We lived in Des Moines from 1974-76 and discovered Bishop's Cafeteria at Merle Hay Mall. Anytime we had out-of-town guests, they always wanted to dine there. And of course, everybody had to have a slice of Bishop's Chocolate Pie for dessert. This is a copycat recipe that my mother-in-law gave me many, many years ago. I'm making 4 pies today -- one to keep and 3 to send to Ronald McDonald House tomorrow for a supper that my sorority chapter is serving. There are many variations of this receipe, and this is the one from the kitchen of Helen Julis Court, Ottumwa IA.
