steamed cake

I remembered that the first time I made cakes at home was when my husband's birthday was in February. In order to surprise him, he spent three hours making a birthday cake. At that time, the cake was made with an electric rice cooker. Later, I did it a few times and found that the bottom layer was always undeveloped. I don't know if it was because the rice cooker only heated at the bottom and was not heated uniformly.
Recently, we have studied steaming cakes, using a steamer to steam cakes. I made two servings. One was made with whole eggs without separating the egg white and egg white; the other was made separately. After it is cooked, the taste is similar, but there is a difference in taste. The whole egg is dry. After eating it, my mother said it looks like a steamed cake, hehe, but the ones cooked separately will be wetter. I think everything is okay. The one I make is better than the one outside, healthy and hygienic!
