Traubel's association with the Metropolitan Opera ended in 1953; General Manager Rudolf Bing chose not to renew her contract after expressing disapproval of her radio and TV appearances alongside the likes of Jimmy Durante, and her wish to expand her lucrative career in major supper and night clubs. Traubel went on to appear at the Copacabana, as well as in many cameo television roles. After her Met career, she appeared on Broadway in the Rodgers and Hammerstein financial failure, "Pipe Dream", playing a bordello madame with a heart of gold and the voice of Isolde. Additionally, she appeared in the films "Deep in My Heart", "The Ladies Man" and "Gunn". She also appeared opposite Groucho Marx as Katisha in a Bell Telephone presentation in an abridged performance of Gilbert and Sullivan's "The Mikado". Traubel's last night club appearance was with Jimmy Durante at Harrah's Lake Tahoe in 1964.
