Preheat your oven to 325°F (163°C). In a medium bowl, combine graham cracker crumbs, melted butter, granulated sugar, and salt until fully incorporated. Press this mixture firmly into a greased 9-inch springform pan, forming an even layer. Bake for 8–10 minutes until slightly golden and fragrant. Allow the crust to cool completely while preparing the filling.

In a large mixing bowl, use an electric mixer to beat the cream cheese until smooth and creamy. Slowly add in the peanut butter and granulated sugar, mixing well between additions. Incorporate the eggs one at a time, ensuring each is blended in thoroughly. Follow with the sour cream and vanilla extract, mixing until the filling is completely smooth.

Pour the creamy filling into the cooled crust and smooth the top with a spatula. Bake in the preheated oven for 50–60 minutes, watching as the edges set and the center remains slightly jiggly. Once done, turn off the oven, slightly crack open the door, and let the cheesecake cool inside for about an hour.

In a small saucepan over medium heat, combine the heavy cream and butter, stirring until it starts to simmer. Remove from heat and add chocolate chips, stirring until the mixture is silky and smooth. Let the ganache cool slightly before proceeding to the next step.

Once the cheesecake has cooled completely, carefully pour the chocolate ganache over the top, using a spatula to gently spread it evenly. Chill in the refrigerator for at least 30 minutes, allowing the ganache to set and firm up.

Once set, remove the cheesecake from the springform pan. Slice into pieces and garnish as desired. Enjoy each decadent bite with family and friends!
