I'm always thinking about ways to incorporate beans into a sweet dish and stumbled upon this recipe at veganfitness.net for black bean brownies. I modified the recipe to make them GF and easier to make. Luckily Melinda's GF brownie mix is vegan. All I needed to add was margarine, which I made myself, and a tin of black beans.
I basically followed the packet instructions and used mashed black beans as a binder instead of no-egg.
My margarine recipe is a blend of several I found on the net.
Vegan margarine recipe
1 part water (I used 1/4 cup)
2 parts oil (I used 1/2 cup)
Enough ground soy lecithin to emulsify the mix (About 2 tablespoons)
Blend the oil and water and add lecithin. Continue blending until it resembles a soft margarine. Add some turmeric if you want to make it yellow.
I made these for the "super duper vegan picnic" that was held last weekend and everyone who had a taste was a fan. They probably would have thought less of me if they knew how easy it was.
