Make a white cup cake, as just directed, bake in layers and when cold put together with this filling:

Beat stiff the whites of two eggs, whip in a cupful of powdered sugar, then the juice of half a lemon, and the same quantity of orange-juice, in which has been steeped for half an hour and then strained out the grated peel of an orange. Reserve a little and whip in more powdered sugar to make frosting for the uppermost layer.

The effect of the white and yellow is pleasing.

Orange Layer Cake

Four eggs; three cupfuls of flour; two cupfuls of sugar; half cupful of butter; two small oranges ; one cupful of cold water; two teaspoonfuls of Cleveland's Baking Powder.

Add the beaten yolks of the eggs to the creamed butter and sugar, stir in the orange-juice and grated peel, the water, flour, baking powder, and the whites of the eggs last. Bake in layers, and spread between these a filling made by beating into the whites of two eggs enough powdered sugar to make a tolerably stiff frosting, and flavoring this with lemon-juice and grated peel. Add a little more sugar for the top icing than for the layer filling.
