Food trends move fast. In the past decade, some products went from impossible to avoid to barely seen in less than a year.
That speed matters for restaurants, grocery chains, and shoppers, because hype can drive real spending before demand drops just as quickly. Here are 10 foods that briefly looked huge in the U.S. and then faded fast.
Rainbow Bagels
Rainbow bagels became one of the clearest examples of a food trend powered by photos first and taste second. Around 2015 and 2016, brightly colored swirled bagels spread from a few New York shops to bakeries across the country. Stores sold out early, and long lines formed as customers chased a product that stood out on Instagram feeds.
The appeal was obvious on camera. The bagels were vivid, playful, and easy to share online, which helped them travel far beyond their original local market. Several independent bakeries and copycat chains leaned in, offering matching rainbow cream cheese and other colorful add-ons.
But the craze cooled quickly. Consumers who tried them often found that the look mattered more than the flavor, which was usually just a standard sweetened bagel. Once the novelty wore off, many shops stopped pushing them, and most major grocery chains never gave them lasting shelf space.
By the following year, rainbow bagels had mostly shifted from mainstream craze to occasional specialty item. They still pop up from time to time, but the national obsession was short-lived and tied closely to the early peak of highly visual social media food culture.
Activated Charcoal Ice Cream
Activated charcoal foods had a brief but intense run in the U.S., especially in 2017. Ice cream, lemonade, lattes, and burger buns turned jet black, creating a striking look that drew crowds to dessert shops and cafes. Black soft serve in particular became a summer headline item in several cities.
Retailers and restaurants marketed the products as edgy, trendy, and in some cases wellness-adjacent. That last part became a problem. Medical experts and regulators noted that activated charcoal can interfere with the absorption of some medications, including certain prescriptions.
The U.S. Food and Drug Administration has long restricted activated charcoal as a food color additive in many uses, and that gave some operators pause. In New York City, health officials drew attention in 2018 to the ingredient’s regulatory status, prompting renewed scrutiny around black-colored desserts and baked goods.
That attention helped puncture the trend. Once the novelty wore off and the health questions became better known, many shops moved on. Within roughly a year of peak visibility, charcoal ice cream had largely disappeared from everyday menus, surviving only in niche pop-ups and occasional seasonal promotions.
Freakshakes
Freakshakes were hard to miss at their peak. These oversized milkshakes, piled with donuts, cookies, whipped cream, candy bars, syrup, and cake slices, exploded in popularity in the mid-2010s after gaining traction in Australia and then in U.S. dessert shops.
For a brief stretch, restaurants treated them as centerpieces rather than drinks. Some versions topped 1,000 calories, and others likely ran far higher depending on toppings. Their value was visual and social. One towering shake could bring in a group, a camera phone, and a lot of free promotion online.
The problem was repeat business. Many customers ordered one once for the spectacle, then had little reason to return for another. They were expensive, messy, difficult to consume, and often more about excess than flavor balance.
As menus shifted back toward items people would buy regularly, freakshakes lost momentum. By the next year in many local markets, they had moved from must-try item to leftover novelty. A few dessert bars still offer them, but the short national boom ended fast.
Unicorn Frappuccinos and Copycat Unicorn Foods
In April 2017, Starbucks launched the limited-edition Unicorn Frappuccino in the U.S., Canada, and Mexico. The brightly colored drink mixed sweet and sour flavors with a pink-and-blue visual style designed to attract attention immediately. It did exactly that, generating a wave of store traffic and widespread coverage.
The drink also set off a larger unicorn food boom. Bakeries, coffee shops, and supermarket brands rushed out unicorn toast, unicorn cupcakes, unicorn popcorn, and colorful pastel snacks that followed the same visual formula. For a few months, the look seemed to be everywhere.
But the original product was intentionally temporary, lasting only a few days. Baristas publicly complained about the workload and mess, and many customers treated it as a one-time novelty rather than a repeat order. Its cultural impact was bigger than its staying power as an everyday food.
By 2018, the broader unicorn trend had already faded sharply. Some colorful desserts remained, but the label itself quickly became dated. What looked like a major shift in consumer taste turned out to be a short-lived branding and social media moment.
Cloud Eggs
Cloud eggs had one job: look dramatic in photos. The dish, which separated egg whites from yolks, whipped the whites into a fluffy mound, and baked the yolk in the center, briefly surged online in 2017. Lifestyle blogs, morning shows, and home cooks all took a turn with it.
The idea sounded fresh because it made an ordinary breakfast ingredient seem new. Eggs were already affordable and familiar, so the barrier to trying the trend was low. That helped it spread quickly across kitchens and food media.
Still, the dish never solved a practical problem. It took more work than frying or poaching an egg, and the final result was not notably better for most eaters. In many home kitchens, cloud eggs were made once for a photo and then abandoned.
