Insomnia Cookies, which was founded on a university campus, is welcoming students back to the fall semester by throwing its first-ever global PJ Party. On Tuesday, September 19, fans near each of the bakery chain’s 245+ bakeries globally, including its newest locations in Canada and the UK, are invited to head to their local store dressed in their favorite pajamas for the party.

Those who show up to the late-night cookie celebration at 9 pm local time wearing their PJs will receive 1 free classic cookie, no purchase necessary. Additionally, cookie lovers can purchase $15 12-Packs in-store and online all day and late into the night. Each store will also be offering giveaways, exclusive swag and other sweet surprises during the event.

Insomnia Cookies will be unveiling a new CAP’N CRUNCH BERRIES’N Milk Filled Deluxe cookie the night of the party, which will be available for a limited time only. The exclusive cookie is a brown sugar dough mixed with CAP’N CRUNCH’S CRUNCH BERRIES cereal and strawberry bits, and filled with a cereal milk buttercream.

Fans wearing their favorite PJs to their local celebration can tag @insomniacookies on social with #PJP23 for a chance to win free cookies for a year. More details will be available the day of the event on Insomnia’s Instagram page and TikTok.
