  1. Preheat oven to 350 degrees F (175 degrees C). Grease a 9x13 inch baking pan.
  2. In a large bowl, stir together the white sugar and cocoa. Mix in the melted butter until well blended. Beat in the eggs one at a time, then stir in 2 teaspoons vanilla. Combine the flour, baking powder and salt; stir into the chocolate mixture. Fold in walnuts. Spread evenly into the prepared pan.
  3. Bake for 30 minutes in the preheated oven, until the cake starts to pull away from the sides of the pan. Remove from the oven and cover with an even layer of miniature marshmallows. Return to the oven for about 2 to 3 minutes longer. Remove from the oven and allow to cool in the pan.
  4. In a small saucepan over medium heat, combine brown sugar, water and unsweetened chocolate. Bring to a boil and boil for 3 minutes. Stir in 1 tablespoon butter and 1 teaspoon vanilla until well blended. Mix in the confectioners' sugar until smooth. Spread over the marshmallow layer. Allow frosting to set before cutting into bars.

These are great!! With a cup of butter I don't see how the other reviewers thought they were dry. Anyway, it helps to make sure the marshmallow layer is completely cool before you spread on y...

I really shouldn't review this since I made so many mods. But, I just used a box of low fat brownies mix and baked according to directions. Then added mallows. Made fudge frosting with 1/2 c....

My grandmother used to make these, and I was thrilled to find the recipe to look and taste the exact same! I followed it exactly, but doubled the frosting as one reviewed suggested. They turne...

These were not the marshmallow bars we thought we were getting. Be careful with the sauce to "spread over the melted marshmellows" Ours just smeared into one spot, removing the marshmellows from...

These were awesome. Only change I made was topped with 1/2 bag of marshmallows, not full. There isn't a need to change anything. Yum!

My kids loved this. I reduced baking time from 30 to 20 min and it was still a bit dry. If I made it again, I would use a moister brownie recipe for the bottom layer. Thanks for the recipe.

I made this on Saturday 03/12/2011. I loved them, my whole family loved them but, they were even better the next day after I left them in the refrigerator. So eat them warm eat them cold, do y...

I thought that this was way too sweet, particularly due to the frosting. Also, the bottom part is more like cake than fudge. Even after cooled, it was difficult to cut because the marshmallows w...

The ONLY thing I did not like about the frosting was the fact that I should have sifted the powder sugar and gotten rid of the tiny sugar clumps. My fault, this recipe ROCKS!
