Ingredients
For the Dough
2½cups300g all-purpose flour (or bao flour if available)
2tablespoonssugar
1teaspooninstant yeast
½teaspoonbaking powder
¾cup180ml warm milk (110°F or 43°C)
2tablespoonsvegetable oil
¼teaspoonsalt
For the Red Bean Filling (Optional)
1½cupssweet red bean pastehomemade or store-bought
Instructions
Step 1: Activate the Yeast
In a bowl, combine warm milk and sugar. Sprinkle the yeast over the top, stir gently, and let sit for 5-10 minutes until frothy. This ensures your yeast is alive and ready to give your dough that signature steam bun rise.
Step 2: Make the Dough
In a large bowl (or stand mixer bowl), mix the flour, baking powder, and salt. Pour in the activated yeast mixture and vegetable oil. Mix until a shaggy dough forms. Knead by hand for 10-12 minutes or with a mixer on medium speed for 6-8 minutes. The dough should be smooth, soft, and just slightly tacky.
Step 3: First Proof
Form the dough into a ball and place it in a lightly greased bowl. Cover with a damp towel or plastic wrap and let it rise in a warm spot for about 1 hour, or until doubled in size.
Step 4: Divide and Shape
Punch down the dough and transfer it to a clean surface. Divide into 10 equal portions. Roll each piece into a ball, cover, and let rest for 5 minutes (this helps the dough relax for easier shaping).
Step 5: Add the Red Bean Filling
Flatten each dough ball into a circle about 4 inches in diameter. Place 1-2 tablespoons of red bean paste in the center. Carefully gather the edges and pinch the top to seal. Flip the bun seam-side down and shape gently into a round bun.
For a more advanced twist, you can pleat the dough edges like a steamed pork buns style, giving a beautiful finish similar to traditional chinese bread.
Step 6: Second Proof
Place the buns on parchment squares inside your steamer basket. Leave space between each bun. Cover and let proof for 30 minutes.
Step 7: Steam the Buns
Fill your steamer base with water and bring it to a boil. Once boiling, place the steamer basket over the water and steam the buns on medium-high heat for 12-15 minutes. Turn off the heat and let the buns rest, covered, for 5 minutes before opening the lid to avoid shrinkage.
Step 8: Serve Warm
These buns are best served warm. The dough is lightly sweet, the red bean filling is smooth and nutty, and the texture is dreamy.
