Sour Rabbit Bakery

Sour Rabbit Bakery is Atsuko Hammann’s (Japan) and Rolf Hammann’s (Germany) sourdough bakery in Kansas City’s Northland — opened March 4, 2025. Japanese milk bread, German-style cakes, sourdough croissants that sell out by noon on Saturdays. Started from a home bakery three years earlier; the name honors Atsuko’s sourdough starters and her birth sign in the Japanese zodiac.

Description

Sour Rabbit Bakery is a story of two countries meeting in a Kansas City Northland strip mall. Atsuko Hammann grew up in Japan; Rolf Hammann grew up in Germany. Together they brought the flavors of both food traditions to a sourdough-focused bakery that opened on March 4, 2025, at 7715 NW Prairie View Road. Atsuko became obsessed with natural sourdough fermentation three years earlier, launching a home bakery that built a following before the permanent space opened. The name Sour Rabbit honors the sourdough starters she tends — one from wheat flour, another from Japanese sake — and the rabbit, her birth sign in the Japanese zodiac. The result is a bakery that moves between cultures fluidly: shokupan (Japanese milk bread) sits alongside German-style cakes and sourdough croissants that regularly sell out before noon on Saturdays. Within days of opening, Atsuko sold out of every item she had made.

Tier classification

Tier 2 — Japanese-born and German-born immigrant co-owners, KC-dedicated. Atsuko Hammann is from Japan; Rolf Hammann is from Germany — neither KC-born/raised.¹² They chose Kansas City as their home base and opened Sour Rabbit Bakery in the Northland as a brick-and-mortar expansion of Atsuko’s home bakery operation. They are immigrant entrepreneurs who have committed to building their business in the KC metro. Tier 2 confirmed: immigrant-owned, KC-dedicated operators, opened 2025.
