People are googling for the recipes for the "lost" candy bars of our childhood, and not getting a nice printable article on the subject--only tedious videos. This web site will now fill an information need:
First...it's not true that there were 25 candy bars that were banned. About twenty candy bar wrappers were banned in 1976 because they were made with dyes that tended to seep into the food inside (it was not always or only candy). The companies could have repackaged the candy bars, and did try with a few brands, but decided these candy bars weren't big sellers anyway. In some cases they were clearly weaker competitors with brands that are still selling well.
But a few of these candy bars might be brought back, with better branding and packaging.
1. Ayds
These chocolates were marketed as weight loss "aids," not candy, although candy is what they were. They were made with artificial sweeteners and chemicals that were fairly toxic. They sold well to dieters, and were reformulated a few times, but then a new wave of attention to a disease called AIDS killed the brand forever.
2. Candy Cigarettes
Cinnamon candies with bright red tips, designed to attract children to the body language associated with smoking cigarettes? Well, that idea didn't fly for long. I don't remember a difference in the flavor between Cigarettes and ordinary Red Hots. Then again I didn't like either one...
3. Space Dust
Same sort of thing as Pop Rocks: lumps of sugar, artificially flavored and colored to suggest fruit, that fizzed on contact with saliva. They just weren't as strong a competitor because parents had heard scary stories about "angel dust" and thought Space Dust was a gateway, horrors. Loss to society? Nil. We still have Pop Rocks.
4. Big Time
Thicker, peanut-enhanced version of the Milkshake bar, q.v. This one might be brought back.
5. Butternut
Butternuts are a native American tree species, with edible nuts, in the walnut family but (I think) much nicer tasting than any other walnuts. Butternut candy bars did not contain butternuts, which would have been one valid reason to ban them (false advertising), but the candy was never banned. I never actually saw one; they weren't a nationally popular brand. They are described as like Snickers with more peanuts. Like the majority of candies that disappeared in the mid-1970s, they came in wrappers with red, yellow, or violet colors that were banned for adding toxicity to the candy, and the company decided not to try different packaging as the candies weren't doing as well anyway. Apparently people who had the choice preferred a higher ratio of sugar to peanuts, as in Snickers.
6. Caravelle
Caramel, lightened with crisped rice and/or pecans, wrapped in chocolate, sold fairly well but not so well that the company bothered designing new wrappers for them.
7. Charleston Chew
Sticky chewy taffy that just might pull out the fillings from teeth that might have got cavities from chewing on too much sugar, already. Some people did like it. Charleston Chew was sold as a long strip of candy guaranteed to make a disgusting sticky mess. Then a different manufacturer bought the brand and repackaged it as bite-sized candies wrapped in chocolate, a little less messy, though when it got into the hands of children... Anyway, although some people liked this confection, more people hated it. It was banned, because the strawberry flavor was actually made with a toxic red dye, but was brought back with a red dye that seemed safer. It just didn't sell as well as other candies.
8. Cherry Humps
The idea might be revived, but they'd need a new name. The original idea was simply chocolate-covered cherries sold as candy bars at checkout counters. The cherries were preserved in "cordial" and wrapped in chocolate. Whole cherries formed little bumps in the chocolate bar. They were dyed red. The FDA objected to the dye. No dye, or a safer dye, didn't sell so well The company tried using chopped cherry bits in cherry-flavored pink nougat to fill chocolate bars. That didn't sell very well either. Apparently customers were emotionally attached to those dyed cherries. Today's customers have not formed such attachments...but real cherries aren't cheap. Fake cherries? Meh. I wouldn't buy them. It would have to be real cherries and, for me to buy candy bars, the price would need to drop back to 50 cents for the small bar, $1 for the large one.
9. Chicken Dinner
The brand was patented about a hundred years ago, when many people thought of salt pork as their primary source of protein (which meant they were actually getting their protein from whole grains and beans, salt pork being mostly fat) and a chicken dinner as a special treat. So, this candy bar was the special dessert treat to be served with the chicken dinner. The chocolate bar was filled with peanuts and caramel, a recipe that worked better as Snickers.
10. Chocolite
Another candy marketed to dieters, this one consisted of real chocolate with air whipped into it so you ingested less chocolate, thus fewer calories and less fat and sugar, with the same size chocolate bar you were in the habit of buying. Europeans actually like this; they buy similar treats called Aero Bars. Chocolite was not a big seller in the US. Perhaps if it cost less than solid chocolate bars, in proportion to the amount of chocolate it contained, the brand might be revivied.
11. Coconut Grove
Wads of heavily sweetened coconut dipped in chocolate, not unlike Mounds. This idea might be revived by someone who doesn't mind that peanuts outsell coconuts in the US. Some people did like the coconut alternative, and still do.
12. Cristy
'Another peanut-nougat-chocolate bar that didn't sell as well as Snickers.
13. Denver Sandwich
I never heard of it, but apparently some people out West liked this version of peanuts, nougat, caramel, and sometimes crispy wafers in a chocolate shell. In the Eastern States we still have Snickers and Twix.
