Add foil to a 10x15" rimmed baking sheet to line it, then lightly spray it with non stick cooking spray.
Unwrap both the pie crusts and add them to the prepared pan. Cut them to fit, as needed, and press together in an even layer that covers the bottom completely and goes up the sides.
1 14.1 oz box refrigerated pie crust
Press a layer of foil into/overtop of the crust, then bake at 400° for 10 minutes. Remove the pan from the oven, remove the foil, and set aside.
To a mixing bowl add the pumpkin, sugar, spices, salt, and eggs. Using a hand mixer, blend them all together until evenly combined. Add the milk and blend again, just until evenly combined.
1 15 oz can pumpkin puree, 3/4 cup brown sugar, 1 tsp ground cinnamon, 1 tsp ground ginger, 3/4 tsp ground nutmeg, 1/2 tsp salt, 4 eggs, 1 cup evaporated milk
Pour the batter into the pie crust and spread out in an even layer.
Carefully place the pan in the oven, making sure to keep it flat the whole time since it will be full, and bake at 400° for 30-35 minutes- just until the pie's set.
Remove the pie from the oven and let it rest until completely cooled.
Cover with plastic wrap and refrigerate until cold.
Slice into squares, serve with whipped cream (if desired), and enjoy!
