Sweet, chewy, doughnut balls filled with sweet red beans

Chapssal doughnuts 찹쌀도너츠

Today’s recipe is one of the most popular Korean snacks, chapssal doughnuts. They’re a modern Korean treat combining traditional Korean rice cakes with Western style deep fried doughnut balls. On the outside the dough is crispy and chewy, and on the inside there’s soft, lightly sweet red bean paste.

You can find them in many Korean bakeries among the other sweet and savory treats. They’re not hard to make, but the red bean filling takes time and effort to get right. I did many experiments to come up with the best method to make the most delicious and less sweet chapssal doughnuts that have the best chewy-crispy texture. They’re really unique!

Enjoy the recipe and let me know if you try it!

Ingredients

For the dough:

For sweet red bean paste (about 1 pound):

For frying and coating:

  • vegetable oil
  • 2 tablespoons of white sugar

Directions

Make the dough:

  1. Combine glutinous rice flour, flour, kosher salt, baking soda, and melted butter in a large bowl. Add hot water and mix with a wooden spoon for 1 minute.
  2. Form it into a lump as it gathers together.kneading dough
  3. Knead the lump by hand for 2 minutes, until smooth. Put it in a plastic bag to keep it from drying out.

Make the sweet red bean paste:

  1. Wash the azuki beans in cold water and strain. Put them into a solid, heavy-bottomed pot.
  2. Add 7 cups of water. Cover and boil for 30 minutes over medium high heat.
  3. Turn off the heat and let the beans soak in the hot water for 30 minutes.
  4. Turn on the heat to medium and cook for 1 hour until the beans are very soft.
  5. Remove from the heat and mash the beans with a wooden spoon or potato masher.mashing red beans
  6. Add 3 cups of water and stir into a watery paste.
  7. Set a strong mesh strainer over a large bowl and strain the paste through it to remove the bean skins.
  8. Use your hands to squeeze every drop out of the skins as best you can. Discard the empty skins and wash the strainer to use it again.
  9. Put the strainer over an empty bowl and line it with a clean cotton cloth. Strain the paste by pouring it through the cloth and strainer.
  10. Lift up the edges of the cloth and gently squeeze it to force the all water through.
  11. When all the water has passed, you’ll be left with a solid lump of finely ground, cooked beans inside the cloth.
  12. Put it into the pot, and turn the on heat to medium high. Add sugar, rice syrup, kosher salt, and vanilla extract.
  13. Stir well with a wooden spoon for about 6 to 7 minutes until the bean paste moves together as a lump. Remove from the heat and let cool.red beans
  14. Use about 200 grams (7 ounces) of the red bean paste for this recipe and freeze rest for another day.

Shape the doughnut balls:

  1. Divide the paste into 10 pieces and roll each piece into a smooth ball. Cover with plastic wrap so they don’t dry out while you work.red bean balls
  2. Divide the dough into 10 pieces (each one about 1 ounce, or 28 grams) and roll each piece into a smooth ball. Cover with plastic wrap.
  3. Put one of the dough balls on the cutting board and flatten it out with your hand into a disk about 2½ inches in diameter. Make a circle with your thumb and forefinger and put the disk on top of it.
  4. With your other hand put one red bean paste ball in the center of the disk and push and pull the dough around it, so the red bean ball is completely covered by the dough.
  5. Seal the dough gently and tightly around the red bean, and softly roll the ball on your cutting board to smooth out any lumps. Repeat this with the rest of the dough and red beans to make 10 balls.

Fry the doughnuts:
I usually use my 7 inch stainless steel sauce pan with 3 cups of oil and fry 5 balls at a time to save on oil, but you can use more oil and fry them all at once in a larger pan if you want.

  1. Heat up vegetable oil in a deep pan to 300°F (150°C).
  2. Fry the balls for 6 to 7 minutes over medium low heat, until light golden brown. As they fry, stir gently with a wooden spoon so they’re cooked evenly and don’t stick to the bottom of the pot.
  3. Strain and let them cool for 1 minute.

