The brand hosted a party on Tuesday night with a performance by Hailee Steinfeld at the Kellogg’s New York Café, which included a countdown to midnight.
There was also music from DJ Flipside, large cereal boxes suspended from the ceiling, a photo booth with cereal-themed party favouors, colorful confetti, and a "giant disco bowl" that lit up at midnight.
Those who didn’t make it to the party can try out the recipes at the café on Wednesday.
"Kellogg's NYC Café continues to spark creativity by encouraging people to reimagine what a bowl of cereal can be – and even the bowl is optional," said Aleta Chase, Kellogg's marketing director. "It made sense to celebrate this modern, inventive approach to how we think of food on National Cereal Day."
