So I found a post on I think craft gawker, which is weird because that's a crafting site, of a perfect sponge cake! The recipe for the cake and fillings is found on http://lulussweetsecrets.blogspot.com/2012/02/perfect-cake.html?m=1
The cake has a strawberry jam and a sweetened condensed milk layer and the "frosting" is basically a whipped cream. But don't worry, all three are on the blog post from Lulus Sweet Secrets. Also, instead of making 3 different smaller cakes, my boyfriend and I made one cake and just used a leveler to make two layers.
