Make this easy, creamy no bake peanut butter pie perfect for summer or holidays. You choose between a graham cracker or Oreo crust for this quick dessert.

Ingredients

Scale
  • 1 1/2 cups crushed graham crackers OR 24 Oreo cookies (about 2 cups crumbs)
  • 1/2 cup (1 stick) unsalted butter, melted
  • 1 cup creamy peanut butter
  • 8 ounces cream cheese, softened
  • 1 cup powdered sugar
  • 1 teaspoon vanilla extract
  • 1 1/2 cups heavy whipping cream, cold
  • Optional Topping: Chocolate sauce or peanut butter cups

Instructions

  1. Prepare the crust: If using graham crackers, crush them finely. If using Oreos, remove the filling and crush the cookies.
  2. Mix the crust crumbs with the melted butter until evenly moistened. Press the mixture firmly into the bottom and up the sides of a 9-inch pie plate. Place the crust in the freezer while you prepare the filling.
  3. Make the peanut butter filling base: In a large bowl, beat the creamy peanut butter and softened cream cheese together until smooth. Add the powdered sugar and vanilla extract, mixing until fully combined.
  4. In a separate, clean bowl, whip the cold heavy whipping cream until stiff peaks form.
  5. Gently fold the whipped cream into the peanut butter mixture until no streaks remain and the filling is light and fluffy. Do not overmix.
  6. Spoon the fluffy peanut butter filling into the chilled crust, spreading it evenly.
  7. Chill the pie in the refrigerator for at least 4 hours, or until firm. For faster setting, you can freeze it for 1-2 hours.
  8. Before serving, top with chocolate sauce or chopped peanut butter cups, if desired. Slice and serve cold.

Notes

  • For an Oreo crust, you do not need to add extra sugar to the crumbs.
  • If you prefer a richer, denser filling, substitute half of the heavy whipping cream with 8 ounces of thawed, softened whipped topping (like Cool Whip).
  • This make ahead dessert keeps well in the refrigerator for up to 3 days.
