Broadway Brownie Bars

This is a wonderful brownie bar! Don't let the steps discourage you, it doesn't take long to make and boy are they worth it. The recipe calls for serving them chilled. We like them about 30 minutes out of the oven. There is nothing like melty marshmallow on top of chocolate. I left the nuts out, because of my children's preference. They would taste great either way. From Southern Living, March 1997.
