Prepare your bamboo steamer baskets with a liner and soak the bottom edge of the lowest steam basket in water for 30 minutes.
Heavily flour your work surface and place 1/3 of the master dough recipe onto the flour.
Press the dough into a disc and add about 1/4 cup of flour along with 1/2 teaspoon baking powder on top.
Knead the dough for about 3-4 minutes to incorporate both the flour and baking powder until the dough is no longer tacky. Add more flour as needed.
Using a rolling pin, roll the dough out until it's 1/4-inch thick.
Using a large biscuit cutter (or a Mason jar ring) cut out your bao buns.
Roll the buns out so they're just a bit larger (if desired).
Brush the bao buns with oil and fold them in half.
Using a rolling pin, gently roll over the bun to seal it.
Gather any remaining dough and repeat steps 4-7 until all buns are formed.
Place bao buns into the prepared steamer baskets, stack and add the lid.
Boil water in a large pan on the stove (I'm using my wood stove) and place the steamer basket in the water.
Be sure the water isn't touching the portion of the basket where the buns are, it should only come up on the “legs” of the basket.
Steam your bao buns for eight minutes and then remove from the heat.
Allow them to cool slightly and enjoy!
