Prepare the pie crust according to the directions on the box and line it in a
9-inch pie plate. Using a fork, press the dough around the edge of the plate. Line
the pie with aluminum foil and fill with dried beans, uncooked rice or pie weights
so the crust holds shape while baking.
Pre-bake the shell for 10 minutes. Remove
the dried beans, uncooked rice or pie weights and the aluminum foil from the pie
crust and turn the oven down to 325 degrees F.
Meanwhile, in a medium bowl, blend the Nutella with 1/2 cup sweetened condensed
milk and 2 egg yolks, stirring until mixed thoroughly. Carefully spread mixture
evenly into the pie crust and bake for 30 minutes until puffy and just set.
In a second medium bowl, stir together the remaining sweetened condensed milk,
2 whole eggs, canned pumpkin and pumpkin pie spice.
Gently spoon the mixture of
the baked brownie layer of the pie and continue to bake for an additional 25 to
30 minutes or until a knife inserted in the center comes out clean.
