DISCLAIMER: 4chan is not safe for work. It's probably not safe for home, either. I don't recommend you go to 4chan. You probably won't like what you find there. It will make your head hurt until you figure out what's going on (if you ever figure it out at all). 4chan is not for the faint of heart, nor the tender of spirit.
However... as I said, I go there sometimes, and find hidden gems of genius, which is why I'm posting about 4chan tonight. Some god-like epicure posted a recipe that I will have to try sometime when I'm craving something chocolaty:
Two Minute Brownies
4 tbsp flour
4 tbsp sugar
2 tbsp cocoa powder
2 tbsp water
2 tbsp oil
stick it all in a coffee mug
microwave for a minute and a half
Some brave souls tested it out and found it to be pretty good. Recommendations included mixing the stuff really well, adding a bit more sugar, adding chocolate chips, and whatever you do, don't use olive oil or the brownies will be full of fail.
If you try this, let me know how it turns out and I'll do the same.
