Yes. I eat expired granola bars all the time. I am a freak. Our grocery store has a discount aisle with expireds, and I will eat one and make sure it is okay before eating the rest. But cereal, granola, etc tends to be okay for longer than the legalistic shelf life. It's milk-based products you tend to want to eye closer.
My vote: try one, or just nibble if you're really nervous, then chow down on the rest if you survive.
If it tastes "off", then toss it, but it probably won't.
