They have spawned lines more than 100 people deep, inspired black-market scalpers on Craigslist and become one of New York City's edible tourist attractions.
But there is no testament to the deliciousness of Cronuts more convincing than this: On Friday, just after 6 a.m., a mysterious dead body within eyesight failed to persuade Cronut customers to give up their coveted places in line outside the beloved Dominique Ansel Bakery in SoHo.
"I didn't see anyone leave the line," Molly Young, 29, a city resident, told the New York Post. "It didn't put a dent in anyone's appetite."
Jessica Wright, 26, told the paper that she saw one customer briefly leave his place in line to tell bakery employees about "the dead guy" slouching on a sidewalk bench several dozen feet from the store.
"A guy in line was waiting for a Cronut and saw a body on the first bench," she said. "He brought it to the attention of a Dominique Ansel Bakery employee. She saw the dead guy and called 911. They came and pronounced him dead."
But when emergency responders arrived a few minutes later, nobody in line budged, CBS New York said.
The Cronut is considered a hybrid between a croissant and doughnut. The pastry debuted in 2013 and quickly became so popular that lines of hungry customers outside the bakery stretched halfway down the block, sometimes longer, the New York Times said.
"After the third day, we had a hundred people waiting outside," Cronut creator Dominique Ansel told the newspaper in 2015.
