- Put milk, sugar, yeast in a mixer and mix a little bit then wait for 5 minutes. After that, add salt and flour slowly into the mixer. Let the mixer run for 5-10 minutes.
- Take the dough out and cover the dough with a wet cloth. Let it rise around 30-45 minutes at room temperature. My trick to speed up dough rising time is to preheat the oven at 200F then turn off. After that, put the dough in the oven and cover with a wet cloth.
- In a saucepan put milk, butter, egg, sugar, custard powder and cornstarch into a saucepan and mix it well. Then, turn on the fire small to medium and keep stirring until it thickens. Wait until it cools off then roll like a ball.
- In this steamed custard bun recipe, I doubled the filling because I love more custard filling in the buns. Therefore, it yields around 12 smaller or 10 bigger nai wong bao.
- Cut a small piece of parchment paper and place the buns on it to prevent sticking on the bamboo basket and steam it.
FAQs:
Yes, you can refrigerate or freeze custard buns. Nai wong bao (奶皇包) can be refrigerated for few days. It will last longer when you freeze them.
If it straightens out from the refrigerator, the fastest way to warm up leftover custard buns is to microwave them for a few seconds.
On the other hand, if buns are frozen, cover them with a wet paper towel. Then, microwave it for a minute or two depending on your microwave's power.
However, personally I still like custard buns fresh and steamed from a bamboo basket. Normally, I will steam the frozen nau wong bao (奶皇包) for 5-8 minutes.
When you microwave nai wong bao (奶皇包), the best is to cover it with a wet paper towel. Or, steam them in a bamboo basket.

Does the recipe change if I use instant yeast? Should I still add milk to the yeast?
Tracy O.
Instant yeast does not require blooming which means to add and mix into the ingredients directly. However, you can still add the yeast to the milk.
Caroline
Hi! I don’t have a bamboo steamer so Is it possible to use a metal one?

Yes, a metal steamer is ok too.
Alissa
Hi! Do you think I could use the custard filling for the baked pineapple bun version or would this only worked for steamed buns? Thanks!
Tracy O.
Hi Alissa,
I think this custard filling should work for baked pineapple buns.

Just finished making these, and they came out amazing! I decided to double the custard as well and am very glad that I did - it is so tender and delicious! 🥹
Will definitely be making these again. Thank you so much for the recipe Tracy!

Is this possible to make without a Bosch mixer?

Yes, sure! You can knead the dough by hand. Using the Bosch mixer or any mixer just help the process faster.
