Nana's Famous Fudge Brownie recipe, from The Food Charlatan. The most decadent fudge brownies with chocolate fudge frosting you will ever eat! These brownies are thick and chewy and not cakey in any way shape or form. They really do taste like fudge. My husband's grandma (Nana) is famous for this recipe! You can add walnuts if you like, or add them to half the pan. So rich!
