Place in the oven and bake the 6" cake for 25 minutes, the 9" cake for 30 minutes and the 11" cake for 40 minutes.
When cakes are cooked they should be pale golden in colour. When baked, remove from the oven and leave to cool in the tin and then transfer to a wire cooling rack. Wrap in cling film to keep for up to a day in a cool dry place. If you want to make the cakes in advance – wrap and freeze.
