Yesterday’s Mother Goose and Grimm:
A POP (phrasal overlap portmanteau) incorporating a pun: Betty Crocker (see below) + cocker spaniel (the dog breed), with Crocker / cocker in the middle.
Betty Crocker is a fictional character used in advertising campaigns for food and recipes, originally by the Washburn-Crosby Company, today General Mills, an American Fortune 500 corporation which owns the brand name and trademark. Betty epitomizes a motherly, caring and knowledgeable homemaker offering cooking and housekeeping advice. A portrait of Betty Crocker, first commissioned in 1936 and revised several times since, appears on printed advertisements and product packaging. On television and radio broadcasts, Betty Crocker was acted by several actresses, most notably by Adelaide Hawley Cumming between 1949 and 1964.
Sorry, I couldn’t resist the suggestive lure of fudge brownies.
