In the 102 years that Nabisco has been making Oreos, there really is no need to change their delectable recipe (Except for Double Stuf, those rule). However in recent years they roll out a new flavor every so often to generate interest. Previous efforts have included candy corn, birthday cake and watermelon. In their most recent attempt to take over the cookie world, Oreos has launched two new varieties, cookie dough and “marshmallow crispy,” a rip-off of the infamous Rice Krispies Treat, but Kellogg’s owns the rights. The fascinating new flavors debut on Feb. 3 and are expected to be available for six to eight weeks.
