Soboro adzuki bread, 소보로팥빵, is a soft bun stuffed with sweetened red/adzuki beans and baked with a peanut streusel on top. It’s a commonly found item in Korean bakeries.
Last year, I wrote about one of Korea’s most popular bread items, the soboro bread, 소보로빵 or peanut streusel bread. Today I want to introduce you to its cousin, the soboro adzuki bread, 소보로팥빵. The difference between the two is that the latter is stuffed with sweetened adzuki or red beans, making it a little heftier and filling. Another way to describe it would be a red bean/adzuki bread, 팥빵, topped with peanut streusel. However you look at it, this baked bun is delicious and embodies all the best qualities of a Korean bakery: sweet and savory flavors in an enriched dough.
Bread baking and bean cooking are two things that induce a lot of fear in many people–myself included. And so I’ve included a few directions or elements to the recipe that should make it easy to succeed.
FLOUR PASTE/TANGZHONG
Tangzhong is a Japanese technique where a small portion of the flour and liquid in a recipe is cooked into a paste and then added to the dough. This allows the starches in the flour to absorb and retain more water, which makes the bread fluffier, moister, and stay fresh for longer.
COOKING BEANS
I recently purchased the cookbook Cool Beans by Joe Yonan and I’ve adopted his method for cooking dried beans on the stovetop–which doesn’t require soaking them ahead of time. Simply cover the beans with about 3 inches of cold water, bring to a boil and cook uncovered for 10 minutes. Then reduce the heat to as low as your stove can go, cover, and cook for about an hour. I’ve followed this method many times now with success and love how easy it is. Adzuki beans are small and so it only takes about 45 minutes of covered, low heat cooking until they’re done. If you accidentally overcook the beans and they become mush, that’s totally ok and actually good! My filling is supposed to be chunky with a mix of semi whole beans and completely mushed up ones.
As a side note, some adzuki bean fillings are super smooth and others a little more chunky. It’s really about personal preference and what kind of experience the baker wants to eater to have. For soboro adzuki bread, I personally like the chunkier version, and so that’s how I’ve written the recipe.
Happy baking everyone! I hope you like this recipe as much as I do :).

1/4 cup (55 g) brown sugar, packed
1/4 cup (85 g) honey
1/2 teaspoon (3 g) salt
Peanut Streusel
1/3 cup (76 g) butter, at room temperature
3 tablespoons (48 g) peanut butter
1/3 cup plus 1 tablespoon (90 g) brown sugar
1 large egg yolk
1 teaspoon (4 g) vanilla extract
1 1/8 cup (140 g) all purpose flour
1/2 teaspoon (3 g) baking powder
1 tablespoon (8 g) cornstarch
Flour Paste/Tangzhong
1/3 cup plus 1 teaspoon (80 g) water
2 tablespoons (16 g) bread flour
Dough
1/3 cup plus 1 teaspoon (85 g) warm milk*
1 large egg
2 cups minus 2 tablespoons (238 g) bread flour
3 tablespoons (36 g) sugar
3/4 teaspoon (3.8 g) salt
1 1/2 teaspoons (6 g) active dry yeast
2 tablespoons (28 g) butter, at room temperature
Instructions
Sweetened Adzuki Beans
1. Rinse and drain the beans, then transfer to a medium pot. Add fresh, cold water, enough to cover the beans by 3 inches. Bring to a boil and cook uncovered for 10 minutes. Then reduce the heat as low as the stovetop will go, cover, and cook for 45 minutes or until tender.
2. Reserve about 1 cup of the bean liquid and drain the rest. Return the cooked beans to the pot and mix in the brown sugar, honey, and salt. Once everything has incorporated, add 1/2 cup of the reserved bean liquid.
3. Place the pot over medium heat. Bring to a boil, then reduce heat to a simmer. Cook for about 8-10 minutes, stirring once in a while to let the contents reduce. The beans are done with they resemble a thick chili-like stew. If the bean mixture looks too dry, add a little bit of the bean water to get the right consistency.
