Chocolate Roll Recipe 1916.
Half a cupful of flour, half a cupful of granulated sugar, two eggs, a little baking-powder, and a small bar of plain chocolate. Whisk eggs well, and gradually add sugar and flour whilst still beating them. Grate the chocolate, and mix to a paste with a little water, then add it to the mixture. Pour into a shallow, buttered tin, and bake for fifteen to twenty minutes. Turn it quickly onto a board dusted with castor sugar, and spread the filling on immediately, and roll up while still warm. The filling can be made of cream and icing-sugar whipped till stiff, or of butter and icing sugar beaten together to a cream.
