2 ounces of chocolate,
4 eggs,
1/2 a cup of milk,
1 teaspoonful of vanilla,
1/2 a cup of butter,
1-1/2 cups of sugar,
1 heaping teaspoonful of baking powder,
1-3/4 cups of flour.
Dissolve the chocolate in five tablespoonfuls of boiling water. Beat the
butter to a cream, add the yolks, beat again, then the milk, then the
melted chocolate and flour. Give the whole a vigorous beating. Now beat
the whites of the eggs to a stiff froth, and stir them carefully into
the mixture; add the vanilla and baking powder. Mix quickly and lightly,
turn into well-greased cake pan and bake in a moderate oven forty-five
minutes.--_From Mrs. Rorer's Cook Book._
