In a large bowl, beat 2 of the eggs. Add in the canned pumpkin and combine. Add in the sugar, spices and salt and mix to combine. Last, add in the evaporated milk and stir until fully incorporated. Set aside while assembling pie crusts.
About an hour before baking, take the pie crusts out of the freezer and let come to room temperature. Take crust out of the tin and flatter. Using a 4 inch round cookie cutter, cut out round of dough. You will have left over crust, so taking a rolling pin, add a little flour to your work surface and rolling pie. Roll out the dough to about an 1/8th of an inch, the thickness of the other dough rounds. Repeat the process of cutting out round with the cookie cutter. Carefully mold in the rounds of crust into a cupcake tin that has been sprayed with cooking spray.
Pour in the pumpkin mixture. Take the additional egg and beat, brush the exposed dough with egg. (I used left over dough to cut out leafs/feathers, brush these with egg as well if using.) Bake for 10 minutes, reduce heat to 325 degrees and bake an additional 15 to 20 minutes or until a knife/toothpick inserted into the center comes out clean.
Let cool in the tin completely. Carefully pop out the pies, you may need to run a knife along the edges to get them out. Serve with whipped cream if desired, enjoy!
