This is my Original Fluffernutter Pie – a no-bake dessert I created and published in 2023. It combines a creamy marshmallow filling with a rich peanut butter topping in a buttery graham cracker crust. Inspired by the classic New England fluffernutter sandwich, this pie has become one of my favorite easy desserts.
Over the years Iโve developed many fluffernutter treats (cookies, bars, brownies, and more), but this pie remains a standout because itโs simple, crowd-pleasing, and requires no oven time.

Ingredients & Substitutions
Crust: When testing this pie, the graham cracker crust was the most popular vote when it came to the crust. Make sure the melted butter completely coats the crumbs; you don’t want any of that left behind on the plate! You could also use a store-bought crust.
Heavy Cream: Look for heavy cream, also known as heavy whipping cream. This is a liquid with 36-40% fat and will be whipped up into a cream to use in the marshmallow filling.
Marshmallows: You will need 3 cups of mini marshmallows for the filling. Or, use about 24 regular-sized marshmallows.
Milk: For the creamiest filling, use whole milk. However, you could use milk with less fat, like 2%, but the filling may not be quite as creamy.
Peanut Butter: To go along with ultra creamy marshmallow filling, I used creamy peanut butter. But you could also use the crunchy variety for a nutty crunch to each bite.

What Is A Fluffernutter?
A fluffernutter is a sandwich that is made with peanut butter and marshmallow creme (fluff) in between slices of white bread. The combination of marshmallows and peanut butter is perfect for more than just sandwiches, for sure! In fact, once I tasted the cookies, I went ahead with Fluffernutter Bars, Fudge, and Fluffernutter Rice Krispie Bars! And now, I added this no-bake dessert!

Can I Make Fluffernutter Pie Into Individual-Sized Portions?
Sure! A cute way to serve fluffernutter pie would be to make it into smaller portions. You could use ramekins, special bowls, small pie tins, or even a muffin tin! Just make sure they are suitable for assembling and chilling the dessert. Simply divide the crust evenly between your choice of serving vessels. Then top with the marshmallow filling and melted peanut butter. Chill the desserts in the refrigerator until set.

Notes from My Kitchen
After testing many variations, I found that melting the marshmallows with milk creates the perfect light, fluffy texture. The pie holds up beautifully in the fridge and is best served cold. For a fun twist, you can use chocolate graham crackers or add a thin layer of chocolate ganache under the peanut butter.

How To Store Fluffernutter Pie
Store fluffernutter pie in the refrigerator, covered. It will last up to 3-4 days.

Fluffernutter Pie
Ingredients
Filling
- 3 cups (150 g) mini marshmallows
- ยฝ cup (122.5 g) whole milk
- 1 ยฝ cups (357 g) heavy cream
Crust
- 1 ยฝ cups (126 g) graham cracker crumbs, about 10-12 graham cracker sheets, crushed
- ยฝ cup (1 stick / 113 g) unsalted butter, melted
Topping
- ยฝ cup (129 g) creamy peanut butter, melted
Instructions
Filling
- To a saucepan over low heat, add marshmallows and milk. Stir constantly until the marshmallows are melted and the mixture is combined. Remove from heat and let cool completely (about 30 minutes).
- While the marshmallow is cooling, add heavy cream to a mixing bowl. Using an electric mixer, start mixing at the lowest speed, and then gradually increase the speed to medium until the cream starts to get thicker (soft peaks). (The gradual progression prevents you from spraying yourself with cream.)
- Gently fold in the cooled marshmallow mixture. Set aside while you prepare the crust.
Crust
- In a small bowl, combine graham cracker crumbs and melted butter. Make sure to get every crumb coated with butter.
- Pour the crumbs into a deep 9-inch pie pan, pressing it into the bottom and up the sides.
- Evenly spoon the marshmallow mixture over the crust.
- Put the melted peanut butter into a pastry bag (or a plastic zipper bag with a corner cut off). Drizzle the peanut butter across the top of the marshmallow mixture. (Or you can carefully spread it with a kitchen knife.) Gently spread it out into an even layer.
- Chill the pie in the refrigerator for 2 hours (or until set), up to overnight. Serve chilled.
