Preheat your oven to 375°F and grease a large baking sheet with cooking spray. Unroll the pie dough on a clean surface. Using a 4-inch round cookie cutter, cut circles out of the crust and place them on the prepared pan. Fold about 1/4 inch of the edge of each circle into the center and crimp the edge. Repeat with the second sheet of pie dough.
In a medium bowl, mix together the pumpkin puree, sweetened condensed milk, vanilla, pumpkin spice, and salt. Spoon the filling into each pie crust.
Bake until the crust is golden and the filling is set, which takes about 20 minutes.
Top with whipped topping and a sprinkle of pumpkin spice before serving. Enjoy your adorable Pumpkin Pie Cookies!
