Founded by dairy farmer Frank Mullen Sr. and his sons, Frank Jr. (Moon), Weber and Gerry, Mullens Dairy Bar began as a brick-and-mortar operation where the Mullen’s family bottled their milk and sold a variety of dairy products including butter and cream. By the 1940's, the three brothers added ice cream production to the mix.


Mullen’s Dairy Bar is known for its creamy and delicious ice cream. We sell small batch homemade ice cream in retail outlets throughout Wisconsin and we are more than happy to scoop it up for you in one of our shops.
