My grandma didn't measure anything so this is as close as I could get. I never said it was a healthy recipe. It can be made without the evaporated milk and using low fat or skim milk and using margarine instead of butter but please use real vanilla and a good quality cocoa. You might have to adjust the cornstarch or cocoa depending on how thick or chocolaty you like your pies. I make 2 of these pies for every church covered dish meal and never get to bring a slice home. Oh yes...you can cook the filling in a large double boiler to avoid scorching it, it just takes longer.