4. Place in a clean bowl or heatproof container. Cool completely before using. Sweetened adzuki beans can be made up to 3 days in advance and kept in the refrigerator.
Peanut Streusel*
1. In a bowl, cream the butter and peanut butter until smooth. Add the sugar and mix until incorporated. Add the yolk and vanilla extract and combine. Add the all purpose flour, baking powder, and cornstarch and mix until a cohesive dough forms.
2. Break the dough apart into small crumbly, pieces. Cover and set aside at room temperature until needed.
Flour Paste/Tangzhong
1. In a microwave safe bowl, whisk the water and bread flour together until there are no lumps. Microwave at 20 second intervals, whisking in between, until the mixture is thick and smooth like a pudding.
Dough
1. In the bowl of a stand mixer, add the cooked flour paste/tangzhong and slowly whisk in the milk. Whisk in the egg and mix until smooth. Add the bread flour, sugar, salt, and yeast and mix with a spatula.
2. Once the dough roughly comes together, place the dough hook on the stand mixer and mix on medium low speed for 5 minutes.
3. Fold in the butter by hand. Once the butter is roughly incorporated, continue kneading with the dough hook on medium low for 5 minutes.
4. Flour your hands and form the dough into a ball. Transfer to a bowl that’s been lightly greased with oil. Cover and set aside in a warm place. Let rise for 40 minutes to 1 hour and 15 minutes or until doubled in size. To test if it’s ready, flour your index finger and press into the dough, like you’re poking someone. If the dough springs back, let it rise for a little longer. If the indentation remains, the dough is ready.
5. Line two baking sheets with parchment paper.
6. Once the dough has doubled in size, divide the dough into 10 equal pieces (around 50 g each in weight). Shape each piece into a smooth round. If the dough feels too sticky, coat your hands in flour. Let rest for 10-15 minutes.
7. Meanwhile, get the sweetened adzuki beans. Divide into 10 equal portions (around 50 g each in weight) and form into a tight ball.
8. In a small bowl, mix 1 cup water with 1 teaspoon cornstarch.*
9. Generously flour your hands. Get one piece of dough and flatten into a large disk. Place one adzuki bean ball in the middle. Pinch the sides of the dough to seal. Repeat until all the dough pieces have been filled.
10. Scoop two heaping tablespoons of peanut streusel on the countertop. Dip the smooth side of the stuffed dough into the water-cornstarch mixture. press the wet part of the dough into the streusel, flattening the round dough into a disk shape. Make sure to stick as much of the streusel onto the dough as possible. Repeat.
9. Place five pieces of dough on each baking sheet. Carefully reshape each dough into a circle if needed. Loosely cover with plastic wrap and let rise in a warm place for 40 minutes to 1 hour.
10. Preheat oven to 375 degrees or 190 degrees C.
11. Bake for 13-15 minutes, rotating sheets halfway through baking, or until lightly golden. Cool on a rack and enjoy warm or at room temperature. Store in an airtight container for 1 day, or in the fridge for about 1 week.
Notes
The milk should feel warm but not hot (around 95-97 degrees F or 35-37 degrees C).
You will have leftover peanut streusel. Bake at 375 degrees F or 190 degrees C for about 10 minutes or until golden. Use as a topping for ice cream, yogurt, or as a substitute for the crumble crisp in my Easy Apple Crisp for Two.
The water-cornstarch mixture will help the peanut streusel stick to the dough.

Michelle says
Looks good!! Adzuki beans sound so foreign in English and yet so familiar in Korean culture.
This recipe is too complicated for me. haha.
Jessica says
Michelle- I know! I always just think of adzuki beans as “pat.”
Kaylee says
Can I use processed red bean paste instead?
Jessica says
Kaylee- Yes! You can use premade red bean paste.
Kaylee says
hi, for the red bean filling can I use already made canned red bean filling? Would it work for this recipe?
Jessica says
Kaylee- That would absolutely work!
