1-Preheat and Prepare the Pan: First, preheat the oven to 350°F and get a 9-inch springform pan ready by lining it with parchment or foil and wrapping the bottom with foil to stop any leaks. This step ensures your crust holds up well and keeps everything neat.

2-Make the Crust: Mix graham cracker crumbs, ground pecans, brown sugar, and melted butter until crumbly, then press it firmly onto the bottom and sides of the pan, going at least three-quarters up. Bake this for 10 minutes, then set it aside while you reduce the oven to 300°F.

3: Move on to the filling by beating cream cheese until smooth in a mixer, then add sugar, sour cream, vanilla, and salt, mixing well. Gently fold in lightly beaten eggs to keep the texture just right, then spread this over the cooled crust and bake for 40 minutes.

4-Prepare and Add the Topping: While the filling bakes, combine brown sugar, dark corn syrup, rum, and butter in a saucepan, bring it to a boil, and cook for 2 minutes before cooling. Whisk eggs, heavy cream, and salt, then gradually add this to the cooled syrup while stirring. Fold in chopped pecans to coat them evenly.

5: Spoon the pecans over the cheesecake first, then add just enough syrup to fill the crust without overflowing. Pop it back in the oven for 40 to 50 minutes until the top turns golden and crisp. Let it cool on a wire rack, then chill for at least 4 hours or overnight for the best results.

6-Serving Tips: To serve, loosen the sides of the pan carefully, remove the ring, and move the cheesecake to a plate. For neat slices, freeze it for 1 to 2 hours first, then warm your knife under hot water and dry it between cuts. Let slices thaw for about 30 minutes before enjoying. Prep time is about 40 minutes, cook time is around 1 hour 40 minutes, plus chilling, totaling about 6 hours 20 minutes.
