Follow these steps to create the amazing Apple Cheesecake Crumb Pie:

1. Prepare the Pie Crust: In a mixing bowl, combine the flour, butter, sugar, and salt until crumbly. Gradually add cold water until the dough comes together. Press into a 9-inch pie pan. Prick the bottom with a fork and refrigerate for 20 minutes.

2. Preheat the Oven: Preheat your oven to 350°F (175°C).

3. Prepare the Apple Filling: In a bowl, mix the sliced apples, brown sugar, cinnamon, and lemon juice. Set aside to allow flavors to meld.

4. Combine Cream Cheese Filling: In another mixing bowl, beat the softened cream cheese until smooth. Gradually add sugar and vanilla, mixing well. Add eggs one at a time until well combined.

5. Assemble the Pie: Take the crust out of the refrigerator. Spread the cream cheese filling evenly over the crust. Layer the apple mixture on top.

6. Prepare Crumb Topping: In a separate bowl, mix flour, oats, and brown sugar. Cut in cold butter until crumbly. Sprinkle the topping over the apple layer.

7. Bake the Pie: Place the pie in the preheated oven and bake for 45-50 minutes or until the apples are tender and the crumb topping is golden brown.

8. Cool the Pie: Once baked, remove the pie from the oven and let it cool for 15-20 minutes before serving.
