Nutella Gooey Butter Cake

So do you remember that post I wrote long ago called 'Dear South, What the Heck is Gooey Butter Cake'? I was so baking naive way back in April 2010 wasn't I? Well anyway, I found an upgrade. And while I'm a little upset to part with the original recipe because it was SO good, I had to venture and try this one I found using Nutella. If it involves Nutella, it's gotta be good. The original recipe came from Let's Dish. I kept everything the same except I didn't use Devil's Food Cake for the crust. I just used plain yellow cake mix. I thought the chocolate crust and the Nutella center might be a little too rich for me. Overall, it turned out really good but I think I actually like the original better. I don't know, what do you think?
