put the sugar and butter and let it sit while the butter softens. Then add the cocoa, vanilla and eggs.

Beat this mixture until mixed well, there should be no lumps of butter. Once this is mixed add the flour, I add 1/2 cup at a time. Mix again (I used a hand mixer).

Chop the walnuts and add at this time, mixing in with mixer.

Take your 9X13 pan and coat with oil, crisco whatever you like to use and dust with flour.

Spread mixture on pan and bake at 350 for 20 minutes.

Then pull out of oven and spread marshmallows on top, usually one entire bag, put back in oven and bake until marshmallows puff up, maybe 5 minutes or less depending on the (hotness of your oven). Do not over bake.

Let brownies cool entirely before frosting

NOTE: Aunt Mary always brings these to family parties and are a family favorite.
