Jack in the Box is going with blackberry as the temperatures rise with the onset of summer. For a limited-time, Blackberry is being added to Jack's line up of real ice cream milkshakes.
The new Blackberry Shake features real ice cream and blackberry-flavored syrup plus whipped topping and a Maraschino cherry on top.
It is available served in a 16-ounce or 24-ounce cup for $2.69 and $3.19 respectively (may vary).
