it into the peanut butter mixture. Don’t stir too aggressively—you want to keep the airiness from the whipped topping to give the filling that fluffy, mousse-like texture.

Once it’s evenly mixed, you’re ready to bring everything together.

STEP 4: Fill and Chill

Spoon the filling into your chilled crust and spread it evenly with a spatula or the back of a spoon. It should fill the pie shell right to the top with a beautiful, creamy layer.

Cover the pie with plastic wrap and refrigerate for at least 4 hours, or until it’s set and firm to the touch. You can also leave it overnight if you’re making it ahead for a party or gathering—it holds up beautifully in the fridge.

Now that your fluffy peanut butter and marshmallow filling is resting comfortably in the fridge, let’s talk about the fun part—toppings, variations, and serving tips that take this No-Bake Fluffernutter Pie from delicious to unforgettable.

One of the best things about this recipe (aside from how easy it is) is how customizable it can be. Whether you like it just the way it is or want to jazz it up with a few fun extras, this pie plays nice with just about any topping or twist you throw its way.

Let’s jump back into the last steps and cover some bonus ideas you can try the next time you whip this up.

STEP 5: Garnish Before Serving

Once your pie has had a good chill—at least 4 hours, or overnight for the best set—it’s time to finish it off and serve.

Right before serving, you can top the pie with an extra dollop (or two) of whipped topping. Spread it gently over the top or pipe it around the edges for a little flair.

Want to go beyond the basics? Here are some simple garnish ideas that pair perfectly with that fluffernutter flavor:

• Crushed peanuts – Add a little crunch and a salty contrast to the sweetness.

• Mini marshmallows – For an extra hit of marshmallow charm.

• Drizzled chocolate – Warm a bit of chocolate sauce and drizzle it over the top in a zigzag pattern.

• Banana slices – A retro twist that brings a fun “Elvis” vibe to the dessert.

You can keep it simple or get creative depending on your mood or occasion. The base is delicious on its own, but these toppings add a personal touch that makes it even more special.

Make-Ahead Tips and Storage

If you’re hosting or bringing dessert to a gathering, this pie is a dream to prep ahead. Just follow the recipe through to the chilling step, and keep it covered in the fridge until ready to serve.

Here are a few extra storage tips:

• Fridge: The pie will stay fresh in the refrigerator for up to 4 days. Just make sure it’s tightly covered with plastic wrap or stored in an airtight container.

• Freezer: Want to make it further in advance? You can freeze this pie! Once set, wrap it well in plastic wrap and then foil. Freeze for up to 1 month. Let it thaw in the fridge overnight before serving.

Just a heads-up: whipped toppings may slightly change texture after freezing, but the taste still holds up beautifully.

Optional Variations to Try

This classic version is perfect as-is, but if you’re feeling adventurous, here are a few flavor variations that still stay true to that fluffernutter vibe:

• Chocolate Graham Cracker Crust: Swap traditional graham crackers for chocolate grahams for a richer base.

• Oreo Crust: Crushed Oreos and melted butter make a chocolatey crust that pairs so well with the peanut butter filling.

• Banana Layer: Before spooning in the filling, lay down thin slices of banana over the crust. It adds a natural sweetness and a nice texture contrast.

• Swirl in Nutella: Gently fold in a few spoonfuls of Nutella to create ribbons of chocolate-hazelnut throughout the pie.

• Crunchy Peanut Butter: If you prefer a bit of texture, substitute half the creamy peanut butter with crunchy. It adds a nice little bite.

These ideas are great if you’ve already made the original version and want to mix things up, or if you’re just looking to surprise guests with a fun flavor combo.

Tips for the Best No-Bake Fluffernutter Pie

Want to make sure your pie turns out perfectly every time? Here are a few tips that I’ve learned after making this dessert more times than I can count:

• Use full-fat cream cheese – It gives the filling the best richness and structure. Low-fat versions can make the filling a bit too soft.

• Soften the cream cheese completely – This helps everything blend smoothly with no lumps.

• Chill thoroughly – Don’t skimp on the chilling time! It helps the filling set properly so you can get clean, beautiful slices.

• Fold gently – When adding the whipped topping, use a folding motion rather than stirring to keep the filling light and airy.

• Use a springform pan (optional) – For a more elegant presentation, a 9-inch springform pan makes it easy to release the pie and serve clean slices.
