I use an 1/8 in a 9x9" pan (the usual size for boxed brownies). I dont do all that complicated butter crap; I just use an old fashioned morar and pestle. I always get waaaaaay to wasted on these things. I usual eat about five (of nine total), but when one of my girlfriends tried a single bite of it, they were stoned through dinner. They taste like brownies with dirt in them, though.
