Sponge Cake

Sponge cake is a light, airy dessert made primarily from eggs, sugar, flour, and a small amount of fat. The key to its texture is carefully whipped eggs or egg whites, which incorporate air and create a fluffy batter. When baked, this trapped air expands, giving the cake its soft, moist crumb. Unlike butter or pound cakes, sponge cake relies on the whipped eggs for structure and leavening rather than added fats or chemical leaveners. Its delicate texture makes it a popular base for layered cakes, often paired with whipped cream or fruit fillings.
