Portillo’s Dr Pepper Shake and Dr Pepper Cake Shake launched on August 4, 2026, at participating U.S. restaurants. The limited-time desserts blend vanilla ice cream with Dr Pepper flavor, with the cake version adding Portillo’s chocolate cake through September.
Portillo’s launches two Dr Pepper desserts
Portillo’s launched the Dr Pepper Shake and Dr Pepper Cake Shake on Tuesday, August 4, 2026, adding two limited-time frozen desserts to its U.S. menu. The collaboration combines the restaurant chain’s vanilla shake with the distinctive flavor associated with Dr Pepper.
The products are available at participating Portillo’s restaurants through September while supplies last. The Portillo’s restaurant inside Dallas Fort Worth International Airport is excluded from the promotion.
Dr Pepper Shake blends vanilla and soda flavors
The standard Dr Pepper Shake combines Portillo’s creamy vanilla shake with Dr Pepper’s signature 23-flavor blend. The drink offers customers a frozen-dessert version of the soda’s recognizable flavor.
The launch expands Portillo’s selection of temporary and seasonal shakes while giving Dr Pepper fans another way to experience the beverage brand.
Chocolate cake creates a richer shake
The Dr Pepper Cake Shake starts with the same vanilla and Dr Pepper base but adds a slice of Portillo’s chocolate cake before blending. The addition creates a thicker dessert combining vanilla ice cream, soda flavor and chocolate cake.
Customers can choose the standard version or the cake shake depending on whether they want a simpler milkshake or a more substantial blended dessert.
Availability may vary by restaurant
Portillo’s plans to offer both shakes through September, although the company says they will remain available only while supplies last. Customers may need to confirm availability with their nearest participating restaurant before ordering.
The collaboration gives Portillo’s a seasonal menu attraction built around two recognizable products: Dr Pepper’s soft drink flavor and the restaurant chain’s chocolate cake.
