About Uncle Biff's California Killer Cookies

Uncle Biff's California Killer Cookies traces its origins back to grandma. Every holiday and birthday, Uncle Biff would anxiously wait for grandma GaGa's cookies to arrive on his doorsteps. That memory of savoring delicious treats served as the inspiration for Uncle Biff's California Killer Cookies, and the recipe proved to be popular.

As Uncle Biff began began sharing cookies he made at his house with family, friends, and colleagues, the demand grew large enough to where he opened his first store in San Diego. These days, the store's "Wall of Fame" showcases the sports figures, celebrities, and local faces that have stopped in to taste the cookies. And the popularity has continued as Uncle Biff expands into the Phoenix area, where a new group of residents can enjoy grandma's recipe.
