The croffle — a buttery croissant pressed in a waffle iron until golden and caramelized — has evolved from a niche pastry experiment into one of the defining food trends of the 2020s. First demonstrated in a 2015 Food & Wine video and formally debuted by Irish pastry chef Louise Lennox in 2017, the concept only truly ignited when South Korea's café culture embraced it in 2018–2020. A pandemic-era Instagram post by K-pop singer Kang Min-kyung, combined with TikTok virality and the trend's sheer home-cooking simplicity, propelled the croffle from Seoul street food to a global dessert category now found from Flushing, Queens to Singapore to Tokyo. Unlike its spiritual predecessor the Cronut, the croffle's accessibility — two ingredients, five minutes, no deep fryer — gave it lasting power well beyond novelty status.
The croffle's invention has no single undisputed creator, though three distinct claims form a clear timeline. The earliest documented use of the term appears in a Food & Wine YouTube video published December 18, 2015, in which New York–based contributor Katie Quinn demonstrated pressing thawed puff pastry in a waffle iron and called the result a "croffle." Etymological researcher Barry Popik has confirmed this as the first recorded coining.
The more widely credited inventor is Louise Lennox, an Irish pastry chef and TV3 host, who developed the croffle as the centerpiece of a pop-up bakery called "La Petite Boulangerie" at No. 9 Camden Street, Dublin, running July 10–22, 2017, in collaboration with bakery chain Cuisine de France. Lennox created both sweet and savory variations — avocado and feta, pulled pork and apple slaw, lemon cheesecake, Nutella and banana, s'mores — and generated significant Irish media coverage. Wikipedia currently credits Ireland as the croffle's place of origin and Lennox as its creator.
The third and arguably most consequential chapter began in November 2018, when Seoul café Aufglet (아우프글렛) in the Geumho-dong neighborhood became the first Korean establishment to serve croffles. Founded by four friends, Aufglet offered its signature croffle topped with homemade ice cream and cinnamon powder. While South Korea did not invent the croffle, it unquestionably transformed it from a curiosity into a cultural institution. Some recipe blogs incorrectly attribute the invention to Korea — the evidence points to the concept emerging in the US and Ireland but being popularized and perfected in Seoul.
The croffle's path from Dublin novelty to worldwide phenomenon ran directly through Seoul's café culture. After Aufglet's 2018 debut, the trend spread steadily through the city's dense network of independent cafés. Then came two accelerants in 2020 that turned a local trend into a national obsession.
The COVID-19 pandemic sent millions of Koreans home with time on their hands. Croffles became an ideal quarantine project: accessible ingredients, minimal equipment, visually dramatic results perfect for social media. Waffle iron sales reportedly surged approximately 300% between May 2019 and May 2020. Then on April 7, 2020, K-pop singer and actress Kang Min-kyung of the duo Davichi posted on Instagram that the croffle was "really, so, so, so tasty." With over 650,000 YouTube subscribers and deep ties to K-drama culture (her music appears in Descendants of the Sun and Crash Landing on You), Kang's endorsement is widely cited as the single most pivotal moment in the croffle's rise to mainstream Korean popularity. The South China Morning Post ran a feature headlined "How K-pop's Kang Min-kyung started a 'croffle' craze."
By 2020–2021, the croffle had cemented itself as a staple "K-dessert" alongside dalgona coffee, Korean corn dogs, and goguma bbang, transcending trend status to become a permanent fixture of Korean café menus. Major establishments began limiting daily production — Saddler Haus in Garosu-gil famously caps its cheese-corn croffles at 60 per day, one per customer, with lines routinely wrapping around the building.
The international spread followed Korean cultural exports. Croffles reached the US by late 2020, first appearing in Flushing, Queens and LA's Koreatown. TikTok videos tagged #croffle accumulated tens of millions of views between 2020 and 2023, with Food Republic declaring in September 2023 that "TikTok's Croffle Will Change How You Use Your Waffle Maker." The trend subsequently spread to Singapore, Thailand, Hong Kong, Japan, Canada, Indonesia, India, the Middle East, and Europe. In each market, the croffle adapted to local tastes — matcha versions in Japan, snow crab mentaiko in Singapore, Biscoff-topped variations in Europe — while the Korean aesthetic of elegantly plated croffles with ice cream and fruit remained the dominant visual template.
The croffle's versatility begins with dough choice, and there is a clear hierarchy among the four main approaches.