Serve:

  1. Roll in sugar to coat, and serve. Finish in several hours, for the best chewiness!

    Hi Maangchi!
    I just wanted to say I am obsessed with your videos!
    And these chapssal doughnuts!!!
    I came across your recipe because my mum who lives in Czech Republic said she wants them but she couldn’t find them anywhere :(
    So I wanted to practice making it for when she next visits me in UK
    Your chapssal doughnut recipe is so good I have already made it twice in the past week!
    And I want to make them again this weekend for a friend’s birthday party, but I was wondering is it possible to make the dough in advance night before? Just so it saves me some time on the day of the party! I have already made the redbean paste and froze it :)
    Thank you!

    Hello Maangchi ! I want to make these beautiful chapssal doughnuts and I was wondering if freezing them before frying would be okay or not ? I would like to make a batch in one go and keep some in store in the freezer so I could eat these delicious balls whenever I feel like it ㅋㅋㅋ

    Hello, I have made this twice already, your recipe is very good. Do you have suggestions on how I can make the donut hollow since sometime I just want to eat the outside without the beans?

      Hi Jack,

      I just made this recipe, stuffing it with 1-2 walnut halves with/without sugar and or nutella. And it does puff up pretty well as opposed to the non-stuffed version. I think you can stuff it with anything and it will puff. There needs to be something in there to create a stable pocket for air.

    Hello~ I tried out the recipe and while it was frying they started to explode. Do you know why that is?

    I love everything about what you do, this is truly amazing. This is so crazy, i remember watching your videos back then when i was just a kid, maybe 15yrs old or so, and i became immediatly a big fan :) haha i remember begging my parents to make the tea « sew jung gwa » or something, with the dried persimmons. It never happened though, mostly because those persimmons were not available in our area. But here i am, 25, making these doughnuts, which is officially my first ever attempt at Korean Cuisine. Turned out great! Can’t wait to try more!

      At the age of 15 you couldn’t make it, but you were so interested in Korean good, you even asked your mom to make it for you. So definitely you will be good at Korean cooking, because you were so interested in food and now you are ready to cook. Happy cooking!

    Dear Maangchi-ssi!
    Me and my eldest daughter prepared the paste and the doughnuts a few days ago – so delicious and beautiful!!! My whole family loved it and today I had to cook red bean paste again… :)
    May I ask why you changed your recipe for the red bean paste from adding three cups of water to seven cups and from keeping the skins to discarding it? I tried out both recipes and for me the first one (with skins) tasted somehow better although I understand that for making patisserie the very smooth paste without skins should be first choice.
    Anyway – here is a photograph of our team work… Many, many admiring greetings from Germany.

      Hi Sugarprincess!
      I love the photo! You worked so hard to describe what you did in one photo! : ) The doughnuts look very pretty and well made.
      Regarding your question about the red bean paste, I prefer the soft and smooth texture of the sweet red bean paste rather than a little rough and coarse paste. It’s up to your decision which way you would want it to taste like.

    Hello Maangchi – is it possible to buy red bean paste and make these? I plan to make it with a friend but we don’t have so much time :( Thank you!

    The whole family is enjoying your wonderful videos along with my attempts at some of your recipes. You are so instructive and I really appreciate that you show your method several times in a video to give us the chance to really absorb it.

    PS. I hope your Tee is JUST a shirt, and you are not wearing it because trolls have found you. You are wonderful.

    Hi, Maangchi! I can’t eat gluten, and these are *so* close to being gluten-free. Do you know if I could make them using another flour instead of the 1 Tbsp. of wheat flour? Thanks in case!

    Maangchi – I was wondering if in Korea people eat Steamed Red Bean Buns. I know that there is a Chinese steamed bean bun, and also that the Steamed Pork bun is also eaten in China – so I wasn’t sure if Red Bean Buns are also eaten in Korea like Steamed Pork Buns are in China. I hope my wording isn’t too confusing lol
