Mrrzy, regarding carob I was thinking more along the lines of not-chocolate brownies using carob powder. I don't like the carob bars pretending to be chocolate bars. It doesn't work for me.

I found a recipe using my fave cake ingredient. I make a lovely gluten free orange and almond cake using processed almonds or almond meal instead of flour. I'm not gluten free but I used to take it to work because one of my friends is gluten free. The orange flavour is a real orange boiled and then processed in the food processor - everything but the seeds. You can also have orange syrup made from fresh orange juice poured over the cake when it is cooked. Or different fruit can be used in the cake instead of an orange.

I found the recipe to make chocolate brownies or even orange choc brownies and it was super-yum. It would work with carob, but maybe some cocoa powder as well to provide the chocolate hit.
