Ladyfingers, or in British English sponge fingers, are low-density, dry, egg-based, sweet sponge cake biscuits roughly shaped like large fingers. They are a principal ingredient in many dessert recipes, such as trifles and charlottes, and are also used as fruit or chocolate gateau linings, and for the sponge element of tiramisu. They are typically soaked in a sugar syrup or liqueur, or in coffee or espresso for tiramisu. Plain ladyfingers are commonly given to infants, being soft enough for teething mouths, but easy to grasp and firm enough not to fall apart.

Sponge cake is a light cake made with eggs, flour and sugar, sometimes leavened with baking powder. Some sponge cakes do not contain egg yolks, like angel food cake, but most of them do. Sponge cakes, leavened with beaten eggs, originated during the Renaissance, possibly in Spain. The sponge cake is thought to be one of the first 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 cracker: thin and crispy. Sponge cakes became the cake recognised 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 allowed the addition of butter to the traditional sponge recipe, resulting in the creation of the Victoria sponge. Cakes are available in many flavours and have many recipes as well. Sponge cakes have become snack cakes via the Twinkie.
