1. Beat two eggs into a bowl, not egg whites, but egg yolks, then mash the egg yolks with chopsticks and stir them into a thin state.

2. Pour the milk into the pot and heat it until the milk bubbles.

3. Put the chocolate and thin egg yolk into the pot and heat them together until the chocolate melts into chocolate milk.

3. Pour the chocolate milk into a small bowl, cool it, and then put it in the refrigerator for several hours to eat.

Precautions:

1. The amount of eggs can be increased appropriately, but too much will smell fishy.

2. If the yolk is difficult to get out, you can scoop it into another small bowl with a small spoon.

Remember to stir the egg yolk evenly, or the egg yolk will turn into an egg roll when heated.

4. After the milk bubbles, add chocolate and thin egg yolk.

You don't need frozen chocolate milk to eat chocolate milkshake. But remember to cool it. It was very hot just after the heating was turned on.
