This is my mum's chocolate sandwich cake recipe which she used to make for all the birthdays in our house. Now I make it for my family! The secret is to add whisked egg whites so the chocolate sponge cake is light. The chocolate buttercream filling and icing for this cake is easy to make and hides a multitude if your chocolate sponge cake doesn't turn out perfectly!
A really light chocolate sponge cake! Tasted even richer the second day. Will keep this recipe for my next birthday! - 10 Oct 2013
