Mine turned out ok, but I followed the whole recipe (well, pretty close, since I don't have any scales in the kitchen and had to get as close as I could with a measuring cup). I also had to bake it in a brownie pan since I didn't have a cake tin, and maybe its a coincidence, but it came out tasting like chocolate orange brownies, pretty thick. It was nice when it was warm with just icing sugar and pieces of chocolate orange on top, but once it cooled down, it was a bit hard around the edges and kind of stodgy.
Oh well, it's the thought that counts, as they say!!!
I guess DH liked it, but he only had one piece and never ate any of the rest of it, I ate a bit the following day, and ended up throwing the rest away. And my two-year-old stepson didn't like it at all, which is sad since he loves chocolate.
