This is a rocky road brownie from Mike's Pastry in the North End. The place is world famous, apparently, and an old friend suggested it via facebook while I was there. The place was crazy, with tons of people waiting to be served, and without a number system, so pandemonium ensued. It was worth the wait to have this piece of decadence.
The cakey brownie was covered in a fudge-like frosting, with nuts and marshmallows on top.
