Available now, the Blackberry Shake is a frosty delight of real vanilla ice cream blended with pieces of real blackberries served with creamy whipped topping and a maraschino cherry.

“While strawberry and blueberry shakes are fairly common, blackberry is a unique flavor that’s growing in popularity,” said Teka O’Rourke, director of menu marketing and promotions for Jack in the Box. “Our new Blackberry Shake has a refreshing fruit flavor our guests will find very appealing as the days grow longer and warmer.”

Jack’s new Blackberry Shake is available in 16- and 24-ounce servings for the suggested prices, excluding tax, of $2.49 and $2.99, respectively, at all participating Jack in the Box restaurants.
