Prepare the Pecan Graham Crumb Crust:

• Preheat the oven to 325°F (160°C).
• Grease a 9-inch springform pan and line the bottom with parchment paper.
• In a bowl, mix the pecans, graham cracker crumbs, brown sugar, cinnamon, and melted butter until evenly combined.
• Press the mixture into the bottom of the pan to form an even crust.
• Bake for 10 minutes, then let it cool while preparing the cheesecake filling.

Make the Cheesecake Filling:

• In a large bowl, beat the cream cheese, white sugar, and brown sugar until smooth and creamy.
• Add the cinnamon and cornstarch and mix until fully incorporated.
• Add the sour cream and vanilla extract, mixing until smooth.
• Beat in the eggs one at a time, being careful not to overmix.
• Pour the cheesecake batter over the cooled crust, smoothing the top with a spatula.

Bake the Cheesecake:

• Place the springform pan in a larger roasting pan. Fill the roasting pan with hot water until it reaches halfway up the sides of the springform pan to create a water bath.
• Bake for 55–65 minutes, or until the edges are set but the center has a slight jiggle.
• Turn off the oven and let the cheesecake cool inside with the door slightly open for 1 hour.
• Remove the cheesecake from the oven, cool to room temperature, and refrigerate for at least 4 hours (preferably overnight).

Make the Pecan Pie Topping:

• In a medium saucepan, melt the butter over medium heat.
• Add the brown sugar, heavy cream, vanilla extract, corn syrup, and cinnamon. Cook until the mixture starts to bubble, then simmer for 2–3 minutes, stirring frequently.
• Remove from heat and stir in the pecan halves. Allow the topping to cool slightly.

Assemble the Cheesecake:

• Spoon the pecan pie topping evenly over the chilled cheesecake, letting the gooey caramel cascade down the sides.
• Chill the assembled cheesecake for an additional 30 minutes to set the topping.

Slice and Serve:

• Carefully remove the sides of the springform pan. Slice into portions using a sharp knife, cleaning it between each cut for a neat presentation. Serve chilled and enjoy!
