The only white chocolate bar that has successfully managed to find a niche in mainstream candy aisles is Hershey’s Cookies ‘n’ Creme. Yes, I know there are other products out there like Zero, but they are very regional in distribution.
I am not so sure what makes the Cookies ‘n’ Creme bar all that appealing to the masses, since Americans tend to dislike white chocolate, but for some reason, the adding of cookie pieces (and smartly never advertising itself as white chocolate) has allowed this confection to achieve great success.
The candy debuted in 1994, capitalizing on the cookies and cream flavor craze that began in the eighties when the flavor first materialized in ice cream form.
