I had to try this, "black bean brownies?!" They were so worth it, and easy to put together. The texture was soft and delicate. I added cinnamon, as well, as I like that flavor with my chocolate and it was just lovely. I couldn't wait for them to cool completely (as the recipe suggests) before trying them, so they tore a bit around the nuts, but totally worth it!
These were better than expected, but they definitely couldn't be eaten alone. They were great with some low-fat vanilla ice cream. They reminded me a lot of No-Pudge Fudge brownies.
