Preheat your oven to 350°F (175°C).
Roll out the pie crust and cut it into small circles to fit a mini muffin tin.
Press the dough circles into the muffin tin, forming small cups.
In a mixing bowl, whisk together pumpkin puree, heavy cream, brown sugar, granulated sugar, eggs, and vanilla extract.
Add cinnamon, nutmeg, ginger, and salt to the mixture and blend well.
Pour the pumpkin mixture into each pie crust, filling them about 3/4 full.
Bake in the preheated oven for 25-30 minutes, or until the filling is set.
Remove from the oven and let cool completely in the tin.
Carefully remove the mini pies and place them on a serving platter.
Top each pie with a dollop of whipped cream before serving.
