All the sponge cake

Spongecake is a form of protein bubbles that fills the egg fluid with a large amount of air, adding to the kind of condensed snack made of flour. It's famous for its structure similar to a porous sponge. Foreignly, it's called foam cake, and domestically it's called cake cleaning. The production of whole sponge cakes is particularly simple and saves some of the other cakes, and even new players have almost failed. The cake is unbreakable, it prefers the sponge-cake taste, and the baby at home especially likes the smell of a little roast。
