There’s something deeply comforting about steamed buns—the kind that come out warm and soft from a bamboo basket, releasing a gentle puff of steam as you lift the lid. Now imagine one filled with molten chocolate. These Chocolate Steamed Buns are a fusion of East and West, bringing together the time-honored tradition of Asian bao and the universally adored decadence of chocolate. The result is a soft, slightly sweet dough surrounding a rich, velvety ganache center that oozes out with every bite.
Growing up, bao was a staple in my family. We would enjoy them during weekend dim sum outings, usually stuffed with char siu or sweet lotus paste. But the first time I bit into a chocolate-filled steamed bun, it was a revelation—modern, unexpected, and absolutely delightful. It felt like childhood and luxury combined into one. Since then, these buns have become a beloved part of my recipe collection, reserved for special breakfasts, cozy rainy days, and heartwarming dessert tables.
These chocolate bao buns have a gentle sweetness, a light texture thanks to wheat starch, and an indulgent chocolate core that makes each one feel like a gift. Perfect for Lunar New Year with a twist, Valentine’s Day surprises, or holiday brunches, they’re a treat that feels both nostalgic and new.

INGREDIENTS YOU’LL NEED:
For the Dough
- ¾ cup (180 ml) whole milk, warmed to 110°F (43°C)
- 1½ tsp (6 g) active dry yeast or instant yeast
- 2 cups (300 g) all-purpose flour
- ¾ cup (100 g) wheat starch
- ½ cup (70 g) powdered sugar
- 2 tsp (10 g) baking powder
- ¼ tsp salt
- 1 tbsp (15 g) vegetable shortening
- 1 large egg white
- 1 tbsp (15 g) vegetable oil

For the Chocolate Ganache
- 1⅓ cups (8 oz) semi-sweet chocolate chips or melting wafers
- 1 cup heavy cream
How to Make Chocolate Steamed Buns
Prepare the Ganache
Start by making the filling—it needs time to chill and firm up. Heat the heavy cream in a small saucepan until it just begins to simmer. Do not let it boil. Pour the hot cream over the chocolate chips in a heatproof bowl. Let it sit for 10 minutes, then stir until smooth and glossy. Refrigerate uncovered for 30 minutes, then cover with plastic wrap (press it directly on the surface of the ganache to avoid skin forming) and chill another hour or until firm.
Make the Dough
Warm your milk to 110°F and stir in the yeast. Let it sit for 10 minutes until foamy—this blooming process ensures the yeast is active. In a stand mixer fitted with the dough hook, sift together the flour, wheat starch, powdered sugar, baking powder, and salt. Add the vegetable shortening and briefly mix on low. In a small bowl, whisk together the egg white and oil. Add this mixture to the dry ingredients along with the yeast-milk mixture.

Knead the dough on medium speed until it becomes smooth and elastic—about 5 minutes. If the dough feels too sticky, add flour 1 tablespoon at a time. If it feels dry or crumbly, add a splash of warm water. Once it pulls away from the sides of the bowl, shape it into a ball and let it rise in a greased bowl covered with a clean towel in a warm spot for 1 to 2 hours, or until doubled in size.
Shape the Buns
Once the dough is ready, punch it down and turn it onto a floured surface. Divide into 12 equal pieces. Flatten each into a round disc, keeping the center slightly thicker. Scoop about 1 tablespoon of the chilled ganache into the center. Fold the edges over and pinch to seal well. Place each bun seam-side down on a square of parchment paper.
Let the buns rest, covered, for 15 minutes while you set up your steamer.
Steam the Buns
Bring your steamer water to a gentle simmer over medium heat. Wrap the steamer lid with a towel (secured tightly so it doesn’t droop) to prevent condensation from dripping onto your buns. Steam the buns in batches for 10 to 12 minutes. Let them sit in the steamer with the heat off for 1 minute before removing the lid—this helps prevent wrinkling.
Helpful Tips
- Use wheat starch for that ultra-smooth, soft dough texture—it makes a difference.
- Don’t skip the lid towel: it protects your buns from getting soggy tops.
- Freeze ganache portions if you want to fill buns quicker next time.
- Seal well when forming the buns to avoid any chocolate leakage.
- Steam in batches so buns don’t crowd or touch during cooking.
