Marvel Television’s highly anticipated Agatha All Along is now streaming on Disney+, and in celebration, Insomnia Cookies is conjuring up witchy new treats.

The chain is celebrating on Sunday, Sept. 29 with the bold flavors of its exclusive Magic Roast coffee and fan-favorite Dirty Chai Doughnut.

The fall favorite will be available for three days only, Friday through Sunday, September 20-22.

The new website functions as a dynamic co-branded platform that seamlessly integrates the two brands.

The Houston, Texas-based brand is celebrating its 88th birthday on Sept. 18 with a social giveaway of one dozen birthday prizes.

North America’s largest Halloween retailer is introducing exclusive costumes, and the two baking brands will be joining in on the fun with limited-time offerings.

The chain is getting into the seasonal spirit with three all-new doughnuts and a returning favorite that capture sweet and spiced flavors.

America's donut tour has formed a holiday in celebration of one of the season’s best treats and have created a website to help center the effort around.

The doughnut chain is looking to make this Friday the 13th a special one for customers.

On Tuesday, September 17, fans are invited to their local Insomnia store dressed in their favorite PJs to celebrate late into the night with free cookies, giveaways and temporary tattoos.
