Prepare the Crust: In a mixing bowl, combine the chocolate graham cracker crumbs and melted butter until well combined. Press the mixture firmly into the bottom of a 9-inch springform pan to create an even crust. Chill in the refrigerator while you prepare the filling.
Make the Cheesecake Filling: In a large mixing bowl, beat the softened cream cheese and creamy peanut butter together until smooth and creamy. Gradually add powdered sugar and continue to beat until thoroughly combined. Stir in vanilla extract.
Whip the Heavy Cream: In another bowl, whip the heavy cream until it forms stiff peaks. Gently fold the whipped cream into the peanut butter mixture, being careful not to deflate the cream.
Layer the Cheesecake: Pour the peanut butter cheesecake filling over the chilled crust in the springform pan. Use a spatula to smooth the top. Refrigerate for at least 4 hours or until the cheesecake is set.
Prepare the Chocolate Ganache: In a small saucepan over low heat, melt the semi-sweet chocolate chips. Stir until smooth and let it cool slightly. Drizzle the ganache over the set cheesecake, allowing it to cascade down the sides.
Garnish and Serve: If desired, sprinkle chopped peanuts on top for an extra crunch. Carefully remove the cheesecake from the springform pan and slice into wedges to serve.
Notes
Serve slices on individual plates with a drizzle of extra chocolate ganache and a sprinkle of chopped peanuts for an elegant touch.
