In the bowl of a stand mixer with paddle attachment (or in a large bowl and using a hand mixer), cream together the softened cream cheese and the light brown sugar until well blended and creamy, about 2-4 minutes.
Beat in the eggs, then beat in the heavy cream, cinnamon, vanilla, salt, and nutmeg, scraping down the sides and the bottom of the mixer as needed to incorporate all of the ingredients.
Pour the filling into the premade pie crust in pie pan.
Bake at 350°F for 35-45 minutes. The center will still be jiggly, but don't worry: it will continue to set as it cools. It's important not to overbake! The crust edges should be slightly golden brown and the edges of the pie will be slightly set and a little darker.
Allow to cool at room temperature, then cover and chill in the refrigerator for at least 30 minutes.
