Cream the butter and sugar together as usual, and then break in three eggs and beat until very creamy. Add the flour and milk alternately, reserving a little of the flour to add after the vanilla and baking-powder. Beat well and bake in layer cake tins. The entire success and lightness of this cake depends upon the beating of the sugar, butter and eggs. If these are beaten long enough they will become as creamy and fluffy as whipped cream.
Moisten to make the mixture the consistence of very thick cream. Cream or whipped cream may be used for the mixing, but many like this icing when made with lukewarm coffee. The sugar and butter are creamed together thoroughly and then the cocoa and vanilla are added, and lastly the cream or coffee. This is a good imitation of German tree cake. The icing on tree cake is an inch thick, and it is marked to represent the bark of a tree. The way it is served is with a little green candy on it, and it is really very delicious although extremely rich. The thicker or rather firmer this icing is, the better.
