mmmmmmm, some of my favorite cookies. I always make them with peanut butter, and i like the salt/peanutty taste it adds. We renamed them Poop Cookies, for obvious reasons. It fits much better than No Bake, I think. There are a lot of different recipes, but they all seem to have cocoa, sugar, milk, butter, oats(quick oats work best), vanilla, and peanut butter. Here's one I use:
1/2 c. milk
2 c. sugar
1/2 c. butter
bring to boil and continue to boil for exactly 3 minutes.
3 c. oats(quick)
1/2 c. peanut butter(use some w/ a little salt)
1 t. vanilla
have all of this mixed together thoroughly, then when cocoa mixture is ready, pour it over this. let sit for about 30 sec., then stir and scoop cookies out onto wax paper or whatever surface you like.
It's hard to get the texture right, sometimes they can be gritty when they cool. I hear the 3 minute boil makes them come out right, although its been a while since I've made them so I can't remember.
If you look up 'no bake cookies' on recipezaar.com there are several different versions.
