In June 2015, Wayback Burgers asked guests to develop their own milkshake concoctions. After receiving thousands of exciting and inventive entries, the flavors were narrowed down to just three:
- Bacon and Snickers®;
- Chocolate, Banana & Peanut Butter; and
- Chocolate, Peanut Butter, Bacon and Sriracha.
The public was then asked to vote on the flavor that they would most like to enjoy. The winner by a landslide with 73% of the votes was Chocolate, Banana and Peanut Butter. This winning combination will be made with WOWBUTTER®, which is a nut -free alternative to Peanut Butter, and tastes just as awesome. The Chocolate Banana WOWBUTTER® milkshake will be available starting in January 2016 for a limited time.
