Preheat the Oven: Preheat your oven to 325°F (165°C). Wrap the outside of a 9-inch springform pan with aluminum foil to prevent leaks.

Mix Crust Ingredients: In a medium bowl, combine graham cracker crumbs, sugar, and melted butter until well mixed.

Press into Pan: Press the crumb mixture firmly into the bottom of the prepared pan. Bake for 10 minutes, then remove from the oven and let cool.

Beat Cream Cheese: In a large bowl, beat the cream cheese and sugar until smooth and creamy.

Add Eggs: Beat in eggs one at a time, just until blended. Stir in vanilla extract.

Mix in Sour Cream and Caramel: Fold in the sour cream, then swirl in 3/4 cup of caramel sauce.

Pour over Crust: Pour the filling over the prepared crust, smoothing the top with a spatula.

Bake: Place the springform pan in a large baking pan. Add hot water to the larger pan to come halfway up the side of the springform pan, creating a water bath.

Bake for 55-65 minutes or until the center is just set and the top appears dull.

Cool: Remove the springform pan from the water bath and remove the aluminum foil. Cool the cheesecake on a wire rack for 10 minutes. Loosen the sides from the pan with a knife; cool 1 hour longer. Refrigerate overnight.

Before Serving: Sprinkle the toffee bits evenly over the top of the chilled cheesecake.

Drizzle Caramel: Drizzle additional caramel sauce over the top before serving.

Optional Garnish: Add dollops of whipped cream around the edge for an extra touch of elegance.
