Oreo-Inspired Deep Dark Brownies

The secret to success* with these lies in using the cocoa with the highest percentage of cacao you can find. Essentially, the darkest chocolate powder. This makes the brownies almost black in appearance and extremely rich in taste.

* note: I define success by how much batter gets eaten before anything actually gets baked. In this case, it was a lot.

(by the way, these are under 150 calories!)
