To celebrate St. Patrick’s Day, Crumbl is refreshing its rotating menu with a festive lineup of seasonal flavors and consumer-favorite classics, the brand says. As Crumbl continues to aim to redefine the dessert category, the flavors—which will be available starting March 15—focus on party-ready treats and brand collaborations.

The feature of the week includes:

• St. Patrick’s Celebration Cake Cookie: A fluffy cake batter cookie with cake batter cream cheese frosting and a splash of green sprinkles.

The rotating lineup includes:

• Key Lime Pie Cookie: Pie-inspired layers of tangy lime, airy cream, and buttery graham. A refreshing chilled graham cookie layered with zesty lime filling, then topped with whipped cream, graham cracker crumbs, and a fresh lime wedge.
• Cereal Milk Cookie: Soft sugar cookie, milky glaze, fruity cereal crunch. A soft cereal-inspired sugar cookie brushed with a milky glaze and topped with vibrant, fruity cereal.
• Special Collaborations: Crumbl will feature two additional flavors created in collaboration with Lucky Charms and Andes Mints.

The classics, also available that week:

• Pink Sugar Cookie: Classic almond sugar cookie topped with a pink swoop of real almond frosting.
• Cookies & Cream Cookie: A warm chocolate cookie mixed with cookies and cream pieces, topped with smooth vanilla cream cheese frosting, and sprinkled with more cookies and cream pieces.
