Recipe For Cooking Devils Food Cake
From Practical Cooking And Serving by Janet McKenzie Hill, 1919. Section 535 of 825.

1/2 cup of butter. 2 1/3 cups of flour. 2 cups of sugar. 1/2 teaspoonful of cinnamon. 4 eggs. 4 teaspoonfuls of baking-powder. 1 cup of milk. 1 teaspoonful of vanilla extract. 1/2 cup of grated chocolate (2 oz.).
Cream the butter with one cup of the sugar; add the other cup of sugar to the beaten yolks and combine the two; add the milk alternately with the flour, sifted with the cinnamon and baking-powder, then the vanilla, the whites of the eggs beaten dry, and lastly the melted chocolate. Bake in a tube pan or in layers. Put together and ice with boiled frosting, to which candied fruit, cut fine, has been added; or a marshmallow icing. Or, bake in a sheet, ice with boiled frosting and spread one fourth pound of "Dot" chocolate, melted, over the icing. (See illustration.)
