Make the Crust:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9-inch springform pan.
2. Combine Crust Ingredients: In a bowl, mix the graham cracker crumbs, sugar, melted butter, and cinnamon until well combined.
3. Press into Pan: Firmly press the mixture into the bottom of the springform pan to create an even layer.
4. Bake: Bake for 8-10 minutes. Remove from the oven and let it cool while preparing the filling.

Make the Cheesecake Filling:

5. Beat Cream Cheese: In a large bowl, beat the softened cream cheese until smooth and creamy.
6. Add Sugar and Vanilla: Gradually mix in the sugar and vanilla extract until well combined.
7. Add Eggs: Add the eggs one at a time, mixing well after each addition.
8. Incorporate Apple Cider and Spices: Stir in the apple cider, cinnamon, nutmeg, and flour until the mixture is smooth.

Assemble and Bake the Cheesecake:

9. Pour Filling Over Crust: Pour the cheesecake filling over the cooled crust and spread it evenly.
10. Bake: Bake for 55-60 minutes, or until the center is set but still slightly jiggles.
11. Cool Gradually: Turn off the oven and leave the cheesecake inside with the door slightly open for 1 hour to cool gradually.
12. Refrigerate: Let it cool at room temperature, then refrigerate for at least 4 hours (preferably overnight) for the best texture.

Make the Topping:

13. Cook Apples: In a saucepan, combine the diced apples, brown sugar, cinnamon, and lemon juice. Cook over medium heat for 5-7 minutes until the apples are soft and caramelized. Let them cool slightly.
14. Top the Cheesecake: Once the cheesecake is fully chilled, spread the apple topping over the top before serving.

Serving Suggestion:

15. Slice and serve with whipped cream if desired. Enjoy!
