With the rise of dirty sodas, drinkers are after beverages that are both fizzy and creamy, and Portillo’s teamed up with Dr Pepper to deliver with a brand-new Dr Pepper Shake and Dr Pepper Cake Shake. Available for a limited time, the rich and creamy Dr Pepper Shake combines the signature soda with vanilla shake mix, while the Dr Pepper Cake Shake blends a whole slice of Portillo’s famous chocolate cake straight into the shake.
The cake-infused shake mixed with all 23 signature flavors of Dr Pepper builds on the success of Portillo’s original Chocolate Cake Shake, which started out as a fun experiment turned into a favorite menu item. Now, the Dr Pepper Cake Shake offers a refreshing seasonal twist on the recipe, and Denise Lauer, Chief Marketing Officer of Portillo’s, says "If summer had an official milkshake, this is it."
