When we used to have a Chart House in our area my husband loved their bread. I may have a recipe somewhere that someone got for me, I just have to find it, which may take days.
I remember it being very dark and slightly sweet which is maybe the molasses?
I did a google and there are a ton of recipes out there.
Did you have it at a Chart House?
