I have this exact recipe that I got from the lady I used to babysit for when I was 13 (I'm 40 now...yikes). It's only different in the way that the marshmallows are not added to the batter. I suppose it has morphed like tons of other recipes...but adding the marshmallows to the batter makes it a lot more gooey (although it is called "mud" pie). For this recipe, in my opinion, it works better if you put the marshmallows on top after it's baked and cook it for 2 more minutes until the marshmallows melt. Then let it cool and frost with chocolate frosting and sprinkle with nuts when the frosting is soft.

Eeeyikes! This recipe is waaaay too sweet. 2 cups of sugar AND a pound of powdered sugar AND marshmallows! I took these brownies to a gathering and was embarrassed as it wasn't a hit. If I ever make this again, I'm using 1/2 the sugar!!

If you need a chocolate fix, this is it! There is more sugar than needed in this recipe. I cut it down to 1-1/2 cups for the brownie (the flour/sugar ratio should be the same). Instead of mixing the marshmallows into the batter I just scattered about 1 cup of them on top and then baked as directed. Don't add 4 cups of confectioners' sugar to the frosting! I used a generous 2 cups and it was plenty sweet. These were a huge hit in my house.

Wow!! Very rich, and very good! My family has had this recipe for years. The only difference is that we cover the brownies with the marshmallows after they've baked (as one reviewer suggested), so that they have their own layer. Very pretty when cut and served! Thanks for the recipe!

These are dangerously delicious! I made the brownie with 1 & 1/2 cups of sugar instead of 2 cups and made 1/2 the frosting and they were still perfect for flavor. They are a little bit messy to serve but the taste is well worth it!

These are deliciously sinful! The recipe comments indicate they are sweet, so I don't understand the surprise of the critical rater. Couldn't you figure out from the list of ingredients before you made these that they'd be really SWEET??????

I'm not allowed to make any other desserts... This one is in very high demand. I've made it 4-5 times already and it actually turns out a little different each time....

This dish was devoured by my health conscious sister-in-law and her boyfriend before and after they hit the slopes. It had such an impact that they even dream about them! I omitted the nuts, and they were just as good.
