Chocolate chip cookie dough ice cream is a popular ice cream flavor in which unbaked chunks of chocolate chip cookie dough are embedded in vanilla flavored ice cream.
Chocolate chip cookie dough ice cream was said to have originated in 1984 at the first Ben & Jerry's "scoop shop" in Burlington, Vermont, from an anonymous suggestion on their flavor suggestion board.
[1] In 1991, Ben & Jerry's began selling pints of the flavor which quickly became popular with consumers.
By 1992, chocolate chip cookie dough accounted for 20 percent of the company's total ice cream sales, and other ice cream manufacturers such as Dreyer's and Mrs. Fields began making their own versions of the flavor.
They invented a technique for maintaining the chewy consistency of the cookie dough when frozen, which the founder described as a "technological breakthrough".
