"After watching Giada's video, I followed her instruction exactly- using dark chocolate just as she did.

First of all, I let the tart rest for an hour after leaving the oven. The consistency was perfect, but the tart filling was EXTREMELY sweet. For those reviewers who said this tart didn't taste like Nutella, for me, it did. It was as if I was eating a much sweeter version of Nutella- and don't get my wrong, I love that chocolate hazelnut spread, but not an entire tart of it. It was just much much much too sweet for me and my friends. They could only get through a couple of bites before having to put their forks down- just way too sweet for everyone. I would never make this again...
