Original recipe
Molasses Cake. - Cut up a quater of a pound of fresh butter unto a pint of West India Molasses. Warm it just sufficiently to soften the butter, and make it mix easily. Stir it well into the molasses and add a tablespoon of powdered cinnamon. Beat three eggs very light and stir them, gradulally into the mixtire, in turn with barely enough of sifted flour (not mroe than a pint and a half) to make it about as thick as a pound-cake batter. Add, at the last, a small or level tea-spoonful of pearlash, or a full one of soda, dissolved in a very little warm water. Butter some small tin cake-pans, or patty-pans, put in the mixture, and set them immediatly into the oven, which must not be toohot, as all cakes made with molasses are peculiarly liable to scorch on the outside.
