This Fluffernutter Pie is a fun and tasty treat! It’s made with layers of creamy peanut butter, sweet marshmallow fluff, and a crunchy graham cracker crust. Yum!
Honestly, how can you resist that combo of peanut butter and fluff? It’s like a nostalgic hug in dessert form! I love serving it chilled for extra deliciousness—perfect for sharing or enjoying solo!
Key Ingredients & Substitutions
Graham Cracker Crumbs: The crust is important for the pie’s base. If you’re out of graham crackers, crushed cookies like Oreos or digestive biscuits work well, too. They provide a different flavor but still taste great!
Creamy Peanut Butter: You can use crunchy peanut butter for added texture, or try almond or cashew butter if you prefer a different nut taste. Just ensure they’re unsweetened for balance!
Heavy Whipping Cream: If you want a lighter option, whipped coconut cream is a nice dairy-free substitute. It adds a tropical twist, too!
Marshmallow Fluff: If you can’t find marshmallow fluff, you can make a quick substitute by mixing powdered sugar, corn syrup, and a bit of vanilla extract until well combined.
How Do I Make Sure My Pie Sets Perfectly?
Setting the pie is crucial for achieving that perfect slice. Here are a few tips:
- Make sure to refrigerate the pie for at least 4 hours, but overnight is even better. This gives the filling time to firm up.
- Use a sturdy pie dish to support your crust and filling. A glass pie dish is ideal for checking the crust’s doneness.
- When mixing the whipped cream into the filling, do it gently to keep the mixture light and fluffy. This helps create that dreamy texture.
Following these steps will ensure every slice is deliciously thick and not runny! Enjoy your pie making!

How to Make Fluffernutter Pie
Ingredients You’ll Need:
For the Crust:
- 1 1/2 cups graham cracker crumbs
- 1/3 cup unsalted butter, melted
- 1/4 cup granulated sugar
For the Filling:
- 1 cup creamy peanut butter
- 8 oz cream cheese, softened
- 1 cup powdered sugar
- 1 1/2 cups marshmallow fluff
- 1 teaspoon vanilla extract
For the Topping:
- 1 cup heavy whipping cream
- Mini marshmallows (for topping)
- Peanut butter drizzle (optional)
How Much Time Will You Need?
This Fluffernutter Pie takes about 30 minutes of preparation time, plus at least 4 hours in the refrigerator to set properly. For the best results, chilling it overnight is recommended. This gives it a deliciously firm texture that makes slicing a breeze!
Step-by-Step Instructions:
1. Prepare the Crust:
Start by preheating your oven to 350°F (175°C). In a mixing bowl, mix the graham cracker crumbs, melted butter, and granulated sugar. Ensure everything is well combined and the crumbs are evenly moistened.
2. Form the Crust:
Next, take the crumb mixture and press it firmly into the bottom and along the sides of a 9-inch pie dish. This will be your delicious crust! Bake it in the preheated oven for about 8-10 minutes, or until it turns a light golden color. Once done, set it aside to cool completely.
3. Make the Filling:
In a large bowl, combine the softened cream cheese and creamy peanut butter. Beat them together until you achieve a smooth and creamy texture. Then add the powdered sugar and vanilla extract, mixing until everything is well incorporated.
4. Fold in the Fluff:
Now, gently fold in the marshmallow fluff into the cream cheese mixture until it’s fluffy and well combined. Be careful not to stir too vigorously—this keeps your filling nice and light!
5. Whip the Cream:
In a separate clean bowl, whip the heavy cream until stiff peaks form. This will give your pie a lovely texture. Once whipped, gently fold the whipped cream into the peanut butter and marshmallow mixture until everything is smooth and fluffy.
6. Assemble the Pie:
Spoon the fluffy filling into the cooled graham cracker crust and spread it evenly. Now it’s time for some fun toppings! Scatter mini marshmallows over the top as you like.
7. Toast the Marshmallows:
If you have a kitchen torch, lightly toast the mini marshmallows until they are golden brown on top. If you don’t have a torch, you can place them under the broiler for just a minute—watch closely to prevent burning!
8. Chill and Serve:
For the final step, refrigerate your Fluffernutter Pie for at least 4 hours, or preferably overnight. This allows the pie to set completely. When ready to serve, drizzle some peanut butter over the top if you like and slice into that heavenly pie. Enjoy every creamy, dreamy bite!
Can I Use Different Types of Peanut Butter?
Yes! You can definitely use crunchy peanut butter for added texture or even almond or cashew butter for a unique flavor. Just ensure they’re unsweetened to maintain the balance of sweetness in the pie!
How Do I Store Leftovers?
Leftover Fluffernutter Pie can be stored in an airtight container in the fridge for up to 3-4 days. Just be sure to cover it well to keep the pie fresh and prevent it from absorbing other flavors in the fridge.
Can I Make This Pie Dairy-Free?
Absolutely! To make a dairy-free version, substitute the cream cheese with a dairy-free alternative and use coconut cream in place of heavy whipping cream. Make sure your marshmallow fluff is also dairy-free.
How Can I Make the Pie Adult-Friendly?
If you’d like to give this pie an adult twist, consider adding a splash of whiskey or coffee liqueur (like Kahlua) to the filling for extra flavor. It adds a nice depth while keeping the treat fun and indulgent!
