Sponge cake is a light cake made with eggs, flour and sugar, sometimes leavened with baking powder. Sponge cakes, leavened with beaten eggs, originated during the Renaissance, possibly in Spain. The sponge cake is thought to be one of the first of the non-yeasted cakes, and the earliest attested sponge cake recipe in English is found in a book by the English poet Gervase Markham, The English Huswife, Containing the Inward and Outward Virtues Which Ought to Be in a Complete Woman (1615). Still, the cake was much more like a cookie: thin and crispy. Sponge cakes became the cake recognized today when bakers started using beaten eggs as a rising agent in the mid-18th century. The Victorian creation of baking powder by English food manufacturer Alfred Bird in 1843 enabled the sponge to rise higher than cakes made previously, resulting in the Victoria Sponge.
