Creating this amazing Reese’s Cheesecake is simple if you follow these steps:

1. Preheat your oven to 325°F (160°C). Grease a 9-inch springform pan and set aside.

2. Make the crust: In a medium bowl, combine the Oreo cookie crumbs, melted butter, and granulated sugar. Mix until well combined. Press the mixture firmly into the bottom of the prepared springform pan.

3. Bake the crust: Place the crust in the preheated oven and bake for 10 minutes. Remove and allow to cool while you prepare the filling.

4. Prepare the filling: In a large mixing bowl, beat the softened cream cheese and granulated sugar together until smooth and creamy.

5. Add peanut butter: Mix in the creamy peanut butter until fully incorporated. Scrape down the sides of the bowl as needed.

6. Incorporate eggs: Add the eggs one at a time, mixing well after each addition. Be careful not to overmix.

7. Add vanilla and sour cream: Stir in the vanilla extract and sour cream until the mixture is smooth and well combined.

8. Pour the filling: Carefully pour the cheesecake filling over the cooled crust in the springform pan. Smooth the top with a spatula.

9. Bake the cheesecake: Bake in the preheated oven for 55-60 minutes. The edges should be set, but the center may still be slightly jiggly.

10. Cool gradually: Turn off the oven and crack the door open. Allow the cheesecake to cool in the oven for about 1 hour to prevent cracking.

11. Chill: After cooling, refrigerate the cheesecake for at least 4 hours or overnight for best results.

12. Prepare the topping: In a small saucepan, heat the heavy cream over medium heat until just simmering. Remove from heat and add the semi-sweet chocolate chips. Stir until melted and smooth.

13. Drizzle the topping: Pour the chocolate ganache over the chilled cheesecake and spread it evenly.

14. Garnish: Sprinkle the chopped Reese’s Peanut Butter Cups on top for an extra special touch.
