Portillo's Unveils Brand-New Oreo Cake Shake and Limited $1 Halloween Deal
The newly unveiled Oreo cake shake avoids overcomplicating an established format. Rather than reinventing the mixer base, the kitchen team takes a slice of chocolate cake baked with crushed Oreo cookies, layers it with classic cookies-and-cream frosting, and spins it with vanilla ice cream and whole milk. Bits of wafer cookie cut through the thick fudge frosting, providing a contrasting textural crunch that the traditional chocolate cake shake lacks.
For guests who prefer a fork over an extra-wide straw, the restaurant is also selling the Oreo cake slice on its own. Packaged in the brand’s familiar triangular bakery containers, the single slice serves as a standalone dessert or a take-home item. The addition stands alongside previous seasonal Portillos items, such as the lemon cake shake and salted caramel variations, but leverages the cross-promotional clout of a globally recognized Nabisco trademark to drive curiosity at the counter.
