Creating Pumpkin Spice Mini Tarts is a delightful process. Follow these easy steps to bring these treats to life:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Make the Crust: In a mixing bowl, combine flour, sugar, and salt. Cut in the chilled butter until the mixture resembles coarse crumbs. Gradually add cold water, mixing until the dough forms.
3. Roll Out the Dough: On a lightly floured surface, roll out the dough to about 1/8-inch thick. Cut into circles to fit mini tart pans.
4. Fit the Dough into Pans: Press the dough circles into the prepared mini tart pans, making sure to cover the sides and bottom.
5. Pre-bake the Crusts: Place the tart shells in the preheated oven and bake for 10-12 minutes until lightly golden. Remove and set aside to cool.
6. Prepare the Filling: In a large bowl, whisk together the pumpkin puree, heavy cream, eggs, brown sugar, cinnamon, nutmeg, ginger, cloves, vanilla extract, and salt until smooth.
7. Fill the Tart Shells: Pour the pumpkin filling into each pre-baked tart shell, filling them about three-quarters full.
8. Bake the Tarts: Return the filled tarts to the oven and bake for an additional 15-20 minutes, or until the filling is set and a toothpick inserted in the center comes out clean.
9. Cool the Tarts: Once done, remove the tarts from the oven and allow them to cool in the pans for about 15-20 minutes before transferring to a wire rack to cool completely.
10. Serve and Enjoy: Top with whipped cream and a sprinkle of ground cinnamon if desired.
