If the egg white doesn't foam, you can use a rubber scraper to evenly stir the egg white up and down, and then cut and scrape it without circling. Too little flour will shrink. You'd better have a measuring spoon. The cake shrinks easily when it is not ripe. When it's ready, take it out and turn it around. Removing the cover of the rice cooker before the cake is fully cooked will lead to steam reflux. Cake shrinks when it loses moisture. So be careful not to open the lid until the cake is cooked. The batter was poured into the rice cooker without being stirred evenly.
Because when the pot is opened, cold air comes in and condenses into water droplets, and the cake collapses. The cake should be taken out immediately with the liner and cooled upside down. There is also a little baking powder when making cakes. Generally speaking, a cake with a larger proportion will sink to the bottom, and a cake with a smaller proportion will float, so that the cake will easily shrink. During the heating process, it is best not to open the lid when it is not ripe, or the cake will shrink back. If it is not inverted immediately after baking, the temperature at the top and inside of the cake will drop sharply and shrink. So, don't wait too long to take it out. Turn it upside down immediately and wait until it is a little cooler.
