I have made one of these before but forgotten how to and i cant find the recipe for i again. It was alot like a simple sponge cake but it had peanut butter in it. would it work if i was just to make a normal victoria sponge (without the jam) and substitute half the butter or 3/4 of the butter with peanut butter??? if you have seen any recipes on the net for a simple peanut butter sponge then could you please send me a link. Any help appreiated. Thanks
