Available nationwide starting October 6, 2026, the limited-time lineup features three creations. The OREO Shake combines vanilla ice cream with crushed cookies, while the OREO Cake features a soft white cake layered with cookie pieces and frosting. The OREO Cake Shake blends the new cake directly into a vanilla milkshake, offering a different take on Portillo's signature Chocolate Cake Shake. The partnership allows Portillo's to refresh familiar menu favorites while attracting customers interested in seasonal desserts. To encourage purchases, Portillo's Perks members can enjoy a $1 slice of OREO Cake with a qualifying $5 purchase from October 12 through 18. The promotion also supports loyalty program engagement and encourages customers to explore the new offerings.
