Sponge fingers, also known as Savoiardo in Italian, are light and airy sponge cakes that are shaped like elongated fingers. These delicate treats are typically made with a simple batter of eggs, sugar, flour, and sometimes a touch of vanilla extract. Sponge fingers have a soft and spongy texture, making them perfect for soaking up flavors in desserts like tiramisu or trifle. They are often used as a base or layer in various desserts, adding a light and fluffy element to the overall dish. Sponge fingers are versatile and can be enjoyed on their own or as part of a delicious dessert creation.
