Creating this Classic Apple Pie with Crumble Topping is a fun experience when you follow these simple steps:

1. Prepare the Pie Crust: In a large bowl, mix flour, salt, and sugar. Add the cold, cubed butter and cut it into the flour mixture until it resembles coarse crumbs. Gradually add ice water until the dough comes together. Divide the dough in half, shape it into disks, wrap in plastic, and chill for at least 30 minutes.

2. Preheat the Oven: Preheat your oven to 425°F (220°C).

3. Prepare the Apple Filling: In a large bowl, combine sliced apples, sugar, lemon juice, cinnamon, nutmeg, and flour. Set aside to let the flavors meld.

4. Roll Out the Dough: On a floured surface, roll out one disk of chilled dough to fit a 9-inch pie plate. Carefully place the rolled crust into the pie plate.

5. Fill the Crust: Pour the apple filling into the prepared crust, spreading it evenly.

6. Make the Crumble Topping: In a separate bowl, combine flour, oats, brown sugar, and cinnamon. Drizzle melted butter over the mixture and stir until it forms clumps.

7. Assemble the Pie: Evenly distribute the crumble topping over the apple filling in the pie.

8. Bake: Place the pie in the preheated oven and bake for 15 minutes. Lower the oven temperature to 350°F (175°C) and continue to bake for an additional 35-45 minutes, or until the apples are tender and the topping is golden.

9. Cool: Once baked, remove the pie from the oven. Allow it to cool for at least 15 minutes before slicing.

10. Slice and Enjoy: Cut into slices and serve warm or at room temperature.

By following these steps, you’ll create an incredible Classic Apple Pie with Crumble Topping that will delight your family and friends!
