What is a "Fluffernutter"...?

Fluffernutter is the glorious combination of peanut butter and marshmallow cream.

This pie is velvety smooth and creamy and sweet but not overly sweet.  It's rich in peanut-buttery taste with the crunch of chopped peanuts scattered throughout.

Here's how it comes together...

You start out by making a graham cracker crust.  You can make your own or buy an already made crust at the store.

I'd encourage you to make your own, nothing beats a buttery graham cracker crust.  Just look how easy it is to make one...

Place 12 whole graham cracker sheets in a food processor and process.  If you don't have a food processor, crush the crackers the old-fashioned way, with a rolling pin and a zipped top bag.  Pour the crumbs into a bowl and stir in 1/3 cup sugar and 6 tablespoons of butter that has been melted.

Press the graham cracker crumbs into the pie plate. Make sure you pack the crumbs down so that they are tight.  I like to use the bottom of a small measuring cup to do this.

Bake the crust in a 375 degree oven for 15 minutes.

While the crust is baking, heat a jar of the marshmallow fluff and 2/3 cup of heavy cream in a small saucepan.  This makes the marshmallow fluff extra creamy and easier to work with.

Do you know what the difference between Heavy Cream and Whipping Cream is?  Virtually nothing.  They're both pretty much the same, the only difference is the amount of milk fat.  Heavy Cream has slightly more milk fat (around 36%) so it produces a thicker whipped cream.  Whipping Cream has slightly less milk fat (about 30% to 35%) which will yield a lighter whipped cream.  The reason I mention this is because there are times when I'm shopping for Heavy Cream but can only find Whipping Cream or vice versa.  It's okay to use either.

In another mixing bowl, blend together 8 ounces of cream cheese and 3/4 cup of powdered sugar.  Then, add in 3/4 cup of creamy peanut butter, 2 tablespoons of milk and 1/4 cup chopped peanuts.

It may seem like there are quite a few steps to making this peanut butter pie, but it's really easy and it comes together fairly quickly.

Ingredients

GRAHAM CRACKER CRUST

  • 12 cups whole graham cracker sheets (about 1 and 1/2 crumbs)
  • 1/3 cup granulated sugar
  • 6 tablespoons butter, melted

FILLING

  • 7 ounce jar of Marshmallow Fluff
  • 2 2/3 cup heavy cream or whipping cream, divided
  • 8 ounces cream cheese, at room temperature
  • 3/4 cup powdered sugar
  • 3/4 cup smooth peanut butter
  • 2 tablespoons milk
  • 1/4 cup peanuts, chopped
  • Optional toppings: chopped peanuts, whipped cream, chopped or shaved chocolate

Instructions

  • TO MAKE THE GRAHAM CRACKER CRUST
  • Preheat oven to 375 degrees F.
  • Crush the graham crackers in a food processor or zip topped bag. Add the sugar and pulse or mix until blended. Pour the crumbs into a bowl and stir in the melted butter.
  • Pour crumbs into a pie pan and press them evenly along the bottoms and sides.
  • Bake in the oven for 15 minutes. Remove and set aside to cool.
  • TO MAKE THE PIE FILLING
  • Heat marshmallow fluff and 2/3 cup of heavy cream in a saucepan over low heat, stirring constantly. As soon as it is all melted and combined, remove from the heat and set aside to cool.(You may want to pour the marshmallow cream into a bowl and place it in the refrigerator to speed up the cooling process).
  • Pour the remainder of the heavy cream (2 cups) into a mixing bowl and beat cream until stiff. Set aside.
  • Using an electric mixer, beat the cream cheese with the powdered sugar until creamy. Add the peanut butter, milk and chopped peanuts and mix well.
  • Pour the cooled marshmallow mixture into the whipped cream and fold together gently.
  • Pour the marshmallow cream into the peanut butter mixture and fold together gently.
  • Spoon the filling into the pie crust, smoothing out the top. Refrigerate for at least 3 hours. (The longer the pie stays in the refrigerator, the firmer it will become).
  • To serve, spoon additional whipped cream over the top and garnish with chocolate shavings and chopped peanuts, if desired.
