Apple crumble cinnamon pie

Haiz!! Today is my last day of annual leave, so I woke up early to bake my daughter's fave apple crumble pie for her breakfast; instead of the usual pancake she could have a good warm slice of apple crumble with cold "Haagen dazs" ice-cream. Not sure if I still remember how to makeup, such a drag to go to work.
This warm heartening dessert definitely uplifts your mood a little especially when you complement with vanilla ice cream! Heavenly delicious!!!

Ingredients

-Pastry for single-crust pie (9 inches)
TOPPING:
-1/2 cup sugar
-1/2 cup all-purpose flour
-1/2 cup cold butter, cubed
FILLING:
-1/2 cup sugar
-2 tablespoons all-purpose flour
-1 teaspoon ground cinnamon
-1/2 teaspoon ground nutmeg
-5 small cups chopped peeled tart  apples 

Direction

1. Preheat oven to 400°. 
2. On a lightly floured surface, roll pastry dough to a 1/8-in.-thick circle; transfer to a 9-in. pie plate. 
3. Trim pastry to 1/2-in. beyond rim of plate; flute edge.
4.  Refrigerate while preparing topping and filling.
5. For topping, in a small bowl, mix sugar and flour; cut in butter until crumbly. 
6. For filling, in a large bowl, mix sugar, flour, cinnamon and nutmeg. Add apples and toss to coat. Transfer to pastry-lined pie plate.

8. Bake 10 minutes. Reduce oven setting to 375°. Bake 40-45 minutes or until topping is browned and apples are tender.
