Overview
- Portillo’s is selling a Dr Pepper–flavored milkshake at U.S. restaurants for a limited run through the end of September.
- The shake is made by blending Portillo’s vanilla ice cream with real Dr Pepper flavor as part of an official tie-up with Dr Pepper.
- Customers can upgrade the drink into a cake shake by adding a slice of Portillo’s chocolate cake that is blended into the milkshake.
- Published menu prices list a regular shake at $4.79 and a large at $5.89, with cake-shake prices shown as $6.69 and $5.59 respectively.
- The promotion excludes the Portillo’s location at Dallas/Fort Worth International Airport and follows a broader trend of short-term dessert collaborations used to drive visits and online buzz.
