I usually stay away from fast food baked goods as they're generally not tasty enough to waste money or calories on, but I was offered one for free about a month ago and was blown away by how delicious it was. It's probably the best chocolate chip cookie I've ever tasted that I didn't make myself. They use whole oats, both semi-sweet and milk chocolate chunks, and they're nice and soft even if you don't get one that came straight out of the oven. Most of the time they're still warm and gooey when you get your order, but I've found them to be just as good a few hours later when they're cool and less messy.
I've always liked Chick-fil-a so I wasn't surprised that they could pull off a good cookie if they put their mind into it, I was just surprised that it was *that* good. They're absolutely dangerous.
