Why do you want to send egg whites when making cakes? Do I need to send egg whites to use self-raising flour? Can you use it instead of microwave cake powder?

The cake is made of egg white because the sponge tissue of the cake is supported by egg white. If the egg whites are beaten well, the cake will become soft. If the cake is made of self-raising flour, it will taste like egg yolk steamed bread. The cake is made of low-gluten flour, sugar, salad oil, eggs and milk. There are many on the internet, and the key is hair protein. Microwave cake powder is a kind of pre-mixed powder, and the cake made is like muffin cake, not very soft.
