Ingredients

Sweet Bun

  • 250 g (2 cup) bread flour
  • 10 g (2 Tbsp) powdered milk see note
  • 5 g (1 ⅔ tsp) instant dry yeast
  • 2 g (¼ tsp) salt
  • 45 g (3 1/2 Tbsp) sugar
  • 75 ml (5 Tbs) milk
  • 25 ml (1 ⅔ Tbsp) water
  • 1 egg beaten
  • 37 g (2 ⅔ Tbsp) butter room temperature

Soboro (Streusel)

  • 50 g (3 ½ Tbsp) butter
  • 20 g (1 ¼ Tbsp) peanut butter
  • 75 g (¼ cup + 2 Tbsp) sugar
  • 1 tsp corn syrup
  • 1 egg yolk
  • 100 g (¾ cup + 1 ⅓ Tbsp) all purpose flour
  • 27 g (2 ⅔ Tbs) cornstarch
  • 13 g milk powder
  • 2 g (⅜ tsp) baking powder
  • 1 g (⅛ tsp) baking soda

Assemble

  • Bowl of water or left over egg whites both will work fine

Instructions

  • Make the bun dough. In a stand mixer fitted with a dough hook, sift in the bread flour and powdered milk; add in the yeast, salt and sugar and mix on low speed. Pour in the milk, water and beaten egg. Continue to mix on low-medium speed for about 2-3 minutes until the dough starts to come together but is still very sticky.
  • Add in the butter . Continue to mix in the stand mixer until the dough comes together. The dough should be smooth, and pull off the sides of the bowl neatly when being mixed. (Often takes me somewhere between 11-16 minutes, depending on speed and weather).
    *If kneading by hand, follow similar steps as above. You will most likely need to knead it for a few more minutes. Use the windowpane test to check that the dough is ready.
  • Lightly oil or butter a clean bowl. Place the dough in the and cover. Set aside in a warm spot for about 1 hour to proof the dough until its doubled in size.
  • In the meantime, make the streusel topping. In a medium sized bowl (or stand mixer), mix the butter and peanut butter until smooth. One by one, mix in the sugar, corn syrup and egg yolk. Continue to mix until the batter is smooth without clumps.
  • Sift in the all purpose flour, cornstarch, milk powder, baking powder and baking soda on top of the butter mixture. Using a rubber spatula, mix the flour slowly into the butter mixture. Once it looks crumbly, stop mixing. Set aside.
    *I tend to hit at the dough with the spatula and also make lines down the batter. You don’t want the dough to clump into one mixture.
  • Return back to the bun dough. Lightly flour your working area and divide the dough into 10 equal pieces. Roll each dough into a round piece. Cover and set aside for 15 minutes.
  • Lay some of the soboro crumble on the working surface (or large bowl/plate that has a wide enough flat surface). Reroll the dough back into a round shape. Lightly brush the top of the dough with water (or egg whites). Press the wet side down into the crumble. Place about a Tbsp of the soboro on to the back of the dough as well so the bottom of the bread will also have a bit of crumble.
    *my batter had dried out a bit in the pictures.
  • Lay the roll with the bigger crumble side on top. Cover and set aside for 40 minutes to proof a second time.
  • *the crumbles may pull apart as the dough rises!
  • Preheat your oven to 355 degrees F (180 degrees C). Bake the dough for about 15 minutes, until golden brown. Let cool for a few minutes until at room temperature. Enjoy! Great with a cup of coffee or glass of milk!

Notes

Tip: *recommend using grams/weight but cups/Tbsp for US metrics are available
Temperature: all liquids and butter should be at room temperature
Powdered Milk: This can often be found in the baking section where condensed milk is also shelved. It helps to soften the bread but an additional 10 g (1 ½ Tbsp) of flour can be substituted. https://food52.com/blog/16501-what-is-milk-powder-and-how-can-we-cook-with-it
