Quick chocolate dessert

I found this quick recipe for "grownup poptarts" at the blog Little acorn. Had to try it. I would not call it a poptart. But I never had poptarts with chocolate ... maybe they do taste similar. The taste rather reminds me of the french pain au chocolate (no idea whether I spelled that right). It was really quick to make, however we liked it better completely cooled. (We ate the first batch while still warm and realized only later that they taste much better cold.)
