Preheat oven to 325°F (163°C). Mix graham cracker crumbs, melted butter, and brown sugar until combined. Press into a 9-inch springform pan and bake for 8–10 minutes until golden. Let cool.
Beat softened cream cheese until smooth. Add brown sugar, granulated sugar, and mix until creamy. Add eggs one at a time, mixing well after each. Stir in vanilla extract, heavy cream, and fold in chopped toasted pecans.
Pour the cheesecake filling over the cooled crust. Smooth the top with a spatula.
Bake for 55–65 minutes until set but slightly jiggly. Turn off the oven, crack the door, and let cool for 1 hour. Refrigerate for at least 4 hours, or overnight.
Melt butter and brown sugar in a saucepan over medium heat for 2–3 minutes until thickened. Stir in heavy cream and vanilla, then add toasted pecans and cook for another minute. Let cool.
Pour cooled pecan praline topping over the chilled cheesecake. Spread evenly, slice, and serve! Enjoy the rich, nutty goodness.
