Potato Hokkaido Milk Rolls

These Potato Hokkaido Milk Rolls are one of my signature recipes—and the ones that went viral for a reason. Made with the tangzhong method and enriched with potato, they stay incredibly fluffy, tender, and soft for days.

    Dough

    • ¾ c whole milk, warm (95 F)

    To Finish

    • egg yolk wash, for brushing 

    • brown butter

    • flaky salt 


    On the day you're ready to bake, remove the dough from the fridge and portion it into 18 even pieces. Roll each piece into a smooth round and place in your 9x9 square baking pan. The rolls should be about 1 ½ inches apart.

    Cover the pans with plastic wrap and let rise until almost doubled, this takes about 1 hour.

    When the dough is almost doubled, preheat your oven to 400 F.

    Right before baking spray or gently brush the rolls with egg yolk wash. Bake for 20-25 minutes, rotating the pans halfway through baking.

    Once the rolls are done baking, remove them from the oven and brush with brown butter and finish with flaky salt.

Recipe Notes
