Preheat the oven to 325°F.
In a medium bowl, combine graham cracker crumbs, melted butter, and 1/4 cup sugar. Mix until well combined.
Press the mixture firmly into the bottom of a 9-inch springform pan to form the crust. Bake for 10 minutes, then remove from the oven and let cool.
In a large mixing bowl, beat the softened cream cheese with 1 cup of sugar until smooth and creamy.
Add the eggs one at a time, mixing well after each addition.
Stir in the vanilla extract, sour cream, and salt until fully incorporated.
Fold in the toasted pecans and 1 cup of caramel sauce.
Pour the cheesecake filling over the cooled crust in the springform pan.
Bake the cheesecake for 55-60 minutes, or until the center is set but still slightly jiggly.
Turn off the oven, crack the door, and let the cheesecake cool in the oven for 1 hour.
Remove from the oven and refrigerate for at least 4 hours, preferably overnight.
Before serving, drizzle additional caramel sauce over the top and sprinkle with extra chopped pecans if desired.
