Mix the graham cracker crumbs with sugar and melted butter until everything is damp. Push the mix firmly into the bottom of a 9-inch springform pan. Pop it in the oven at 350°F for 8 minutes, then let it cool all the way down.

Beat the softened cream cheese in a big bowl till it's nice and smooth. Drop in the sugar and vanilla, then mix everything together well. Add eggs one at a time, mixing slowly and scraping the bowl sides after each one. Gently fold the sour cream in until you can't see any streaks.

Pour your cream cheese mix over the cooled crust. Use a spatula to flatten the top, then put it aside for now.

Toss chopped apples with brown sugar and cinnamon in a pot. In a separate small bowl, mix cornstarch with water until it dissolves, then add to your apple mix along with lemon juice. Cook everything on medium heat, stirring now and then, until the apples get soft and the sauce thickens up. Let it cool a bit.

Spread the cooled apple mix evenly on top of your cream cheese layer.

Combine flour and brown sugar in a bowl. Add the cold butter chunks and rub them in with your fingers or a pastry tool until you get a crumbly mix that looks like coarse breadcrumbs.

Sprinkle the crumble mix all over the apple layer. Put your springform pan inside a bigger baking dish, then pour hot water into the outer dish until it comes halfway up the sides of your pan. Bake at 350°F for about 30-45 minutes, or until the middle looks mostly set but still jiggles slightly.

Let your cheesecake cool down to room temp, then stick it in the fridge for at least 4 hours. Overnight chilling works even better for clean slices.
