Preheat the oven to 325°F (163°C) and grease a 9-inch springform pan.
In a mixing bowl, combine graham cracker crumbs, melted butter, and brown sugar. Press the mixture firmly into the bottom of the pan.
Bake the crust for 10 minutes, then remove from the oven and let cool.
In a large mixing bowl, beat the cream cheese, granulated sugar, and brown sugar until smooth.
Add the eggs one at a time, mixing well after each addition.
Stir in the vanilla extract and 1/2 cup of caramel sauce.
Pour the batter over the cooled crust and smooth the top.
Bake for 50-55 minutes, or until the center is set but slightly jiggly.
Turn off the oven and let the cheesecake cool inside with the door slightly open for 30 minutes.
Refrigerate for at least 4 hours before serving.
Drizzle the remaining caramel sauce over the cheesecake before serving.
Top with whipped cream and chopped pecans for garnish.
