Soboro Ppang · soboro ppang · Korean streusel bread
Ten soft, sweet yeast buns with a crisp, peanut butter streusel topping, shaped by hand and baked until golden.

Soboro-ppang pairs a soft, sweet yeast bun with a rough crumble baked over its surface. Jennifer’s ten-bun formula uses a bread-flour dough enriched with milk, egg and butter, then adds a peanut-butter streusel made with flour, sugar, butter, yolk and leavening. The topping is part of this version’s identity, not a garnish that can be omitted without changing the source recipe.
The recipe author identifies the bread with Korean bakeries and explains “soboro” as the crumble topping and “ppang” as bread. Her page documents a present-day home formula; it does not date the earliest appearance of the bread or establish a precise birthplace. The ingredient list includes peanut butter, wheat flour, milk and egg, all of which must remain visible to readers with allergies.
The yeast, salt and sugar first meet the sifted bread flour and milk powder. Milk, water and beaten egg hydrate the dough before butter is worked in. The dough starts sticky, then becomes smooth and pulls from the mixer bowl after about eleven to sixteen minutes with the butter. That kneading develops the elastic structure needed to hold gas and expand into a soft bun. Hand kneading is also described, although the page gives no exact hand-kneading time.
During the first one-hour proof, the streusel can be mixed separately. Creaming the two butters with sugar, syrup and yolk creates the moist base; sifting the dry flour, starch, milk powder and chemical leaveners over it keeps the topping crumbly. Stop mixing when the ingredients form loose crumbs rather than a smooth paste. The topping can dry while it waits, so avoid overworking it when returning to the buns.
Both mixtures contain raw flour and egg before baking. CDC warns against tasting raw dough and recommends baking flour-containing dough according to the recipe, with clean hands, tools and surfaces after handling. No separate time or temperature limit is added here.
After the first rise, divide the dough into ten pieces, round them and cover them for a fifteen-minute rest. Spread the crumble in a broad layer. Reround each dough ball, wet its top with water or leftover egg white, and press that side into the topping. The source also places about a tablespoon of crumble underneath, then turns the bun so the more heavily coated side faces up. This gives the distinctive pebbled cap while leaving a little topping at the base.
A forty-minute second proof lets the shaped buns rise before baking; some crumble may loosen as they expand. Bake at 180°C for about fifteen minutes until golden brown, then cool briefly. The source gives no internal-temperature measurement or storage instructions, so the bake time and colour remain its recipe cues rather than validated safety limits.
Jennifer describes soboro ppang as a Korean bakery sweet bun and explains the name as streusel topping over bread. The page is a modern home recipe, not a historical account, so it does not establish when or where the bread first appeared.
