Ingredients

Scale
  • 45 whole Oreos
  • 8 tablespoons salted butter, melted
  • 1/2 cup heavy cream (very cold)
  • 24 ounces cream cheese (softened at room temperature)
  • 1 1/2 cups powdered sugar
  • 1 cup creamy peanut butter
  • 3/4 cup sour cream (full-fat, room temperature)
  • 1 teaspoon vanilla extract
  • 1 cup semi-sweet chocolate chips (coarsely chopped)
  • 1/3 cup heavy whipping cream
  • Optional: Chopped Reese’s, chopped peanuts, peanut butter drizzle

Instructions

  1. Place Oreos in a food processor and pulse until fine crumbs form. Mix with melted butter until evenly combined.
  2. Press mixture into a 9-inch springform pan and 1 inch up the sides. Chill in the refrigerator while preparing the filling.
  3. In a bowl, beat heavy cream until stiff peaks form. Set aside.
  4. In a separate bowl, beat softened cream cheese until fluffy. Add powdered sugar and blend until smooth.
  5. Add peanut butter, sour cream, and vanilla extract. Beat until combined and creamy.
  6. Fold whipped cream into the peanut butter mixture until fully incorporated.
  7. Pour filling into the crust, spread evenly, and refrigerate for at least 4 hours or until firm.
  8. To make ganache, heat heavy cream in the microwave until simmering. Pour over chocolate chips and let sit 2-3 minutes.
  9. Whisk until smooth. Let cool slightly, then pour over cheesecake. Spread evenly and chill for 30 minutes.
  10. Garnish with chopped Reese’s, peanuts, or peanut butter drizzle before serving.

Notes

  • Use regular creamy peanut butter, not natural types, to avoid oil separation.
  • Let cream cheese and sour cream come to room temperature for a smooth filling.
  • Freeze wrapped slices for up to 3 months; thaw overnight in fridge before serving.
  • For a different flavor, use peanut butter sandwich cookies instead of Oreos.
  • Chill overnight for best texture and clean slices.
