Black Bean Brownies...bleh

A year ago we tried a black bean brownie recipe that we found online. They were awful! It could be that we substituted something that didn't work out. They were gooey...not in the good way. So many bloggers were singing odes to black bean brownies, but I was no longer interested.

We've been trying out different recipes in The Vegan Slow Cooker. Low and behold, a recipe for black bean brownies! We decided that it was worth a shot and made them. What did I discover? Nothing spectacular. These are protein-dense with a dominant banana flavor. The texture is nothing delightful. I'd much rather make a loaf of banana bread!

What about you? Has anyone had any success with a black bean recipe? (Horror stories welcome too!)
