I had tried other black bean brownie recipes before, but they had more of a cake-like consistency and just tasted "off." I admit I was skeptical when I saw the title of "fudgy", but these were fantastic. Mine needed only 35 minutes in the oven, and they were very moist and fudgy. I used honey instead of sugar and just eyeballed the amount. I was worried at first when the batter seemed very runny, but I couldn't have asked for a better end product. These are going on my recipe short-list for sure!
I also appreciate the tip about cooking beans in a slow cooker. I try to avoid buying items in cans since I don't trust can linings, so I bought a bunch of dry beans. I cooked them on high, and they were already splitting after 4 hours (even without presoaking), but it was perfect for this recipe, and I liked not having to man the oven to cook the beans.
