Key Lime Tea Cookies ($4)
OK, so Trader Joe's Key Lime Tea Cookies aren't exactly new: they were released in August 2015. But the cookies have a whole new look with updated packaging, and if you never picked up these cookies in the past, you're going to want to as soon as possible. The buttery shortbread cookies are just limey enough, and each is coated in the perfect amount of powdered sugar. We'd recommend grabbing these for a Trader Joe's picnic this Summer.
