Tips:
Two words
1. Everyone's oven temperature is different, so temperature and time are reference values. As long as the surface of the egg yolk cake turns golden yellow, it can be baked, don't bake it.
2. You can also eat this egg yolk cake without filling, and then squeeze it to be smaller, the taste is very similar to the egg cake we bought in the supermarket. If the squeeze is too small, the baking time should be shortened to avoid mushy.
3. Using yak milk to make the custard sauce is very rich, in order to highlight the milk flavor, I did not add vanilla extract and butter. If the custard sauce is not used up, it can be stored in the refrigerator, but it is best to use it up the same day. This filling can also be used for filling with bread and puffs.
