Molasses Cake Lightly spiced and not too rich, this recipe can be put together very rapidly—and left to bake while first courses are served. Serve hot from the oven, with a pitcher of heavy plain cream or a spoonful of vanilla ice cream. 2 T butter 1/2 cup brown sugar 1 egg 1/2 cup molasses 1/2 cup sour cream 1 T cinnamon 1 tsp baking soda dissolved in a tablespoon of warm water   1 scant cup of flour Cream butter and sugar together, add beaten egg. Combine baking soda mixture with molasses (never add soda directly to sour cream!).  Add molasses to butter-sugar-egg and blend; add cinnamon, sour cream, and finally the sifted flour, mixing thoroughly but not beating too hard. Pour into a greased 6" square pan and bake in a medium (375) oven for 20 minutes.