Store-bought frozen croissants represent the consensus best option for most makers. Brands like Trader Joe's frozen mini croissants and Whole Foods refrigerated croissant dough deliver authentic laminated butter layers — flaky interior, crispy exterior — without the labor of from-scratch preparation. The technique is straightforward: thaw overnight in the refrigerator (never cook from frozen), optionally flatten slightly with your palm, roll generously in sugar, and press in a preheated waffle iron at medium heat for 3–4 minutes. Multiple sources emphasize that medium temperature is critical; high heat burns the sugar coating before the interior cooks through.
Puff pastry sheets offer the second approach. Thaw the pastry, roll it out, cut into long triangles, and roll each into a croissant shape before sugar-coating and pressing. The results are ultra-crispy but notably denser than true croissant dough because puff pastry lacks yeast and won't rise. Cook time is shorter — roughly 1.5–2 minutes — and the texture skews entirely toward crunch rather than the flaky-soft interior that defines the best croffles.
Pillsbury or refrigerated crescent roll dough is the cheapest and most accessible option. Unroll the dough, separate into triangles, roll into crescents, and proceed normally. However, multiple sources caution that crescent rolls are not true laminated dough and produce results that are "more bread-like" with fewer buttery layers. As one recipe developer noted: "You can still get the look and softness, but it won't have the same flaky layers as using real croissant dough."
Homemade laminated croissant dough yields the most impressive results but demands significant time and skill. The traditional method involves making a yeasted dough, creating a cold butter block, and performing multiple envelope and letter folds with chilling periods between each. Roll the finished dough to quarter-inch thickness, cut triangles, shape into croissants, and cook at approximately 375°F (190°C) for 4–5 minutes. Shortcut versions exist that use grated frozen butter and simplified folding techniques to reduce the process from a full day to a few hours.
The caramelized sugar shell is the croffle's defining textural feature. The standard technique involves rolling the shaped dough in a shallow bowl of sugar before pressing — granulated white sugar is most common, though caster sugar, brown sugar, and Belgian pearl sugar all produce excellent variations. Pearl sugar creates the most dramatic effect: chunky crystals that don't fully melt, producing chewy-crunchy pockets reminiscent of Liège waffles. Some makers brush the dough with egg wash (one egg beaten with a tablespoon of heavy cream) before sugaring to improve adhesion and add a golden sheen. The science is straightforward: sugar caramelizes at 320–360°F, well within a waffle iron's operating range, while the Maillard reaction between butter proteins and sugars deepens the browning. Critically, the caramelized shell continues to harden and crisp after removal from the iron, so croffles should cool on a wire rack rather than a plate.
A Belgian-style waffle maker with deep wells is the preferred equipment, as it creates more surface area for caramelization and accommodates the thickness of croissant dough. Non-stick coating is essential — caramelized sugar bonds aggressively to uncoated surfaces. One important maintenance tip from commercial producers: clean the waffle iron while it's still hot, because hardened caramelized sugar becomes nearly impossible to remove once cooled.
The croffle's waffle-grid surface creates natural wells for toppings, while the rolled croissant shape allows fillings to be tucked inside before pressing. This dual capacity has produced an enormous range of sweet and savory variations across different markets.
Sweet fillings placed inside the dough before pressing include Nutella (the single most popular worldwide), chocolate chips, sweetened cream cheese, jam, dulce de leche, Biscoff spread, and peanut butter with banana. Korean-specific fillings reflect the country's dessert traditions: red bean paste (often in the classic "ang butter" combination with butter), sweet potato paste, and injeolmi (rice cake coated in roasted soybean powder). Japanese variations lean toward matcha milk jam and mochi.
Savory fillings turn the croffle into a meal: ham and cheese, scrambled eggs and bacon, pepperoni and mozzarella for a pizza-style croffle, and smoked salmon with cream cheese. Seoul's Saddler Haus built its reputation on a corn and cheese croffle that became one of the city's most sought-after items.
Post-cooking toppings range from the simple to the extravagant. The quintessential Korean café pairing is a warm croffle with a scoop of ice cream — vanilla, strawberry, matcha, or pistachio — finished with a dusting of cinnamon powder. Other popular sweet toppings include whipped cream, fresh berries, maple syrup, chocolate drizzle, honey, crushed Oreos, and powdered sugar. Savory toppings can transform a croffle into a brunch dish: fried eggs with runny yolks, crispy bacon, avocado, sautéed mushrooms, and hollandaise sauce for a "croffle Benedict."