That pattern made the trend burn out fast. Unlike avocado toast or overnight oats, cloud eggs did not fit naturally into everyday routines. They were a classic example of a food that generated attention without building a lasting place in the American breakfast lineup.
Mug Cakes
Mug cakes had several mini-booms, but one of the biggest came in the early 2010s and returned heavily during short recipe-craze cycles on social media. The pitch was simple: mix a few ingredients in a mug, microwave for a minute or two, and get instant cake without baking a full dessert.
For college students, busy workers, and small households, that sounded ideal. Publishers released recipe books, food sites published endless variations, and stores marketed cake mixes and accessories built around the idea. It felt efficient, cheap, and perfectly matched to small-space living.
The weakness became clear after the first wave. Texture was often rubbery or uneven, ingredient ratios were fussy, and results varied widely by microwave power. Many consumers discovered that the promise of bakery-style cake in minutes rarely matched reality.
That gap between expectation and result hurt staying power. Mug cakes never fully vanished, but the massive trend did. After a burst of popularity, they settled into the background as an occasional convenience recipe rather than the dessert revolution they briefly seemed to be.
Watermelon Pizza
Watermelon pizza was another warm-weather food craze that briefly punched above its weight online. The idea involved slicing a round of watermelon into wedges and topping it with yogurt, berries, coconut, nuts, or other fruit to mimic a dessert pizza. It showed up widely in summer recipe coverage around 2016 and 2017.
It checked a lot of trend boxes at once. It was colorful, easy to photograph, relatively healthy-looking, and simple enough for family content and party spreads. It also fit the growing demand for lighter desserts and kid-friendly fruit ideas.
But as an everyday dish, it had obvious limits. Watermelon releases a lot of liquid, toppings slide, and the final product has to be eaten quickly. It worked better as a social post or picnic gimmick than as a practical recipe people would make repeatedly.
That made its popularity fleeting. Once summer moved on and social feeds found newer fruit hacks, watermelon pizza largely disappeared from the mainstream conversation. It remains familiar to trend watchers, but it never became a durable staple in homes or stores.
Cookie Dough Cafes
Edible cookie dough shops spread rapidly across the U.S. around 2017 and 2018. Businesses sold ready-to-eat dough made without eggs and with heat-treated flour to address safety concerns that had long made raw dough risky. For a while, the concept looked like a major dessert category.
The growth was noticeable in big cities, college towns, and mall-heavy retail areas. Shops offered scoopable dough in cups, cones, and pints, often in flavors modeled on ice cream counters. Consumers liked the nostalgia factor and the sense that they were getting a forbidden treat made safe.
Still, the business had a narrow lane. Many customers liked edible cookie dough as a novelty but not as a repeat purchase. The texture was rich, the product could feel heavy after a few bites, and dedicated storefronts faced the same rent pressures as many single-item dessert concepts.
Within a year in many markets, the rush had cooled. Some brands survived by adding shipping or packaged retail items, but the broad storefront craze eased quickly. What looked like a major new dessert habit turned out to be a shorter-lived specialty splurge.
Dalgona Coffee
Dalgona coffee became one of the signature foods of the early pandemic period in 2020. The drink, made by whipping instant coffee, sugar, and water into a thick foam and spooning it over milk, spread internationally through TikTok, YouTube, and home cooking coverage.
Its timing was a major factor. Millions of people were spending more time at home, trying pantry-friendly recipes, and looking for low-cost rituals. Instant coffee sales got a boost in some markets, and the drink became a symbol of lockdown-era kitchen experimentation.
But it was also labor-intensive unless people used mixers, and many found the taste too sweet or too dependent on instant coffee quality. Once cafes reopened more fully and routines normalized, the need for this kind of homemade showpiece faded quickly.
By 2021, dalgona coffee had already lost much of its peak visibility in the U.S. It never disappeared entirely, but the craze itself did. It remains one of the clearest examples of a food trend tied tightly to a specific moment and then left behind.
Butter Boards
Butter boards surged in late 2022 after social media creators popularized serving softened butter spread across wooden boards and topped with flaky salt, herbs, honey, citrus, or edible flowers. Hosts presented them as an alternative to charcuterie boards, and the idea spread fast ahead of holiday gatherings.
The trend benefited from an established board culture. Consumers were already used to grazing platters, and butter boards felt both rustic and visually rich. Food brands, creators, and party planners quickly joined in, pushing endless variations for entertaining season.
Then came the backlash. Some chefs and food safety observers questioned the practicality and hygiene of communal dipping, especially at larger gatherings. Others simply found the concept wasteful or overly messy, particularly when compared with regular bread-and-butter service.
That criticism arrived almost as fast as the trend itself. By the following year, butter boards had largely slipped from mainstream food coverage and party menus. They remain a memorable social media flashpoint, but like many fast-rising food crazes, they burned bright and faded quickly.
