1-First Step: Prepare the Caramel Topping Begin by heating the sweetened condensed milk, unsalted butter, light brown sugar, light corn syrup, and fine salt in a saucepan over medium heat until it starts bubbling. Let it simmer for about 10 minutes until it thickens and turns a rich caramel color. Once done, remove it from the heat and stir in the vanilla extract, then set it aside to cool to room temperature. This step builds the flavorful base that makes your millionaire cheesecake so special, and you can adapt it by using honey if corn syrup isn’t on hand.

2-Second Step: Make the Shortbread Crust Preheat your oven to 350°F and mix the unsalted butter, all-purpose flour, powdered sugar, and fine salt in a bowl until it forms a dough. Press this mixture evenly into a greased springform pan, then prick it with a fork to prevent bubbling. Bake for 22 to 25 minutes until the edges turn golden brown, then let it cool completely. After that, reduce the oven temperature to 300°F and place a tray filled with water on the bottom rack for that helpful moisture during baking. This crust provides a solid foundation and can be tweaked for dietary preferences like gluten-free flour.

3-Third Step: Mix and Bake the Caramel Cheesecake Whisk together the granulated sugar and cornstarch in a bowl to start the filling. In a separate mixer, beat the full-fat cream cheese with this sugar mixture until it’s smooth and creamy. Gradually add the eggs one at a time, followed by the full-fat sour cream, caramel topping, and vanilla extract, mixing on low speed to avoid incorporating too much air. Pour this batter over the cooled crust and bake at 300°F for 20 minutes, then reduce the heat to 225°F and continue baking for 2 hours. Once baked, turn off the oven and let the cheesecake sit inside for another hour, cool it at room temperature, and refrigerate for 3 to 4 hours or overnight. For the best results, use room temperature ingredients to ensure everything blends smoothly, adapting for low-calorie options by choosing lighter cream cheese if desired.

4-Fourth Step: Prepare the Chocolate Ganache Heat the heavy whipping cream in a saucepan until it just begins to bubble, then pour it over the dark or semi-sweet chocolate chips in a bowl. Wait about a minute before stirring until the mixture is smooth and glossy. Add in the unsalted butter, light corn syrup if using, and fine salt, stirring until fully combined. Allow this ganache to cool to room temperature before using it. This step adds a luxurious finish, and you can vary it slightly by choosing different chocolate types based on your taste.

5-Final Step: Assemble and Serve Spread the cooled caramel topping evenly over the chilled cheesecake and let it set in the fridge for 10 minutes. Then, layer on the chocolate ganache and sprinkle with flaky sea salt for garnish. To serve, use a warm knife to cut clean slices, wiping the blade after each cut for neat presentation. The total time for this millionaire cheesecake is about 6 hours and 45 minutes, including prep, cooking, and cooling, making it ideal for planning ahead.
