Preheat your oven to 350 degrees F. Refrigerate your prepared pie crust until ready to fill and bake.
In the bowl of an electric mixer, add cream cheese and brown sugar. With your paddle attachment, mix for 5 minutes until smooth and combined.
Add in eggs, one at a time, combining fully before adding your next egg. Lastly, mix in your vanilla and maple extract.
Turn off the mixer and add heavy cream, all-purpose flour, cinnamon, kosher salt, ginger, and allspice. Gently mix on low speed until smooth.
Remove your pie crust from the fridge and place it on a large baking sheet pan. This makes it easier to add and remove your pie from the oven.
Pour the filling into your pie shell, add to the oven, and bake for 40 minutes or until the middle of the pie gently jiggles but is not runny. This is similar to making a pumpkin pie.
Let the pie fully cool, cover, and thoroughly chill in the refrigerator for at least 4 hours before serving.
Before serving, top with whipped cream.
Leftovers should be stored in the fridge, covered, for up to 3 days.
