Southern cakes: Mississippi Mud Cake

I am very slowly continuing to bake my way through this book . In our wiigue we are taking turns picking cakes we want to try out. This one was one of the ones Justin wanted to try: The Mississippi Mud Cake.
It's a rich almost brownie like cake with nuts, covered in melted marshmallows then topped with a chocolate icing. I am not a fan of marshmallows so I didn't try this one but everyone who did enjoyed it. I just wish I had a better picture of it.

Thanks for reading!
