Black Bean Brownies Recipe: Preheat oven to 350 F. Combine all ingredients except chips in a good food processor, and blend until completely smooth. Really blend well. (A blender can work if you absolutely must, but the texture—and even the taste—will be much better in a food processor. I use this food processor.) Stir in the chips, then pour into a greased 8x8 pan. Optional: sprinkle extra chocolate chips over the top. Cook the black bean brownies 15-18 minutes, then let cool at least 10 minutes before trying to cut. If they still look a bit undercooked, you can place them in the fridge overnight and they will magically firm up! Makes 9-12 brownies. If you make this recipe, don't forget to leave a review! The trick with these: serve them first, and then reveal the secret ingredient. In all the times I’ve served bean desserts, not one single person who didn’t know beforehand has ever guessed!View Black Bean Brownies Nutrition Facts
