Preheat the oven to 325°F, line a 9×13 pan, mix the crust ingredients, press firmly into the pan, bake for 10 minutes, and let cool slightly.
Beat the cream cheese until smooth, add sugar, then mix in the eggs one at a time. Add sour cream, vanilla, flour, and salt, blending until fully smooth.
Pour the filling over the crust, smooth the top, bake for 30–35 minutes until the edges are set and the center jiggles, then cool for 1 hour.
Make caramel by melting sugar until amber, whisking in butter and cream, letting it cool for 10 minutes, then spreading over the cheesecake.
Chill for 2–4 hours or overnight, lift out using the parchment, and slice with a hot knife.
