Lots of people photograph their food and lots of people make DIY videos, but not that often does a clip of food being made actually go viral. This crock-pot lava cake is a notable exception, and deservedly so. It's a 30-second clip that nonetheless tells you exactly how to make it (more or less), and it can be done with box ingredients (and eggs and milk). It's going viral because it's irresistible-looking, not because it's a magic trick like this guy who peeled a watermelon. and is so tasty looking that you may storm out of your house after watching it when you realize you have no sweets.
