Prepare the pie crust according to package instructions or create a dough from flour, butter, salt, and water, rolling it out to fit a mini muffin pan.
Pre-bake the pie crusts in a mini muffin tin at 350°F (180°C) for about 10 minutes until slightly golden.
In a bowl, mix together pumpkin puree, sugar, cinnamon, nutmeg, salt, eggs, and heavy cream until smooth.
Fill the pre-baked crusts with the pumpkin mixture, leaving a little room at the top.
Bake the mini pies for another 15-20 minutes until the filling is set.
Let them cool on a wire rack, serve warm or chilled, and top with whipped cream if desired.
