Add all of the ingredients for the crust into a large bowl and stir to combine. The crust should feel like wet sand but hold its shape when pressed. Pour the graham cracker crust into a 9-inch pie dish, and use your fingertips to press the mixture into the dish, including the sides, to form the crust. Set aside.
Whisk the eggs, egg yolk and sugar in a large bowl. Add the spices and pumpkin puree, and whisk to combine. Slowly drizzle in the evaporated milk, whisking until the milk is incorporated evenly.
Pour the filling into the shell. Bake the pie for 1 hour or until the filling is set. Allow it to cool completely. Refrigerate if not serving right away.
When ready to serve, sprinkle the remaining ¼ cup sugar evenly over the pie. Using a kitchen torch, heat the sugar until it is brown and bubbling but not burnt. If the sugar layer seems thin, repeat with more sugar.
Serve immediately with whipped cream or vanilla ice cream. Enjoy!
