Cream together: 1 cup of sugar. 1/2 cup lard and butter, mixed. Yolk of 2 eggs. 1/2 cup pulverized cocoa. 1/2 cup of creamed mashed potatoes, cold. A little ground cinnamon and grated nutmeg. A few drops of essence of vanilla. 1/4 cup of sweet milk. 1/2 cup finely chopped nut meats. One teaspoonful of baking powder sifted with one cup of flour added to the batter alternately with the stiffly beaten whites of eggs. Bake in two layers, in a moderately hot oven. Ice top and put layers together with white icing. This is a delicious, if rather unusual cake.
