Easy "lime/lemon/peach/coconut/anything really" cake

This is the easiest cake recipe and the best part is not only is it deliciously moreish and moist but you can add just about any flavour you like to it! It is just as lovely with coffee for afternoon tea as it is warm and served with custard for dessert.
