I am not usually this domestic, but these brownies are so effing amazing.
Disregard the whole "jelly roll pan" thing if you don't have one. Mix it all together, pour it in whatever pan you have, and then make the fudgy goodness to pour over the top. Stick it in the fridge for a while until the icing hardens, and you will have achieved nirvana.
If you use the new Hershey's Dark Cocoa, I guarantee an involuntary physical reaction (the good kind) upon biting into them.
(Note: This is not aphotograph of my actual brownies. It did not occur to me to serve them on a plate garnished with both white and dark chocolate chips, raspberries, and with a festive red tablecloth and gold mug of what I can only assume is beef gravy. )
I served them over the sink, so as not to get the crumbs all over the couch. Because I am genteel.
