Recipe cards were given to customers and this is how it reads:

1/2 package Nabisco chocolate wafers
1/2 cube butter, melted
1 gallon coffee ice cream
1 1/2 cup fudge sauce

Crush wafers and add butter, mix well. Press into 9-inch pie plate. Cover with soft coffee ice cream. Put into freezer until ice cream is firm. Top with cold fudge sauce (it helps to place in freezer for a time to make spreading easier). Store in freezer approximately 10 hours.

Presentation: Slice mud pie into eight portions and serve on a chilled dessert plate with a chilled fork. Top with whipped cream and slivered almonds.
