Preheat oven to 175°C. In a medium bowl, mix graham cracker crumbs, sugar, and melted butter until blended. Press mixture firmly into the base of a 23-centimetre springform pan to form an even layer. Bake for 8–10 minutes, then allow to cool slightly while preparing the filling.

In a large mixing bowl, beat softened cream cheese on medium speed until smooth. Add peanut butter and sugar; continue blending until fully incorporated. Mix in sour cream, eggs, and vanilla extract on low speed just until combined. Take care not to over-mix to avoid cracks during baking.

Pour the filling over the cooled crust and smooth the surface with a spatula. Optionally place the pan in a water bath for gentle baking. Bake for 50–60 minutes, until the edges are set and the centre remains slightly wobbly.

Turn off the oven, slightly open the door, and leave the cheesecake to cool inside for about 1 hour. Remove from the oven, then refrigerate for a minimum of 4 hours or preferably overnight for a firm texture.

In a small heatproof bowl, combine chocolate chips and heavy cream. Microwave in 15-second bursts, stirring until smooth. Drizzle the melted chocolate over the chilled cheesecake. Garnish with chopped peanuts if desired.

Carefully release the cheesecake from the springform pan, transfer to a serving plate, slice, and serve chilled.