Some of the most creative variations push into fusion territory:
Aufglet in Geumho-dong holds historical significance as Korea's first croffle café, now expanded to three locations (Geumho, Hannam, Yeonnam), serving its signature croffle with homemade ice cream and cinnamon powder for approximately 9,000 KRW. Saddler Haus on Garosu-gil has achieved near-legendary status for its palm-sized croffles, particularly the cheese-corn variety limited to 60 per day at 4,900–5,800 KRW. Fair in Hapjeong draws visitors for its distinctive brown cheese croffle. Cafe Knotted, Korea's iconic cream donut brand with over 40 locations, offers a Strawberry Milk Croffle for 4,200 KRW. Verona in Euljiro serves a striking red velvet croffle — ice cream dusted with red velvet powder to resemble tiramisu — in a stained-glass-windowed space. Other notable Seoul spots include Another Room in Yeonnam-dong, O8 in Haebangchon (with a Namsan rooftop view), and Better Day Café in Hongdae.
Croffle House in Flushing, Queens is arguably America's most prominent croffle destination. Co-founded by William Ham and pastry chef Kooksu Kim (formerly of Tous Les Jours), who discovered croffles during a 2019 Seoul trip, it offers over a dozen varieties — Mont Blanc, basil pesto, dalgona, ang butter, purple yam — mostly priced under $7, with over 1,200 photos on Yelp. In LA, Heuk Hwa Dang in Koreatown (a Korean franchise also present in Malaysia and Japan) serves both sweet and savory croffles including a pepperoni variation. SMOOVE in the Bay Area specializes in croffle-and-ice-cream pairings, while Creamistry launched croffle creations across its California franchise in 2022, pairing them with liquid nitrogen ice cream.
In Singapore, Crolo (by Swee Heng Bakery) positions itself as the country's first croffle specialty store, Tiong Bahru Bakery added croffles to its all-day menu (including a breakfast croffle with bacon and Portobello mushroom), and Walking on Sunshine in Orchard Central offers an all-you-can-eat kroffle buffet. In Japan, The Matcha Tokyo offers matcha milk jam croffles across multiple locations, while Tokyo's Shin Okubo district (the city's Koreatown) hosts numerous Korean-style croffle vendors. In Hong Kong, Kroffle in Yuen Long created croffle burgers — pepperoni-stuffed croffles with scrambled egg, and a lobster version with avocado.
The croffle's staying power has exceeded most predictions. When Eater NY published its landmark August 2021 article — "The Croffle Lands in NYC, Seeking Cronut-Level Fame" by Caroline Shin — the comparison to Dominique Ansel's 2013 Cronut was both obvious and instructive. The Cronut required professional technique and spawned enormous lines at a single bakery; the croffle democratized the hybrid-pastry concept by being reproducible in any kitchen with a $20 waffle iron and a tube of frozen croissants. This accessibility proved to be its greatest competitive advantage.
Media coverage has been extensive and sustained. Mental Floss called it "the Croissant-Waffle Crossbreed Hoping to Be the New Cronut." Mashed predicted it would be "Your 2022 Breakfast TikTok Obsession." The South China Morning Post and allkpop covered its K-culture dimensions. Harper's Bazaar India profiled "The Croffle Guys" brand in 2025. The croffle even penetrated Korean entertainment: on MBC's King of Mask Singer in March 2024, a contestant performed under the stage name "Croffle" — a sign of how deeply the word has entered Korean pop culture. In May 2024, actor Jung Hae In sent BLACKPINK's Jisoo a croffle support truck during filming of K-drama Influenza.
The croffle's cultural significance operates on two levels. In South Korea, it has transcended trend status entirely, joining dalgona coffee and bingsu as a permanent fixture of the country's globally influential café culture. Commercial equipment manufacturers like Belgium's Ampi now sell dedicated croffle-specific waffle makers, signaling industry recognition of the category's permanence. Internationally, the croffle represents the growing influence of Korean food culture — arriving not through traditional restaurant channels but through the same social media ecosystem that carries K-pop, K-drama, and Korean beauty trends. French traditionalists may bristle (the South China Morning Post acknowledged the idea "might sound outrageous, even offensive" to purists), but the croffle's combination of French pastry technique, Korean café aesthetics, and internet-age accessibility has made it something rare in the food world: a viral trend that became a lasting category.
The croffle's journey from a 2015 cooking video to a global pastry category illustrates how food innovation now travels. The concept was born in the West but perfected and amplified by South Korea's café culture and social media ecosystem. Its genius lies in simplicity — laminated butter dough meets hot iron, sugar becomes glass — and its durability comes from infinite adaptability, whether filled with red bean paste in Seoul, topped with snow crab mentaiko in Singapore, or served as a breakfast sandwich in Queens. The croffle is not the new Cronut. It may be something more interesting: a hybrid pastry that belongs to no single creator, no single country, and no single moment, but continues to evolve wherever someone has a waffle iron and a sense of possibility.
