I would put the Langendorf (Southern California) baked "Mickey" Cakes and Langendorf pastries at the top of the list. My father was a route salesman for Langendorf Cakes and Cookies in a white truck while Langendorf Bread was distributed in yellow Barbara Ann trucks out of the same Depots.
Those banana "flips" were a sorry incarnation of one of Langendorf's best "Mickey" snacks, the "Banana Dream" these were two soft cake cups filled with an banana cream that amounted to a soft crusted banana cream pie. The current taco shaped atrocity is really sweet and tastes nothing like the original.
Langendorf had many of the cakes that Hostess had but with different names:
Creme Boats (3pk) = Twinkies
Boom Booms = Ding Dongs
Lil' Devils = Chocodiles
Chocolate and orange cupcakes
A version of the snowball
Their product line included a mini pound cake, mini-donuts that came in miniature versions of the full size boxes (instead of cellophane), and this awesome chocolate wonder called a "Fudge Bar". Under the Langendorf name my dad carried snack size cinnamon rolls, bear claws, butterhorns, and fruit pies with more flavors than you could shake a stick at, full size (like Entenmann's and Svenhard's) pastries like Apple Strudel, butterhorns, Bear Claws, and Cinnamon Rolls (with and without raisins), a full sized pound cake and a Fruit Loaf during the Holidays. He also carried fig bars, "vanilla wafers", and all sorts of Cookies of the "Mother's" varieties like Chocolate Chip, Sugar, Oatmeal, etc.
The funny thing is here in Southern California, Langendorf delivered mainly exclusively to the 7-11 chain, mom and pop grocery and liquor stores and the occasional large independant grocer. At the time, only Hostess and Dolly Madison delivered to the large chain supermarkets but were not allowed in 7-11's. Barbara Ann was mainly a Restaurant and institutional bakery delivering to the occasional mom and pop/independant grocer.
My dad seemed to always have run-in's where he had to share shelf space with a Hostess or Wonder driver (never with Dolly or Weber's though) he used to say (I hate Hostess!) and through an ironic twist of fate, Dolly Madision bought Langendorf Cakes & Cookies, so he was a Dolly guy for while (Dolly Madison cut most of the Langendorf products and repackaged a few under the Dolly label) then IBC sold Dolly to Hostess, and later bought it, Hostess and Wonder so my dad became a Hostess driver.
He retired a couple of years back and laments that the bakery delivery business is not what it once was and is happy to have gotten out. The parent company of Wonder/Hostess filed for bankruptcy and is still trying to get back on it's feet.
Sadly none of the really good Langendorf-Mickey Cakes that I knew back in the late 70's through late 1980's have survived.
