“Crumbl has always been about creating moments of joy and connection through dessert,” said Sawyer Hemsley, Co-Founder of Crumbl. “As we celebrate our 9th birthday, we’re incredibly grateful for the fans, franchise partners and team members who have helped shape Crumbl into what it is today. This week’s menu is our way of celebrating with the people who made the last nine years possible.”

The limited-time Birthday Week lineup includes:

  • Pink Sugar Cookie Cake – A sugar cookie cake topped with a silky pink swoop of almond buttercream frosting.

  • Birthday Cake Cookie ft. OREO® – A thick cookie made with OREO® Cookie pieces, covered in cake batter cream cheese frosting and topped with more OREO® Cookie pieces and rainbow sprinkles.

  • Cake Batter Blondie Cookie – A smooth cake batter cookie packed with white drops and a delightful splash of rainbow sprinkles.

  • Strawberry Biscoff® Cookie – A Biscoff®-packed cookie from the melty center to the crunchy topping, finished with strawberry cream cheese frosting blended with house-made jam and a fresh strawberry slice.

  • Dubai-Style Chocolate Brownie – A soft fudgy brownie with a crunchy Kataifi and pistachio filling, topped with a layer of milk chocolate and drizzled with even more pistachio cream.

  • Chocolate Chip Cookie Cake Cookie – A brown sugar skillet cookie loaded with melty milk chocolate chips and rich semi-sweet chocolate chunks, topped with fudge frosting swirls and confetti sprinkles, inspired by a personal-sized cookie cake.

As part of the celebration, Crumbl will also offer a one-day 6-for-4 promotion on September 24, giving guests 6 desserts for the price of 4. The offer will be available through all Crumbl order flows, including in-store, the Crumbl app and crumbl.com, while supplies last. The promotion is not valid on third-party delivery orders.

“For nine years, our fans have shown up for each new flavor, each weekly menu and each reason to celebrate,” said Jason McGowan, Co-Founder of Crumbl. “Birthday Week is about sharing that celebration back with them, from new desserts to returning favorites to a one-day birthday gift made for sharing.”

Crumbl’s Birthday Week menu will be available at participating Crumbl locations from September 21 through September 26. The 6-for-4 promotion will be available September 24 only, while supplies last.
