I made some black bean brownies tonight, but the recipe I have been meaning to try for a while now. I have a "Food" file on my desktop. These are not vegan, but are gluten-free. And so fudgy, yet light. I used turbinado sugar, no coffee, and coconut oil in place of canola. I think it could do with less sugar, they are a bit too sweet for me. Next, I will also try HWPG's recipe. I heart brownies.
