To answer the question, the U.S. TV mom who sang about "Wessonality" in TV commercials for Wesson Cooking Oil was Florence Henderson. She had previously become most famous for her role as mom on "The Brady Bunch" (1969 - 1974). One of her next work projects would include working for the Wesson Cooking Oil Company.

Henderson was the spokeswoman for the cooking oil brand from 1974 to 1996. During that time, she made many commercials where she sang the Wesson jingle about "Wessonality". She actually did this for over twenty years.

She was also able to host a cooking show on TNN, "Country Kitchen", and did ads for Prange's, a former state of Wisconsin department store chain. Next, Henderson co-hosted the short-lived NBC morning talk show "Later Today" (1999–2000). Jodi Applegate and Asha Blake appeared on the show with her.
