Crafting your own Peach Crumble Cheesecake may seem daunting, but following these steps will simplify the process:

1. Preheat the Oven: Begin by preheating your oven to 325°F (160°C).

2. Prepare the Crust: In a medium bowl, combine the flour, rolled oats, brown sugar, cinnamon, and salt. Pour in the melted butter and mix until crumbly. Reserve half of this mixture for topping.

3. Press the Remaining Mixture: In a greased 9-inch springform pan, press down the remaining crumb mixture to form a crust. Bake for 10 minutes and then remove it from the oven to cool slightly.

4. Make the Cheesecake Filling: In a large bowl, beat the softened cream cheese and sugar until smooth. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract and sour cream until fully combined.

5. Add the Peaches: Gently fold in sliced peaches to the cheesecake mixture.

6. Combine with the Crust: Pour the peach cheesecake filling over the pre-baked crust in the springform pan.

7. Top with Crumble: Sprinkle the reserved crumble mixture over the cheesecake filling evenly.

8. Bake: Place the cheesecake back into the oven and bake for 45-50 minutes, or until the edges are set and the center has only a slight jiggle.

9. Cool and Chill: Once baked, remove the cheesecake from the oven and let it cool at room temperature for an hour. Then, transfer it to the refrigerator for at least 1-2 hours or until fully chilled.

10. Serve: Carefully remove the sides of the springform pan. Your Peach Crumble Cheesecake is now ready to be sliced and served!
