While Japan is receiving graham cracker flavor KitKat Mini bars, Nestlé has released a key lime pie take on the classic KitKat bar. The Key Lime Pie flavor follows the Apple Pie take released last summer and the Pumpkin Pie flavor released in the fall. Undoubtedly not the first desired combination that comes to mind, the new option features the same crisp wafer layer coated in a bright green creme. The key lime pie flavored-creme can only be described as a creamy mix of tart sweetness.
