The following recipe was used for my Steam Buns cooking class. You can read about my class and get other links to recipes HERE.

2 tablespoons sugar
1/2 teaspoon salt
3 teaspoons baking powder
2 tablespoons canola or vegetable oil
1/3 cup whole milk
1/2 cup cold water

In a stand mixer, fitted with the dough hook, combine the flour, sugar, salt & baking powder until fully combined.
Slowly add the remaining ingredients and allow the dough hook to bring the dough together.
Allow the dough hook to knead the dough for 1-3 minutes until the dough pulls away from the sides of the bowl.
In a large bowl, sprayed with cooking spray (to prevent sticking), place the dough and cover with a damp cloth.
Allow dough to sit for 1 hour before using.
