Oreo has been releasing unexpected flavors for years, and back in 2015, the world got a taste of Key Lime Pie Oreos. Though it was deemed a limited-edition flavor at the time, it seems that Oreo has brought it back two years later! This is either good news or bad news for you, depending on how you feel about the graham-flavored cookie with the green, Key-lime-pie-inspired creme filling. Junk-food-loving Instagram account Unwrapped Daily shared this photo of the Oreo cookies, which were spotted at stores including Winn-Dixie and Walmart. In case you've never tried them before, this person claimed, "They have a pretty good Key lime flavor and the cookie acts as the crust of the pie. The only downside is that the flavor is artificial tasting. I also don't think I'd rather have these over some other flavors. Decent overall and worth the hunt." If you'll take a Key Lime Pie Oreo over a homemade Key lime pie any day, be on the lookout for these cookies before they inevitably disappear from shelves again.
