Ok. So this brownie is more like "not-so-naughty" brownie. It's made with black beans. It isn't my recipe but I have tweaked it in some ways. First off, no you cannot taste the black beans. Two, it is not as sweet but it is yummy, dense and fudgy. And full of protein.
1 box store bought brownie mix or your favorite homemade recipe
1 14oz can black beans and juice, pureed (blender or food processor)
1 egg, beaten
1 tablespoon vegetable oil
1 teaspoon vanilla
Mix the black beans, egg, oil and vanilla. Add to brownie mix and bake according to directions on box.
If you are making it from your own homemade brownie recipe instead of the box, cut down on the oil and eggs used. This recipe is not very finicky as far as baking goes so if you add a little more or less it shouldn't effect the outcome.
HINT: If you want it a little bit more dessert-ish, combine 3/4 cup of light creamcheese, 1 1/2 cups icing sugar, 1 teaspoon of vanilla and 4 tablespoons of cocoa powder and beat until smooth. Spread over brownies.
