Doubling as a retail cookie shop and food manufacturer, Uncle Biffs California Killer Cookies bakes from 650 University Ave in Hillcrest’s 92103 ZIP code. The retail-and-wholesale model sells individually and ships bulk orders to grocery stores and corporate accounts, a dual-channel cookie operation on the same University Ave corridor as Kona Coffee Co.'s 100% Hawaiian Kona roasts. The bakery uses natural ingredients across more than a dozen signature flavors, skipping artificial preservatives and synthetic additives. Diners grabbing lunch at Common Stock in the neighborhood often swing by for a cookie dessert course afterward. Uncle Biffs’ food-manufacturing operation supports wholesale distribution to cafes, offices, and retailers stocking locally produced baked goods.
