Muffin from Starbucks along the Florida Turnpike

I ate a chocolate muffin from the Starbucks along the Florida Turnpike in the Port St Lucie/Ft Pierce Rest Area. I'm not a big fan of coffee drinks so I don't get drinks from Starbucks often, but I did like this muffin. It was chocolaty, but the chocolate wasn't overpowering. Technically, I would say it actually tasted much more like a brownie than a muffin...
