You don't need baking powder to make a cake, but you need to rely on the sent eggs to foam it.

The method of sending eggs is as follows:

1. separation of egg yolk and egg white (egg white must not be mixed with egg yolk)

2. Add a little salt and a spoonful of sugar to the egg white, and continue beating in the same direction with an eggbeater.

3. Add a spoonful of sugar when you hit this state and continue to beat until creamy.

4. Until the eggbeater or chopsticks can stand up in the bowl, the inverted protein in the container will not fall off.

5. Send the egg yolk in the same way.
