Although it was popularized in South Korea, Irish pastry chef and TV show host, Louise Lennox, is sometimes credited with inventing the pastry. Lennox collaborated with bakery chain Cuisine de France at a 2017 pop-up called La Petite Boulangerie in
Dublin, Ireland where the croffle was the
pièce de résistance. In November 2018, the café Aufglet debuted the croffle in
Seoul. By early 2019, the croffle's popularity spread throughout the city, being served at various cafes and street food vendors. In 2020, the
COVID-19 pandemic led to a dramatic increase in popularity. The ingredients were accessible and the preparation was relatively easy, so people staying at home started making croffles and posting pictures of them on social media. Some estimates suggest that waffle iron sales increased 300 percent from May 2019 to 2020. On 7 April 2020, South Korean singer and actress,
Kang Min-kyung, posted on Instagram that the croffle was "really, so, so, so tasty". Later in 2020, the croffle's popularity reached the United States, appearing in
Flushing, Queens and
Los Angeles Koreatown. It continued to spread globally, and started being served in pastry shops in Singapore, Thailand, Hong Kong, Canada, and Indonesia. Up to 2021, it continued to be popular on social media platforms like
TikTok and YouTube. == Preparation ==
