Peter Pan Cake

==Description==
This cake is a long time favorite with a delicious flavour while baking. They taste great with a glass of cold skim milk. The original recipe is rumored to descend from the early 1900s, from John Pan. There is no real explanation why the cake has later been called Peter Pan.
