Method
Make the crust
- Heat the oven to 325°F.
- Grease the sides of a 9-inch springform pan and line the bottom with parchment paper.
- Stir the graham cracker crumbs with 5 tablespoons melted butter.
- Press the crumb mixture firmly into the pan bottom.
- Bake for 10 minutes, then set aside to cool.
Make and bake the cheesecake
- Beat the cream cheese until smooth.
- Beat in the granulated sugar, 2 tablespoons flour, and salt.
- Mix in the sour cream and vanilla.
- Beat in the eggs one at a time on low speed.
- Pour the filling over the crust.
- Bake at 325°F for 65 to 80 minutes, until the edges are set, the center jiggles slightly, and an instant-read thermometer inserted in the center reads 160°F.
- Turn off the oven, prop the door open, and let the cheesecake cool in the oven for 1 hour.
- Run a thin knife around the edge.
- Cool completely on a rack.
- Cover the pan and refrigerate for at least 6 hours, or overnight.
Make the crisp topping
- Combine the oats, 1/2 cup flour, 6 tablespoons brown sugar, and 1/2 teaspoon cinnamon.
- Work in 5 tablespoons cold butter until the mixture forms coarse crumbs.
- Toast the mixture in a 10-inch skillet over medium-low heat for 8 to 10 minutes, stirring often, until golden and crisp.
- Transfer to a plate and cool completely.
Make the apple topping
- Melt the remaining 2 tablespoons butter in the skillet over medium heat.
- Add the apples, 2 tablespoons brown sugar, 1 teaspoon cinnamon, and lemon juice.
- Cook for 6 to 8 minutes, stirring, until the apples are tender but still hold their shape.
- Stir the cornstarch with the cold water until smooth.
- Add the cornstarch mixture to the skillet and cook for 1 minute until the juices thicken.
- Transfer the apples to a bowl and cool completely, then refrigerate until chilled.
Assemble and serve
- Release the springform pan.
- Transfer the cheesecake to a serving plate.
- Spoon the chilled apples over the top and scatter on the crisp topping just before serving.
Notes
For the cleanest slices, chill the cheesecake thoroughly and add the crisp topping just before serving so it stays crunchy. Store covered in the refrigerator for up to 4 days; freeze without the toppings, yes. For a gluten-free swap, use gluten-free graham crumbs and a gluten-free 1:1 flour blend.
