Preheat your oven to 375°F (190°C).
In a large mixing bowl, combine pumpkin puree, heavy cream, and sugars.
Whisk in the eggs and vanilla extract until smooth.
Add the spices: cinnamon, nutmeg, ginger, and salt.
Mix until all ingredients are well incorporated.
Place the mini pie crusts on a baking sheet.
Pour the pumpkin mixture into each crust, filling them about 3/4 full.
Bake in the preheated oven for 25-30 minutes, until filling is set.
Remove from the oven and let cool for 10 minutes.
Serve warm with whipped cream on top.
