Zisser continues to eat away at the chocolate, and completes the challenge in seven minutes and six seconds.
The YouTube star with a cult-like following said after completing the challenge she was happy with her time.
"I'm pretty stoked with that considering chocolate is really difficult to eat," she said.
"It was quite hard but i'm pretty stoked that I got through it that quickly without any liquid."
Zisser has also partaken in challenges such as the 100 cheese burger challenge, in which she managed to eat 45 in just under two hours and also ate 22 Big Macs in just under an hour.
