The Newest Dr Pepper Drink Is ‘Not a Want but a Need,’ According to Fans

When the summer heat hits, nothing gets me through the afternoon quite like a trip to the drive-thru for a refreshing treat. The hardest decision, though, is choosing between a crispy McDonald’s Diet Coke and a frozen fast food creation, such as a Wendy’s Frosty.

Luckily, a popular fast food chain has a brand-new offering that is perfect for the days when I simply can’t decide between an ice-cold soda and a frozen sweet treat. This all-new menu option combines my two favorites—soda and ice cream—into a new blended beverage fans won’t find anywhere else.

Whataburger’s New Dr Pepper Blackberry Shake

Whataburger is releasing a brand new Dr Pepper Blackberry Shake, a delightfully refreshing mash-up that brings together the legendary 23 unique flavors of Dr Pepper with Whataburger’s signature milkshakes. The perfect mash-up of two Texas icons, Whataburger’s new soda-inspired shake is a smooth, refreshing, and seriously crave-worthy treat to get you through the hottest of days.

After successful iterations like Strawberries & Cream, Creamy Coconut, and even Vanilla Float, fans of the soda brand were thrilled when the all-new Dr Pepper Blackberry soda hit shelves in early 2025. Featuring a blend of signature Dr Pepper spice and juicy blackberry taste, the fruity new flavor was an instant hit. Now, Whataburger is giving the fan-favorite Dr Pepper flavor a cool and creamy spin just in time for the tail end of summer.

Available starting Aug. 5, this new menu item features Whataburger’s signature Vanilla Shake base swirled with Dr Pepper, plus a touch of blackberry flavor. The smooth, indulgent treat—which is a follow-up to Whataburger’s original Dr Pepper Shake from 2024—is the ideal summer sipper. Fans on social media are already hailing it “Not a want but a need.”

If you need an entrée to pair with your Dr Pepper Blackberry Shake, Whataburger is celebrating its 75th birthday with 75-cent burgers for one day only. On Aug. 8, from 11 a.m. to 8 p.m. local time, Whataburger Rewards members can score a 75-cent burger by ordering online or through the chain’s app.

Whether you’re hitting the drive-thru or stopping in for a discounted burger, Dr Pepper Blackberry Shake is the perfect way to cool off. But don’t wait too long—the shake is only here for a limited time.
