Preheat the oven to 325°F (163°C). In a bowl, mix graham cracker crumbs and melted butter until combined. Press into the bottom of a 9-inch springform pan to create the crust.
In a large bowl, beat the softened cream cheese and sugar together until creamy and smooth.
Add peanut butter and mix until fully incorporated.
Add eggs one at a time, mixing well after each addition.
Mix in melted chocolate chips, vanilla extract, and salt until smooth.
Pour the filling over the crust in the springform pan.
Bake for 50 minutes or until the center is set but still slightly jiggly.
Let cheesecake cool at room temperature, then refrigerate for at least 4 hours before serving.
Notes
For best results, serve chilled with whipped cream or chopped peanuts on top.
