Preheat oven to 325°F (165°C). Grease a 9-inch springform pan.
Mix graham cracker crumbs with melted butter. Press firmly into the bottom of the pan.
Beat cream cheese and sugar until smooth.
Add eggs one at a time, mixing gently after each.
Stir in sour cream, vanilla, and salt until just combined.
Pour filling over crust and smooth the top.
Bake for 50–55 minutes, until edges are set and center slightly jiggles.
Turn off oven, crack the door, and let cheesecake cool inside for 30 minutes.
Remove, cool completely, then refrigerate at least 4 hours before serving.
Add toppings right before slicing.
