📖 Instructions

1. Prepare the Crust: In a medium bowl, mix together the graham cracker crumbs, melted butter, and sugar. Press the mixture firmly into the bottom of a 9-inch springform pan. Bake in a preheated oven at 350°F (175°C) for 8-10 minutes. Let cool completely. Make sure not to burn it, that can happen really fast. Just sayin'.
2. Make the Cheesecake Filling: In a large bowl, beat the cream cheese and sugar until smooth and creamy. Add the eggs one at a time, mixing well after each addition. Stir in the sour cream, vanilla extract, and a pinch of salt. Don't overmix; overmixing can lead to cracks in your cheesecake.
3. Prepare the Apple Filling: In a saucepan, combine the peeled and diced apples, brown sugar, cinnamon, nutmeg, and lemon juice. Cook over medium heat, stirring occasionally, until the apples are softened but still slightly firm, about 8-10 minutes. Let cool slightly.
4. Assemble the Cheesecake: Pour half of the cheesecake filling over the cooled crust. Spoon the apple filling evenly over the cheesecake layer. Top with the remaining cheesecake filling.
5. Prepare the Crumble Topping: In a separate bowl, combine the flour, oats, brown sugar, cinnamon, and cold butter cut into small pieces. Use a pastry blender or your fingers to cut the butter into the flour mixture until it resembles coarse crumbs. Sprinkle the crumble topping evenly over the cheesecake.
6. Bake the Cheesecake: Bake in the preheated oven for 55-65 minutes, or until the edges are set but the center still has a slight jiggle. Turn off the oven and let the cheesecake cool in the oven with the door slightly ajar for 1 hour. This helps prevent cracks. I know, it's hard to resist, but trust me, it's worth it!
7. Chill the Cheesecake: Remove the cheesecake from the oven and let it cool completely at room temperature. Cover with plastic wrap and refrigerate for at least 4 hours, or preferably overnight. This allows the flavors to meld together and the cheesecake to fully set. Or just dig right in while its hot! (Just kidding, don't do that).
8. Serve: Run a thin knife around the edge of the springform pan to loosen the cheesecake. Carefully remove the sides of the pan. Slice and serve. Consider a dollop of whipped cream or a scoop of vanilla ice cream for an extra touch of indulgence. Be sure to savor every single bite!
