Creating the perfect Crème Brûlée Cheesecake can be straightforward if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 325°F (160°C). Prepare a 9-inch springform pan by greasing the bottom and sides.
2. Make the Crust: In a medium bowl, combine graham cracker crumbs, sugar, and melted butter. Mix until well combined. Press the mixture into the bottom of the prepared springform pan evenly.
3. Prepare the Cheesecake Filling: In a large mixing bowl, beat the softened cream cheese until smooth. Gradually add sugar, mixing until well incorporated.
4. Add Flavorings: Mix in the vanilla extract, lemon juice, and cornstarch until combined.
5. Incorporate Eggs: Add the eggs one at a time, mixing on low speed after each addition. Ensure not to overmix.
6. Add Cream and Sour Cream: Slowly pour in the heavy cream and sour cream, mixing until the batter is smooth and creamy.
7. Pour the Filling: Pour the cheesecake filling over the crust in the springform pan, smoothing the top with a spatula.
8. Bake: Place the springform pan in the preheated oven. Bake for about 60 minutes or until the edges are set and the center has a slight jiggle.
9. Cool: Once baked, turn off the oven and leave the cheesecake inside for 1 hour with the door slightly ajar. This helps prevent cracking.
10. Chill: Remove the cheesecake from the oven and refrigerate for at least 4 hours, preferably overnight.
11. Caramelize the Sugar: Before serving, sprinkle an even layer of granulated sugar over the chilled cheesecake. Use a kitchen torch to caramelize the sugar until it’s golden and bubbly.
12. Let it Set: Allow the caramelized sugar to harden for a few minutes before slicing.

Follow these steps carefully to create a stunning Crème Brûlée Cheesecake that will impress everyone!
