I'm surprised no one has answered this. Ahh....Oreo's yum! I don't eat sugar anymore but when I did Oreo's were a splurg. Love them. Anyways , yep they turn your output black. Chocolate doesn't do that to me so they must have something else to give them that really dark color. Maybe some food coloring? Anyway if you want to be sure wait a few days then eat the same amount and see if it does it again and report back on you're findings. Pretty sure tho their the culprit.
