Fluffy steamed buns filled with sweet red beans

Jjinppang 찐빵

Today’s recipe is for traditional Korean jjinppang: fluffy steamed buns filled with red beans. I shared a similar recipe a long time ago for steamed fluffy buns filled with vegetables and meat called jjinppang-mandu. My jjinppang mandu recipe has been used by many of my readers over years and the video has been popular too, even though it was filmed before I had an HD camera and looks kind of blurry.

Hot and fluffy steamy jjinppang is irresistible! They are soft on the outside with chunky sweet red bean paste in the middle, great for a dessert or snack, or even a light meal.

One key to this recipe is to leave some chunky bits of the red beans and skins in the filling so it has a bit of a rough, homemade texture.

I hope you and your family enjoy this recipe for a long time, just like my jjinppang-mandu recipe!

Ingredients

For sweet red bean filling:

For dough:

  • 2 tablespoons butter
  • 1½ cup whole milk
  • 2 tablespoons white sugar
  • 2 teaspoons dry yeast (1 package)
  • 1 teaspoon salt
  • 3½ cup plus ¼ cup all purpose flour

Directions

Prepare the beans:

  1. Wash and soak the red beans overnight, for at least 10 hours. They will expand to about 2½ cups of beans.
  2. Drain and put the beans into a heavy pot. Add 4 cups of water. Cook for 1 hour over medium heat until the beans are very tender.
  3. Add sugar, rice syrup, salt, and vanilla extract. Roughly mash with a potato masher. Turn up the heat to medium high heat and stir a few minutes until the bean mixture turns thick and juicy. Remove from the heat. Cover and set aside.

Prepare the dough:

  1. Heat the butter in a large heavy pot over medium high heat. Stir with a wooden spoon until well melted. Add sugar and stir well. Remove from the heat.
  2. To cool it down so the yeast can work, add cold milk and mix it well. Then add the yeast and let it sit for 5 to 10 minutes until the yeast gets foamy.
  3. Add the salt and stir it well with a wooden spoon. Add flour and mix well for about a minute.
  4. Knead the dough by hand for a few minutes until smooth. Cover and let it sit on the kitchen counter for 1 hour until the dough doubles in size.
  5. Deflate the dough and knead it again for a few minutes. Cover and let it sit for 30 minutes.

Make and shape the buns:

  1. Before shaping the buns, fill your steamer with about 2½ inches of water and bring to a boil. Remove from the heat. Put the steamer basket next to you, so you can add buns to it as you work. Place a cotton cloth (or “steaming sheet”) in the steamer basket.
  2. Deflate and knead the dough until smooth. Use the remaining ¼ cup flour to dust your cutting board.
  3. Divide the dough into about 10 pieces, with each piece being about 3 ounces. Form into smooth balls and put them on the cutting board. Cover the dough balls with plastic wrap to keep them from drying out while you work.
  4. Flatten each dough ball into a disk about 3½ inches in diameter. The edges should be thinner than the middle because we’re going to gather them together to form a bun and we don’t want that part to be too thick.
  5. Put about 2 ounces of sweet red bean filling into the center of the disk. Lift the edges up around the filling and pinch them together to seal tightly and make a bun.
  6. Put it on the cutting board with the sealed side down. Turn it around and shape it with your hands into a small mountain. Put it on the steamer basket lined with steamer liner or perforated parchment paper.
  7. Make the rest of the buns, spacing them 1 inch apart on the steamer basket so they have room to expand. Let them rise for 30 minutes.

Steam and serve:

  1. Reheat the water in the steamer and put the steamer baskets with the buns inside. Put a large cotton cloth under the lid so that the water doesn’t drip back down onto the buns. Cover and steam over medium hight heat for 12 minutes.
  2. Turn the heat down to low and cook an additional 3 minutes.
  3. Remove from the heat and serve right away.Jjinppang
  4. Freeze (up to one month) or refrigerate (up to one week) any leftovers. When you want one, steam or reheat it in a microwave.

    Hi Maangchi, I tried making this and I cut the recipe in half.
    For some reason, the yeast wasn’t very foamy and I don’t know why. I made pizza dough in the past so I know how yeast foams up… I make sure the temperature is right (around 110 F).

    The final product was delicious but the texture of the bun was not too great. The dough didn’t puff up beautifully like yours!

    Hello Maangchi:

    Just made the buns and they turned out to be exactly like the one you showed us above.

    Excellent, thanks so very much for this healthy dish. I however made it with gluten free flour and increased the quantity of yeast and still they were just as good and delicious.

    THANK-U!!!

    Hi Maangchi,

    Thanks for the steamed bun recipe. I am definitely gonna make it. Would you also put the recipe for veggie steamed buns? I grew up eating them and would love to share them with my husband who is not as familiar with korean food. Thanks so much!

    I succeeded at making the bun part so I want to move onto the filling now! :D
    I soaked my azuki beans in cold water for over 10 hours in the fridge but they still look the same. They’re still rock hard and the same size as before. Can I still start cooking them or should I soak for however long until they become plump like Maangchi’s?

      Hard to tell.
      Taste the water: If it tastes sour – no chance.
      Old beans take longer.
      Anyways: Soak them in a cool place, but not the refrigerator – that’s too cold.
      If it still takes more than a few hours: change the water to prevent it to get sour.
      Adding a pinch of baking soda helps, but may taste funny.

      Or (last resort ;-)) you put them in a pot with water, bring to a boil, turn off the heat, let them stand for ten minutes, boil them until done. This way, they may “explode”, but that doesn’t matter with this recipe. ;-)

      Bye, Sanne.

      Soaking adzuki beans can take a long time, depending on the beans. That’s why I usually boil them over low heat with a lot of water, until they soften. That way, you don’t have to wait so long.

    Is it okay if I store them at room temperature for a few days?

    • sanne Munich joined 8/14 & has 188 comments

      I wouldn’t.
      If you plan to eat them over the next few days: Wrap the steamed buns individually in plastic foil and put them in the fridge or freezer.
      To freshen them up ;-), put one moistened with a little water in a small microwave-proof container with lid (glass or ceramic) and “nuke” it for a few moments (thaw it first if frozen).
      Be very careful when eating it then, the filling will be scalding hot!
      Or steam them again, but that’s only worthwhile if you do that with a batch large enough to fill your steamer, one layer at least.

      If you plan to prepare them beforehand: wrap them up like described before right after having them filled and freeze them. To steam them, just unwrap them, put them in the steamer a few hours before you need them, let them thaw and rise until they are as desired, steam them like freshly made.

      Bye, Sanne.

    Hi Maangchi I love your recipes❤️ Could I use the parchment paper for bamboo steamers? I cannot find the same paper you use in your steamer.
    Thank you

    • usrnmna Los Angeles joined 1/18 & has 3 comments

      Yes, absolutely. I believe, unless they are made of cotton or silicone, the paper ones are all parchment material. They’re widely available on amazon or you can just cut-out a round shape from regular parchment paper. I ordered a steamer pot from amazon just to make this recipe but forgot about ordering the linings, so I’m just going to use the parchment paper I have on hand. Awesome! :)

    I followed the recipe but my dough didn’t turn out sticky. It was stiff. What should I do? What happened?

    I maded them today and I must say that for lunch they are too sweet for me and my wife ;) Maybe I added to much of rice syrup. My buns actually went bigger, they even rise much at steaming process :P But they are really filling stomach very fast, two buns and I’m full. Maybe next time I fill them with kimchi or put some bulgogi inside to make this dish more lunch style.
