The launch comes on the heels of a co-branded online experience debut.

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

The cookie chain is also bringing back its popular Pumpkin Spice flavor.

The chain is best known as the creator of the Original Cookie Cake.

The Lemon Cookie is available for a limited time, June 17 through August 11 at participating locations.

Guests can indulge in this new flavor in the form of a cookie, a scoop of ice cream or a shake from November 6 through December 31.

In celebration of the upcoming release of its new movie, Glisten and the Merry Mission, Build-A-Bear Workshop is partnering with Great American Cookies on the Glisten and the Merry Mission Cookie Cake.

The three organizations will join forces to honor Neonatal Intensive Care Unit (NICU) patients, their families and the healthcare professionals caring for them.

Since its inception in 1977, the chain has expanded to 31 states and five countries around the world.
