Mississippi Mud Cake

This has been requested as 'birthday cake' for 2 years in a row from one of my sons, so I guess it must be good !
While the 'cake' is not too sweet, the frosting/marshmallow topping is uber sweet, so it balances out. Here's what you need:

I love it the next day best, not sure why.

Remove from oven and sprinkle with marshmallows over hot cake.
Immediately spread frosting over marshmallows on cake. Cool in pan on a wire rack.

Cut into squares to serve. (Chill before slicing for neater squares, but I've always skipped that part !)
