Whether chocolate, lemon drizzle or the classic Victoria, there's a cake for everyone, and it's usually a variation on the wonderfully versatile sponge. Sponge cakes can be made using the creaming method, the whisking method or by adding the cake ingredients to the batter in stages. Flour, eggs, fat and sugar are combined and baked to form a light, porous cake, often with two layers separated by a sweet filling.
