Preheat oven to 350 degrees.
Grease a 7 x 10-inch pan heavily with the melted butter. Distribute cubed bread into the pan, and set aside.
In a medium-sized mixing bowl, combine the remaining ingredients stirring in the milk last.
Pour pumpkin mixture over the cubed bread and allow the bread to soak up the milk mixture for about 10 minutes while the oven preheats.
Bake until a little puffy in the middle and golden brown around the edges, about 55 minutes.
Cool for 20 minutes.
