Chinese Sponge Cake Baked Not Steamed

My mom used to make this cake when we we were growing up. I love it because it's light and fluffy. please note, use an aluminum cake pan for this recipe (we've always used an aluminum angel food cake pan). do not use a non-stick pan! i am on a quest to find the recipe for the chinese bakery cakes. i'm not talking about those chinese steamed sponge cakes. i'm in search of the fluffy ones that come with the fruit and whipped creamy frosting. if anyone knows this recipe, please forward to me--i will be forever grateful! in the meantime, this cake is the closest thing to it.
