Mix two packages instant vanilla pudding mix with a cup of milk, refrigerate until partly set. Stir in a can of condensed milk, 8 oz. each of sour cream and whipped topping, 3 ripe (freckled) bananas, sliced or diced, a drained 8 oz. can crushed or chunk pineapple. Mix very well, and refrigerate. Layer a casserole with vanilla wafers and pudding—wafers first, pudding last. Top with whipped cream, and sprinkle with wafer crumbs. Some people will sprinkle coconut between the layers and with the topping. Chill very well before serving.
