Korean streusel bread or Soboro-ppang (소보로빵) is a light fluffy yeast bread with a crumb topping made with peanut butter. Due to the amount of sugar it is not gout friendly. With the eggs, butter and milk it is not vegan. But I am sure it could easily be made vegan. My wife and girls love Soboro-ppang so we decided to document the process but they are not on my menu.
Every time we go to H-Mart during the checkout process my wife will disappear. Nothing to worry about she is at the bakery for a little shopping. About the time we get on the highway she will open the bag from the bakery and the first thing she will eat is of course Soboro-ppang.
She has spent a lot of time working on this recipe, reading Korean food blogs and watching YouTube videos. She says its about 90%. She may never get it just right, kind of like me with pizza dough.

The recipe is broken up into two parts. One for the bread and one for the crumb (streusel like) topping.
Ingredients for the dough:
Bread flour: Bread flour is a high protein very strong flour. It gives dough lots of strength.
Cake flour: Is a finely milled low protein flour. It's used to make cakes light and fluffy. Can you use all purpose flour instead of mixing the two? Possibly but when it comes to Korean streusel bread I just go along with the program.
Sugar: Sugar will feed the yeast so that it will develop quickly and act as a lubricant for the bread.
Salt: Let's face it recipes need salt to balance out the flavors.
Dry or powdered milk: To add flavor and help with browing the outside of the bread.
Yeast: Yeast is what will cause the rise in our bread and give a yeasty flavor. It also makes the house smell nice while cooking.
Milk: We use two percent milk but you can use what you have.
Egg: Eggs help to lighten the texture of the bread.
Butter: Softened (let it come to room tempature) I am sure that there is a chemistry reason but butter will make the bread richer.
Ingredients for the crumb topping:
Butter: Yep lots of butter in the topping to help with the browning.
Peanut butter: To give a nice flavor to the buns. We used a smooth natural peanut butter but chunky works great. Perhaps you could even grind up some peanuts and add to the crumb topping. That might push the recipe to 92%.
Raw sugar: The sugar we used is from Korea labeled as organic brown sugar. But to me it looks like turbinado sugar.
Honey: The topping needs some kind of thick sweetener. We used honey but corn syrup is probably more common.
Egg: To help bind the topping and to make it richer. We will also brush some of the egg on the bread to help the topping stick. We used one large egg that had been beaten.
Dry Milk: For flavor without adding moisture.
Salt: Got to have some salt
Baking powder: Not sure why this is needed I just go along with the program. Remember safety first in the kitchen. Actually it helps to lighten the crumb.
All purpose flour: The type of flour here is not to important. In fact I would like to try grinding up some oats and mixing with flour.
The volume to crumb topping is more than what you will need. But in this house you must have enough topping. To keep from having to much left over just cut back on how much flour you use.
Let's make the bread dough. Add all of the dry ingredients (dough only not the topping) to a mixing bowl. We used the stand mixer so we added to that bowl. Then gave a quick mix with the whisk.
Then we placed the bowl on the stand mixer and added the wet ingredients (milk and egg), reserving the butter. Turned the mixer on setting one. Mixed a little then went to setting two. Mixed a little then used a spatula to scrape down the bowl. After everything was combined we started to speed up the mixer. Finally mixed on setting eight for three minutes.
Yep we beat the crap out of the poor dough. When we lifted the mixer the dough fell off of the hook. After this the dough needs to rest.
Note: You could knead by hand but it takes a lot of work. I am to lazy and as they say ain't nobody got time for that.
Put some (about a teaspoon) flour of your surface and scrape your dough out of the bowl and form it into a ball. The dough is very sticky but just do the best that you can. Cover with plastic wrap and let it rest for ten minutes.
After the dough has rested it will be a lot more elastic (stretchy) it is ready for a little hand kneading. Put a touch (about a teaspoon) of flour on your surface and knead for three or four minutes. Then form it into a ball and add to a bowl and cover. Let it rise until doubled in volume.
The time to double in volume will depend upon the tempature and humidity in the air.
We have an electric bread proofer that we set on 120F. The bowl was placed inside and it took about one hour. You could turn your oven on just long enough for it to start to get warm then turn it off. Put your dough inside and leave the light on. Just make sure your oven is not hot.
After the dough has doubled in size punch it down and form into individual balls. This time we make twelve but eight is probably the best size.
Cover the balls and let them rise until close to doubled in size. This took about forty five minutes in the proofer at 120F.
During this rize is a good time to make the crumb topping.
Now they are ready to add the crumb topping.
First step to our crumb topping is mixing the peanut butter and butter. The butter does not have to be completely soft or even fully mixed.
Then mix in the sweetners, in this case honey and raw sugar. You want to the sugar to mostly dissolve. But little crunchy bits of sugar are a sweet thing.
Then add about 1/3 of a large egg that has been beaten. We save the other 2/3 of the egg for an egg wash. But if you want add all of the egg at this point. And give a good mix.
Now mix in the dry milk, salt and baking powder.
Dump in the all purpose flour and use your hands to mix it in. You want it to have a course uneven texture. You now have your crumb topping.
When your dough balls are ready roll them into balls and brush with egg or milk. We used egg. And top with crumb mixture.
Note: Instead of egg or milk mix cornstarch with water and brush on to the dough balls. The main purpose of the egg, milk or cornstarch it so that the crumb topping sticks to the dough.
Place your dough balls on a sheet pan lined with parchment paper and add more crumb mixture and press them kind of flat. The more crumb topping the better.
Start preheating your oven to 350 F and let them rise until they have almost doubled in size.
Place them in the oven and cook for twenty minutes. At about the fifteen minute mark turn your sheet pan around 180 degrees. So that they brown evenly. For this batch we forgot to do that and some more brown than others. If you have a convection oven this is not as big of an issue. Also after the fifteen minute mark keep a close eye on them. With all of the sugar in the topping they can go from brown to burn rather quickly.
