Ingredients

Graham Cracker Crust or use Store-bought Graham Cracker Crust

  • ½ cup unsalted butter
  • 12 graham crackers
  • 2 tablespoons granulated sugar
  • ¼ teaspoon kosher salt

Chocolate Pie Filling

  • 1 ½ cups mini marshmallows
  • 1 cup cold heavy cream divided
  • ¼ teaspoon salt
  • 1 cup semi-sweet chocolate chips
  • 1 tablespoon granulated sugar

Peanut Butter Pie Filling

  • ¾ cup creamy peanut butter
  • 4 ounces cream cheese
  • cup powdered sugar
  • 1 tablespoon vanilla extract
  • ¼ teaspoon salt
  • ¾ cup cold heavy cream

Garnishes

  • mini peanut butter cups
  • peanut butter or peanut butter chips, melted and drizzled on top

Instructions

Graham Cracker Crust or Use Store-bought

  • Place unsalted butter in a large microwave-safe bowl, until just melted, about 40 seconds.
  • Process graham crackers until finely ground in food processor.
  • Add the butter, 2 tablespoons granulated sugar, and 1/4 teaspoon salt and combine.
  • Transfer the mixture to a standard 9-inch pie pan. Using a flat-bottomed measuring cup, press it evenly into the bottom and about 1 inch up the sides. Refrigerate while you make the fillings.

Chocolate Pie Filling

  • Place 1 1/2 cups mini marshmallows, ¼ teaspoon salt and 1/4 cup of the heavy cream (reserving ¾ cup for later) in a large microwave-safe bowl. Microwave on HIGH in 30-second bursts, stirring between each, until the marshmallows are mostly melted, about 1 minute total.
  • Immediately add 1 cup semi-sweet chocolate chips. Stir until the chocolate is melted and smooth. Set aside to cool to finish up after making the peanut butter filling.

Peanut Butter Pie Filling

  • In a food processor or mixer, add 3/4 cup creamy peanut butter, 4 ounces cream cheese, 1/3 cup powdered sugar, 1 tablespoon vanilla extract, and 1/4 teaspoon salt in the food processor. Mix/process until well combined, about 1 minute.
  • Add 3/4 cup cold heavy cream and mix/process until smooth and thick, 30 to 45 seconds, making sure not to overmix/overprocess.
  • Transfer 3/4 cup to to ziplock bag or pastry bag fitted with a star pastry tip and reserve for garnish.
  • Transfer the remaining peanut butter filling into the chilled crust and spread into an even layer. Refrigerate while you finish preparing the chocolate filling.

Finishing the Chocolate Pie Filling

  • Place the remaining 3/4 cup cold heavy cream and 1 tablespoon granulated sugar in a large bowl and whisk until stiff peaks form, about 2 minutes.
  • Transfer 1/4 of the whipped cream into the cooled chocolate mixture and stir to mix in. Add the remaining whipped cream and gently fold just until no streaks of cream remain.
  • Transfer the chocolate filling over the peanut butter filling and spread into an even layer.
  • Pipe the reserved peanut butter filling decoratively around the border of the pie.
  • Optional: Add mini peanut butter cups if desired.
  • Refrigerate uncovered until the filling is set, at least 6 hours or up to overnight.
  • Optional: Melt peanut butter or peanut butter chips and drizzle on top of pie before serving.

Notes

Leftover pie can be covered with plastic wrap and refrigerated for up to 5 days.
