Creating Blueberry Crumble Cheesecake Pie is simple when you follow these easy steps:

1. Preheat the Oven: Preheat your oven to 325°F (160°C).
2. Make the Crust: In a mixing bowl, combine graham cracker crumbs, sugar, and melted butter. Mix until combined. Press the mixture into the bottom of a pie pan to form an even layer.
3. Bake the Crust: Place the pie crust in the preheated oven and bake for about 10 minutes until it is lightly golden. Remove from the oven and set aside to cool.
4. Prepare the Cheesecake Filling: In a large mixing bowl, beat the softened cream cheese and sugar until smooth. Gradually add eggs one at a time, mixing well after each addition. Stir in the vanilla extract and sour cream until fully combined.
5. Add Blueberries: Gently fold in the fresh blueberries, being careful not to break them.
6. Pour Filling Into Crust: Pour the cheesecake filling into the cooled pie crust, smoothing the top with a spatula.
7. Prepare the Crumble Topping: In a separate bowl, combine flour, oats, brown sugar, and cinnamon. Pour the melted butter over the mixture and stir until crumbly.
8. Top the Cheesecake: Sprinkle the crumble topping evenly over the cheesecake filling.
9. Bake the Pie: Return the pie to the oven and bake for 40-50 minutes until the center is set but still slightly jiggles.
10. Cool: Remove the pie from the oven and let it cool to room temperature. Once cooled, refrigerate for at least 2 hours or until chilled and set properly.
11. Serve: Slice the pie into pieces and enjoy!
