Volcano Cake

I was watching food network today, the Semi-homemade show. She made a volcano cake. It was so cool! It even had smoke coming out of it. Here's the link. I definately want to make that someday. http://www.foodnetwork.com/recipes/semi-homemade-cooking-with-sandra-lee/volcano-cake-recipe/index.html
It looked cooler on TV than the pic you'll find on the website.
