They were surprisingly decent. I soaked my beans about 3-4 times to get all the slimy juice out of the can out and soaked them in a bowl of kefir on my radiator for about 2 hours before I made them. I got gassy the first time I ate them, but the second and third time I didn't get any gas. Sure, there is really no good reason to make these, but if for some reason you absolutely need to have brownies, these are probably a decent compromise. Considering the entire pan has something like 1,200 calories or so (just by me eyeing it up, I didn't do the math), you're not making a horribly fattening "dessert" and the fat that is present here is of top notch quality (cocoa fat and coconut fat).
I did not add any baking powder or baking soda, either. They were very dense. I also baked them for about 25 mins instead of 30 and truthfully, I should have gone less.
