So anyway, these had neither black bean nor pumpkin, but spinach. I've been eating a lot of decadent dessert of late, so I thought I'd change it up for something with redeeming nutritional value, plus I had a bag of spinach I needed to use up. I went with this recipe instead of this one I'd been eyeing on Fit Sugar, due to its use of actual eggs.
I did make a few substitutions - I didn't have carrots so I just used spinach (and FYI, a 6 oz bag works out to about the required amount), I used whole eggs instead of just the whites because it seemed like a waste, and I did 1 tsp vanilla extract and 1 tsp almond extract. Also, I think I only baked them for 30ish minutes and they turned out fine.
Taste verdict? They're okay. Nothing without butter is going to really cut it for the decadence a brownie should have, but if you're looking for something chocolate-ish that's only 100-something calories a pop, you could do worse than these.
Will report back once I've attempted to feed these to coworkers.
