I start by mixing graham cracker crumbs, melted butter, and sugar in a bowl. Press the mixture firmly into the bottom of the springform pan. Chilling it for a few minutes helps it set better before adding the filling.
Next, I beat cream cheese and brown sugar until completely smooth. Then, I add eggs one at a time, followed by vanilla extract and heavy cream. The mixture should be creamy, thick, and free of lumps.
I gently fold in butterscotch and chocolate chips. I try not to overmix so the chips stay whole and create delightful pockets of flavor. A pinch of sea salt at this stage really elevates the taste.
Pour the filling over the prepared crust and smooth the top. Bake at 325°F (163°C) for 50-60 minutes until the edges are set and the center slightly jiggles. I find baking in a water bath helps prevent cracks.
After baking, I let the cheesecake cool at room temperature for an hour. Then, I refrigerate it for at least 4 hours or overnight. This step ensures the cheesecake is firm and slices cleanly.
