Old Fashioned Chocolate Icebox Cake
(no need to wash beaters after whipping the whites), beating at high speed, until mixture is light and fluffy. Fold the egg whites into the chocolate mixture. Turn half the mixture into the pan lines with ladyfingers. Top with another layer of ladyfingers. Cover with remaining chocolate mixture and still another layer of ladyfingers. Cover and chill 24 hours, until set. Unmold onto serving platter and decorate with whipped cream.
This recipe was specially prepared for the owners of the new General Electric refrigerators in 1927.
