Smashburger is turning 8. As a way to celebrate, the better burger restaurant known for its smashed-to-order burgers is unveiling its newest addition to their premium Haagen-Dazs shake selections: a Birthday Cake Golden Oreo Shake made with cookies, available for a limited time only starting June 30. Hand-spun with Vanilla Haagen-Dazs ice cream, milk, and crushed birthday cake Golden Oreo cookies, this new shake is sure to satisfy all birthday cake flavor fanatics as it tastes like the perfect blend of birthday cake and frosting.

To celebrate Smashburger’s 8th Birthday on June 30, Smashfans are invited to indulge in a special offer of a free Birthday Cake Golden Oreo Shake for each Birthday Cake Golden Oreo Shake purchased.

“We are excited to introduce a new limited-edition shake in celebration of our 8th birthday that creates the flavor of two of America’s favorite desserts: cake and ice cream,” says Tom Ryan, founder and chief concept officer of Smashburger. “We always strive to have an innovative menu and enjoy experimenting with different flavors, so we wanted to take advantage of our birthday to create a limited-edition item with a flavor that is not only known to be popular, but is perfect for a celebration. We are thrilled to provide our Smashfans the opportunity to indulge in the new limited-edition Birthday Cake Golden Oreo Shake made with cookies.”

Available at all Smashburger locations nationwide through August 24, the Birthday Cake Golden Oreo Shake is the perfect addition to any Smashburger meal. Pair the shake with any juicy, smashed-to-order burger made with 100 percent certified Angus Beef, a grilled or crispy chicken sandwich, or premium salad entrée. Round out the meal with signature sides like seasoned fries with rosemary, olive oil, and garlic, haystack onions, or fried pickles. Whether you have a birthday to celebrate or not, the Birthday Cake Golden Oreo Shake can be enjoyed with a meal or on its own as a festive dessert.
