</div>CHICAGO, Aug. 13, 2026 <a href="https://www.globenewswire.com" target="_blank">(GLOBE NEWSWIRE)</a> -- From afternoon pick-me-ups to late-night cravings, summer is full of little moments that call for a treat. <a href="https://www.globenewswire.com/Tracker?data=oLklbgGxarZJd05kevjwdRLBN9LuUbweaQ6bcgS1Y07mcm2ie2mo_ZsJ5FSWKwM68q2kaCb7QKo45lODGO0ecg==" rel="nofollow" target="_blank" title="Portillo’s">Portillo’s</a> is making those moments even sweeter with the new Dr Pepper Shake and Cake Shake, created in collaboration with Dr Pepper. Now available for a limited time, the new Dr Pepper Shake blends Portillo's delicious vanilla shake with the one-of-a-kind flavor of Dr Pepper, creating a rich, sweet and creamy treat that's bold, nostalgic and downright delicious. Portillo’s guests can also order the Dr Pepper Shake as a cake shake, which blends a whole slice of Portillo’s famous chocolate cake with all 23 signature flavors of Dr Pepper into a next-level shake experience, available only at Portillo’s. “Some flavor combinations are just meant to be,” said Denise Lauer, Chief Marketing Officer of Portillo’s. “The iconic flavor of Dr Pepper paired with the indulgence of Portillo’s handcrafted shakes delivers a creamy, craveable treat that’s unlike anything else on our menu. If summer had an official milkshake, this is it.” The Dr Pepper Cake Shake builds on one of Portillo's most beloved menu items: the original Chocolate Cake Shake. What started as a creative way to blend the brand’s famous chocolate cake into a tasty shake quickly became a guest favorite and one of Portillo’s most iconic offerings. The new Dr Pepper Cake Shake takes that same legendary foundation and gives it a unique twist for the summer. “At Dr Pepper, we’re always looking for unexpected, delicious ways to bring our one-of-a-kind flavor to an indulgent new occasion,” said Jeff Tabor, Chief Customer Officer at Keurig Dr Pepper. “Blending our signature 23 flavors into Portillo’s beloved shakes felt both surprising and completely natural. The result is a rich, creamy treat that captures the bold personality of Dr Pepper in a way fans can only experience at Portillo’s.” The Dr Pepper Shake and Cake Shake are available now at participating Portillo’s restaurants nationwide for a limited time, while supplies last.
