I made this for my BIL. I personally do not like chocolate, but reportedly it was quite good. It is basically a cake-style brownie batter baked up in a cake pan (9 x 5 x 3") instead of a regular 8 x 8 pan, and the cooking time has been adjusted accordingly.
This was wonderful - not as sweet and sticky as a brownie but a lot of chocolate flavor. Very easy to make, too!
