Late night cookie delivery chain Insomnia Cookies, often found near college campuses across the country, is celebrating the new college semester on Monday, September 13 with an all-day pajama party.

From 9 pm to 1 am that day at each of Insomnia Cookies’ 200+ locations throughout the country, guests can take advantage of free cookies, limited-time flavors, special deals, hidden codes, giveaways and more, as the brand’s PJ Party welcomes college students back to campus.

Debuting exclusively for the PJ Party is Insomnia’s newest Cereal N Milk Cookie straight from its experimental CookieLab.
