This recipe is from Gluten Free on a Shoestring. They are super quick and easy to make. By now you know they are made with black beans, but the rest is similar to a classic brownie recipe: eggs, vanilla, neutral oil (I used grapeseed), 2 tbsp of coffee (yes! I used decaf though), cocoa powder, baking soda, brown sugar and chocolate chips.
I followed the recipe exactly and we couldn’t taste the coffee or the black beans (trust me, my kids would tell me). As an aside, I have seen several black bean brownie recipes call for coffee so I believe it must help mask any bean flavor. Whatever the chemistry behind it, these brownies are some of the best we’ve made!
