  • Rich and Fudgy Texture: These vegan, oil-free black bean brownies are incredibly rich and fudgy, offering a satisfying dessert experience that feels indulgent without the guilt.
  • Packed with Plant-Based Protein: Made with black beans as the main ingredient, these brownies provide a protein boost, making them a healthier treat option that also supports a plant-based diet.
  • Free from Refined Oils and Added Fats: These brownies are made without any added oils or fats, making them a lighter, heart-healthy choice perfect for those looking to enjoy a dessert without the extra calories.
  • Simple and Wholesome Ingredients: Using wholesome ingredients like black beans, cocoa powder, and natural sweeteners, these brownies are both delicious and nutritious, catering to those who want a clean and simple dessert.

Ingredients you will need

Oat flour
  • Rolled oats- Adds a mild, nutty flavor and a tender texture while keeping the recipe gluten-free.
  • Black beans- Using black beans to make vegan brownies adds a rich, fudgy texture while providing a boost of plant-based protein and fiber. Black beans also help create a moist, dense consistency in the brownies, making them deliciously decadent without needing eggs, butter, or refined flour.
  • Cocoa powder- Gives the brownies a rich, intense chocolate flavor while keeping the recipe low in fat and calories. Cocoa powder also adds antioxidants and enhances the overall taste, creating a decadent, chocolatey treat that perfectly complements the fudgy texture of the black bean base.
  • Applesauce- Adds moisture and a natural sweetness without the need for added fats like oil or butter. It also helps bind the ingredients together, creating a soft, fudgy texture while keeping the brownies lower in calories and healthier overall.
  • Vegan chocolate chips- Look for dairy-free or vegan chocolate chips made with plant-based ingredients. Many brands offer chocolate chips that are free from milk or other animal products, ensuring your muffins remain 100% vegan. My favorite chips are these mini vegan chocolate chips.

How to make black bean brownies

The recipe card at the bottom of the page has the full list of ingredients with measurements and instructions.

STEP #1: Begin by placing 1 cup of oats into your blender or food processor and blend for less than a minute until they are nice and powdery to make oat flour. I have lots of other recipes that use oat flour as well.

STEP #2: Next, drain and rinse one can of cooked black beans, or use 1.5 cups of your own freshly cooked beans. I like to place my beans in a colander and run water over them to rinse well.

STEP #3: Add the beans and all other ingredients (EXCEPT the chocolate chips and walnuts) to your blender or food processor. Blend until nice and smooth, stopping to scrape down the sides as needed.

Hopefully, your blender has a tamper that allows you to keep the ingredients moving smoothly, so it doesn’t have to be stopped and started so much.

If the batter is too thick to blend, add a splash more of almond milk and blend a bit more.

My favorite blender is the Vitamix 5200 because it is so powerful, it can blend anything. I actually own two of them because I use them in the Food for Life classes I teach for the Physicians Committee for Responsible Medicine.

STEP #4: Spoon the batter into a mixing bowl and add the dairy-free chocolate chips and walnut pieces. Fold them together well with a sturdy spoon or spatula.

STEP #5: Evenly distribute the batter into an 8″x 8′ baking dish lined with parchment paper to prevent sticking to the sides. Use a spatula or spoon to smooth out the top.

I like to sprinkle the top with a few extra chocolate chips and walnuts but that is completely optional.

STEP #6: Bake at 350°F for approximately 20-25 minutes until you see the edges begin to get darker brown. Remove from the oven and allow to cool before serving.

Absolutely! This recipe calls for 1.5 cups of beans canned or fresh.

What can I use to substitute for brown sugar?

Date sugar, date syrup, and maple syrup are great options.

Notes

Tips & Suggestions:
I have included step-by-step photos and directions above to ensure your first attempt will be successful.
Oat flour- You can purchase oat flour online, but it is expensive. It’s so easy to make your own oat flour in a blender.
Sweetener- I use brown sugar, but the options could be date sugar, maple sugar, maple syrup, or others.
Black beans- This recipe calls for 1.5 cups of beans which is exactly the amount in a 15 oz can. You can always make your own fresh.
Storage- Store in an airtight container in the refrigerator for up to 7 days. They freeze well too.

  1. Do you think I could double this recipe and bake it in a 9×13 pan? If so, do you have a guess-timate on how long to bake?

  2. These are wonderfully delicious!! My family all loved them! I ended up using more plant-based milk (about 3/4 cup) but other than that, I followed the recipe to a T. So wonderful! Thanks for sharing!

  3. Hi! I live in Argentina and Iam so happy I found you! Cold you please recommend a susttitute for the apple sauce? We don’t hVe store bought here and making my own will delay the process… And I am excited to start asap

    1. Hi CT- I think date sugar would be a good substitute in equal measure. I haven’t tried syrup but think it could work in equal measure as well, but you may need to add another 1/4 cup oats because they are liquid.

  4. Mate, the recipe for the oil-free vegan and gluten free brownies was so easy to prepare. The brownies baked very nicely at 180’C’ for 25 minutes.Taste test to follow, however the sponginess of the baked brownies tells me they will be delicious.
    Thanks for sharing the recipe!!
    P.S. I didn’t add so much sugar, rather I addef two tbsp of applesauce plus a extra 1/4 cup blended rolled oats to soak up the extra moisture.
