Tips:
1. The butter should be fully softened, the softened butter feels like a paste, so that the sugar can be added;
2. The egg liquid must not be added at one time, it is best to add it in several times, and each time it needs to be fully whipped and then added for the second time to ensure that the butter and eggs are fully emulsified, and there will be no separation of water and oil.
