Margaret Burnham Cottage Candies was a Bay Area chain of candy stores, founded in 1925 by George P. Ballachey. It's best remembered in Oakland by the Cape Cod-style building on Telegraph that was later Hooper's Chocolate, which opened in 1930. 1
There were outlets in Oakland, Alameda, Berkeley, San Francisco and Reno, Nevada, but the candy was processed in Oakland.
