Half a cupful of butter, two and a half of sugar, one of milk, three and a half of pastry flour, three eggs, one teaspoonful of cream of tartar, half a teaspoonful of soda, flavor to taste. Beat the butter to a cream, then beat in the sugar, next the eggs, well beaten; the seasoning, the milk, and lastly the flour, in which the soda and cream of tartar have been thoroughly mixed. Bake in a moderate oven, either in loaves or sheets. If in sheets, twenty-five minutes; if in loaves, forty-five. The quantities given are for two loaves or sheets. This cake is nice for Washington or
chocolate pies, and is good baked in sheets and frosted.
