i agree... wasc all the way. and there are sooo many variations on it, too!

With any cake recipe I do the following - it wokrs every time! - Take the cake from the oven, let cool 5 - 10 minutes, then remove from pan and immediately wrap warm cake in saran wrap (cling wrap) Let it cool on a rack in these wrappings. The steam will stay trapped in the cake and create natural moisture. I read this in a Scott Wooly Clarke book and tried it once and have used it almost every time in the past few years since I read that!

I prefer the original Recipe. It's great and most of all, easy.

Thanks for all your input. Chanielisalevy is frosting difficult when steamed?
