Preheat your oven to 375°F (190°C).
In a large bowl, combine the pumpkin puree, heavy cream, brown sugar, and granulated sugar.
Add the eggs one at a time, mixing well after each addition.
Stir in the vanilla extract, cinnamon, nutmeg, ginger, and salt until fully combined.
Place the mini pie crusts on a baking sheet.
Fill each crust with the pumpkin mixture, about 3/4 full.
Bake in the preheated oven for 25 minutes or until the filling is set.
Remove from the oven and let cool for 10 minutes.
Serve warm or at room temperature.
Top with whipped cream if desired.
