Preheat the oven to 350F (180C or 160C on a fan-forced oven).
Wrap the outside of a 9-inch (23-cm) springform pan in tin foil so that the bottom and sides are covered. Wrap it at least 3-4 times so that all the seams are covered too. Lightly grease the pan with non-stick cooking spray.
Notes
For the best flavor, use high-quality salted caramel sauce for the topping.
