Milk tea cocoa steamed buns roll

Since I started making pasta, steamed buns have always been my specialty.
Since I have been successful in making steamed buns (of course, I am not as good as Lao Yang, who has been successful as soon as I start making steamed buns), my mother has liked to eat my steamed buns. She said that the steamed buns I made had a fragrant aroma and chewy taste. She likes the feeling of chewing and thinks that the steamed buns bought outside are fluffy and not delicious. Once she summarized my three major strengths, one of which was making steamed buns! Hehe! Tomorrow is Mother's Day, and I don't know what to give my mother. Originally, I wanted to go to the wholesale market to buy some pizza boxes and make a big pizza for my mother, but it didn't go as expected and it rained. The wholesale market is very far away from where I live, probably across the entire Nanchang City. So use this as a backup first, and if the weather is fine in the afternoon, go buy a pizza box.
Cocoa powder is a very commonly used food in western cakes. I believe many bakers have this powder. However, they can't just buy a little bit every time they buy it, so there will be a lot more. I think all things are alive and we can't waste them. This seems to have nothing to do with having money or not. My principle is to make the best use of everything as possible.
I bought this cocoa powder at Metro, which belongs to a mass-selling supermarket. I often buy everything that is not available in ordinary supermarkets. However, the disadvantage is that you can't buy the same individually. You're always forced to buy double copies. This cocoa powder is sold together, and you don't need so much for baking. In addition, you can't finish the 2 packs of milk tea powder given by my colleagues, so I just wanted to use it to make steamed buns. I didn't expect that the steamed buns would both sell like and taste very good.
