Chinese Steamed Buns

I decided to try to make these steamed buns from a Dimsum cookbook by Vicki Liley after eating amazing buns from China. They turned out pretty well and tasted a lot like what I ate in China. I was suprised by how simple the recipe was. All I needed to use was flour, a little sugar, baking powder, milk, oil and water. I put green onions inside the buns. I was originally going to put red bean paste into the buns, but the grocery store ran out. Some of the recipes that I saw online, involved six hour processes that used yeast instead of baking powder.
