No-Bake Peanut Butter Fluff Pie Recipe (Fluffernutter Pie)
This peanut butter fluff pie is the type of dessert that will disappear when you bring it to a potluck or serve it for a backyard barbecue. Folks will be asking for seconds (and thirds!), and you may even get requests for the recipe.
For the graham cracker crust, you can use store-bought pie crust, or you can make your own from scratch, but then you’ll have to turn on the oven, and who wants to do that? Garnish your peanut butter fluff pie with a dollop of homemade whipped cream, roasted peanuts, peanut butter chips, graham cracker crumbs, or even some sliced bananas!
See recipe card below this post for ingredient quantities and full instructions.
- Graham cracker pie crust – You can use a homemade pie crust if you’d like, or an Oreo crust.
For the filling:
- Heavy cream
- Powdered sugar – Also known as confectioners’ sugar.
- Cream cheese – Let this soften to room temperature so it’s easy to whip into a creamy filling.
- Granulated sugar
- Marshmallow fluff
- Creamy peanut butter – Use any brand you like!
For the topping:
- Heavy cream
- Powdered sugar
- Creamy peanut butter
How to Make Peanut Butter Fluff Pie
1. Make Whipped Cream
Add the heavy cream and powdered sugar to the bowl of a stand mixer. Use the whisk attachment to whip the mixture into stiff peaks.
2. Make the Filling
In another large mixing bowl, combine the cream cheese and granulated sugar; beat until the mixture is smooth. Beat in the marshmallow fluff, followed by the peanut butter. Once the mixture is smooth and well-combined, fold in the whipped cream.
Pour the filling into the pie crust and refrigerate for 3 to 4 hours, or until the filling has set.
4. Make the Topping
Whip the heavy cream and powdered sugar as directed in the first step. Warm the peanut butter in the microwave for 20 to 30 seconds, or until it has a pourable consistency that can be drizzled over the pie.
Remove the pie from the refrigerator and pipe or spread the whipped cream over the top. Drizzle this with the peanut butter, then serve.
How to Store Peanut Butter Fluff Pie
This pie can be stored wrapped in the fridge for up two to three days; because it’s made with fresh whipped cream, it won’t last quite as long as if it were made with whipped topping (Cool Whip). If you have leftovers, they can be transferred to an airtight container.
Peanut butter fluff pie can also be frozen for up to 3 months. Wrap it well before storing it in the freezer. Let the pie thaw in the refrigerator, then serve!
The secret to this pie’s light, fluffy texture is the marshmallow fluff! You can find it in the baking aisle of most grocery stores with the other baking ingredients. Beating the filling until it’s light and airy helps, too!
The filling for this pie is made with just a few simple ingredients that are beaten together until they’re light and fluffy. Different peanut butter pie recipes will have different filling ingredients and instructions for making the filling!
There’s 1/2 cup of powdered sugar in the filling for this peanut butter fluff pie, and an additional 3 tablespoons of powdered sugar for the whipped cream topping.
If you want to make a Reese’s peanut butter pie, use Reese’s peanut butter in place of the regular peanut butter called, swap the graham cracker crust for a chocolate crust (or a crust made from Oreos), and drizzle the topping with melted peanut butter and chocolate, or chocolate chips. Mini Reese’s pieces or chopped peanut butter cups are the perfect finishing touch!
