Each week Rosanna Pansino cooks up a new geeky baking tutorial. Her channel's 6 million subscribers are eating it up, and it's starting to make her a lot of dough. "I started creating content for fun," Pansino told CNBC's On the Money in an interview. "I really wanted a creative outlet and it wasn't about business at all."
Pansino is one of YouTube's most successful creators, earning $2.5 million in pre-tax revenue last year according to Forbes.
She's not the only one. Other YouTube millionairesinclude video game commentator Felix Kjellberg, known by his screen name PewDiePie, who earned a cool $12 million last year. Meanwhile, the comedic duo behind Smosh earned $8.5 million.
