Add the remaining ingredients and blend until mixed.
Spread out the tart shells onto a cookie sheet, you might need two.
Using a 1/4 measuring cup, spoon the pumpkin filling into each tart shell. I find the perfect amount for each shell to be just a little less than 1/4 cup, so it's a good way to keep them even and ensure you have enough filling for the shells.
Bake at 375F for about 30 minutes or until crust starts to golden.
Let cool and dollop whipped topping onto each with a sprinkle of cinnamon. OR, freeze them once cooled {in an airtight container} and take them out to enjoy as needed.
Notes
StorageStore at room temperature for up to 2 hours. After that, they need to be refrigerated in an airtight container for up to 4 days. To freeze, let them cool completely then wrap each pie individually in plastic wrap and place in a freezer bag. They will keep for up to 2 months. Thaw overnight in the refrigerator before serving.
