Preheat the oven to 375 Degree F.
On a lightly floured surface, roll the dough into 9 inch circle and place it on greased pie dish. Trim any extra edges. You can either discard or make some leaves using cookie cutter and design your pie.
Using pie weights, blind bake the crust for 10 minutes.
Pour the pumpkin pie filling into pre-baked crust. Make sure you pour only ¾ of of the way up. (You can make another pie or mini pie using remaining filling or these mini pumpkin pancake bites). Bake for about 50 minutes. (You can cover your crust with aluminium foil at 25 minute mark to avoid it from turning brown) While the pie is baking, in a small bowl, mix oats, sugar, butter, and almonds until crumbly and set aside.
After 50 minutes, sprinkle the streusel topping and continue baking for another 10 to 15 minutes. Check if it is done every 5 minutes. Do not overbake as it will make your pie crack.
Allow the pie to cool down completely for about 2 to 3 hours.
Pumpkin Pie with Streusel Topping is ready. Slice, Serve and Enjoy.