14. Hollywood
Another version of nougat, caramel, and peanuts covered in chocolate in a banned bright red package. I remember eating this one and thinking it wasn't as good as Snickers.
15. Marathon
Just caramel covered in chocolate made a cheap enough bar that the company could afford to make it much longer than competing chocolate bars. As a teenaged candy connoisseur I thought it was boring, but some people did like sticky caramel.
16. Milkshake
This one and the spin-off Big Time brand really were unique. They were made of malted-milk-flavored nougat. Nobody else ever replicated the recipe. It's thought to have involved special processing equipment that was destroyed by a fire. The malted nougat was covered in caramel, then in chocolate. The package was banned for being made with toxic dyes, but the company repackaged the candies and were able to sell them in the late 1970, before the fire.
17. No Jelly
Basically a peanut granola bar that just begged to be slathered with jelly or jam. The package was banned. The candy was fine; newer versions of it are on the market now.
18. PB Max
Peanut butter oatmeal cookies, with peanut butter filling, covered in chocolate...the brand survived into the 1980s but just didn't sell as well as similar cookies that were packaged as cookies.
19. Powerhouse
Caramel, peanuts, and chocolate fudge wrapped in chocolate. The wrapping was banned; the company was able to sell the candy in a different package until a corporate merger prompted the decision that it wasn't selling as well as Snickers.
20. Reggie
Caramel and peanuts coated with chocolate sold as round, baseball-shaped souvenirs of baseball star Reggie Jackson during Jackson's active career. He retired about the time the company had to repackage the candy, so they didn't bother.
21. Seven Up
There were several different versions, some cheaper than others, of the chocolate bar consisting of seven distinct bite-sized pieces of chocolate wrapped around different fillings, to be eaten one piece at a time or more than one at a time. The most common version had mint, nougat, butterscotch, fudge, coconut, buttercreme, and caramel fillings. Other fillings included peanuts, chopped brazilnuts, almond pralines, butterscotch, dark chocolate "truffle" candy, vanilla custard, Irish Cream, pistachio nougat, maple toffee, peanut butter, and pineapple. The FDA banned one wrapper and some of the sweeteners used with some of the fillings. Still, these chocolate bars were popular and survived repackaging easily--they'd been repackaged to advertise new flavor mixes several times before. What they did not survive was a lawsuit for copyright infringement. The company tried marketing chocolate bars with sections of different fillings in the 19808s and 1990s, but seven seemed to be the magic number for bites of different candy and apparently nobody wanted to try renaming the candy anything like "Sampler Seven."
22. Snik Snak
Wafers layered with chocolate, like Twix. People who lived in places where this alternative brand was sold say it was different from Twix. I wouldn't know.
23. Triple Decker
Layers of milk chocolate, white chocolate, and dark chocolate, on top of each other and all covered in dark chocolate, so that the different kinds of chocolate melted together in the mouth when people bit into one very thick bar of pure chocolate. Some people liked the candy (I don't think I ever saw it), but changing the wrapper was the least of the company's worries. The dark chocolate coating tended to stick to whatever wrapper they used. Some people thought the texture of the chocolate needed to be lightened with nuts. That wasn't easy to make work, either. The idea of just packaging three separate thin bars of chocolate in a stack, so that people could bite into them together or separately, doesn't seem to have been considered.
24. Walnut Crush
This one was unique: chopped walnuts in white nougat with a thin outer shell of chocolate. Price may have been the reason why nobody tried repackaging this candy bar. Enough people like walnuts that it might sell, though not, of course, as fast as peanuts.
25. Whiz
Peanuts suspended in marshmallow, covered in chocolate, just might have worked if the company had worked at marketing them. Mallo Cups will never sell as well as Reese's Cups but they do sell.
Disqualified for This List
Mars Bars consisted of nougat, caramel, and almonds wrapped in chocolate. They don't qualify for this list because they were sold in the US into the early 1980s. In 1982 Sue Townsend had an American character who didn't recognize them and had to be told about them by other children when he visited England. This is anachronistic. Americans knew about the whole-almond bars, though perhaps American candy munchers didn't want to risk their teeth actually eating them. Or maybe it was the fatal commercial where that baritone who'd done the other commercials about Mars Bars being "out of this world," and so on, said "You get big crunchy nuts in a Mars Bar." The commercial aired around the time kids my age were discovering that "big crunchy nuts" had an alternative meaning. It always seemed to me that the candy bar died of embarrassment. Anyway it was officially discontinued in the 1980s due to declining sales, then brought back as Almond Snickers.
As a bonus idea, one of the videos about these vanished candy bars self-advertises with a picture of a once popular dessert that was never marketed as a candy bar--white "seafoam" or "divinity" candy with chopped-up gumdrops suspended in it like stained glass. Seafoam candy was cheap, though hard to make. It was a popular party dish because it needs teamwork; someone has to pour hot syrup slowly over egg whites while someone else is beating them. In the 1970s fear that the hot syrup didn't cook the egg enough to kill possible salmonella pushed seafoam candy completely out of fashion. White nougat and white chocolate with bits of fruit jelly candy, possibly in the classic seven-bites arrangement, just might be a marketable idea.
