Roll out the pie crust on a floured surface and use a round cookie cutter or a cup to cut out small circles. Aim for a diameter of about 4 inches to fit into a muffin tin.
Gently press each pie crust circle into the muffin tin cups, creating small pie shells. Prick the bottoms with a fork to prevent bubbling.
In a mixing bowl, combine the pumpkin puree, evaporated milk, brown sugar, granulated sugar, egg, pumpkin pie spice, vanilla extract, and salt. Mix until smooth and well combined.
Pour the pumpkin filling into each pie crust, filling them about 3/4 full.
Bake the mini pumpkin pies in the preheated oven for 15-20 minutes, or until the filling is set and a toothpick inserted comes out clean.
Remove the muffin tin from the oven and let the mini pies cool for about 10 minutes before removing them gently from the muffin tin.
Serve warm or at room temperature with a dollop of whipped cream on top and a sprinkle of cinnamon for garnish.
Notes
