This is a more fudge-y version of a chocolate pie! It has been passed down in my family forever and I have no idea where it came from. Even those who do not like chocolate pie, love this pie. It is foolproof and was the very first thing I ever baked. Always requested on family birthdays and holidays! I serve it with a generous dollop of fresh whipped cream! Also, sometimes I use a pre-made pie crust and sometimes I make my own! NOTE: Yes, this has a lot of calories and fat, you can use margarine instead of butter. Other than that, I would not mess with it too much! I tried it using Splenda and it was less than desirable. UPDATE: 09/16/2009 Per review: I NEVER prebake my pie-crust and it comes out perfectly -- neither have the generations of women who have made this before me. That might be a personal preference, but the recipe is intended to be made with an unbaked pie shell.
