the most delicious food that you will ever eat. its addictive quality leaves you craving its chocolate smooth texture forever. it has a dense rich texture of milky chocolate with a thick rich chocolaty frosting with yummy sprinkles. although it is probably on of the most unhealthy things you could possibly ingest, it is completely. worth. it.

Bob: holy shit im going to puke, im never having a cosmic brownie again.
10 minutes later
