If you are using a store-bought pie crust, put it on the counter so it can come up to temperature.
Roll the pie dough into a 9-inch pie dish. Set aside.
In a large mixing bowl, mix the cream cheese, light brown sugar, and powdered sugar. You can use a stand mixer or hand beaters. Mix until ingredients are fluffy.
Add the eggs, one at a time. In between adding each egg, mix well.
Add the heavy cream and stir to incorporate it.
Add the cinnamon, salt, allspice, flour, and vanilla extract. Carefully mix until all ingredients are well incorporated.
Pour the mixture into the prepared pie dish.
Baked in the preheated oven for 30 to 35 minutes until the center is set, but not super firm. The top will just be starting to become golden brown.
Cool the pie completely before serving.
Serve and enjoy!
Notes
The pie is cooked when the center is set, but not firm. So at 30 minutes, carefully shake the pie dish to see if the middle is “wobbly” or set. If it is moving like a thick batter, cook for an additional 5 minutes. When looking at it, the sides of the pie will be set, so you can compare them with the center.
If you have an 8-inch pie pan, don't worry! Fill the pie dish and know you will have leftovers. Find a small, oven-safe baking dish and coat it with cooking spray. Flll it with the leftover cinnamon pie filling. Bake it alongside the pie, it will need less time.
