Vegan black bean brownies with peanut butter frosting

Healthy and delicious dessert, both at the same time, is it possible? Yes, it is, and this recipe will prove it! These vegan black bean brownies are so tasty you won’t believe what’s hiding in there. Serve it to friends, but wait till the end before revealing the secret ingredient to see their expression totally in shock. It is so rewarding.

What are the key ingredients to make these vegan black bean brownies?

The base is made out of black beans! Nutrient dense and fiber packed canned black beans! You won’t taste them and it provides a perfect texture when making dense and chewy brownies.

Also part of the base, you will find lots of oats instead of flour. The oats are crushed in a food processor, so in this case too, you won’t realize they are there. They provide even more fiber and precious nutrients.

Now I hear you wondering where is the sweet taste coming from, its a dessert after all, right? Medjool dates to the rescue, once more. The sticky sweet, caramel-like and chewy dates also help hold everything together.

Cacao vs cocoa?

Both comes from the cacao bean (seed) and usually are used to prepare chocolate products.

But here is the main differences:

CACAO is the unprocessed option. This means that the bean is cracked out of its shell, ground and packaged. Its mostly used for vegan and unprocessed chocolate product. It contains a load of anti-oxidants and is therefore the healthiest version.

COCOA is the processed option. The beans are removed from their shells, but then brought to a factory where the beans are roasted in high heat and processed, then ground into cocoa powder. The manipulation of the beans makes cocoa a less healthy option since lots of its health benefit (anti-oxidants) have been eliminated in the process.

How to make these vegan black bean brownies?

You will have to first boil the dates in water for 5 minutes to soften them.

Then, add them and the other ingredients (except for the chocolate chips) to a food processor to prepare the dough. Super easy! Transfer to a bowl and fold in the chocolate chips.

The dough goes in a square oven safe container and pop in the oven.

Once the brownie is cooked, top it with an easy and delicious 5 minutes peanut butter frosting. You only need 4 ingredients, one bowl and a little whisk to make this healthy frosting!

This brownies is also delicious eating cold, so it makes for a perfect dessert to make ahead! Just prepare it when you have more free time, store it in the fridge and you will have a satisfying healthy dessert for your busy week to come.

Keyword: Vegan
Servings: 9 squares


  • Food processor


  • 15 large medjool dates (about 1 packed cup) pitted
  • 15 oz canned black beans rinsed and drained very well
  • 1 cup old fashioned oats
  • 1/4 cup raw cacao powder + 2 tbsp (not cocoa)
  • 3 tbsp coconut oil
  • 2 tbsp chia seeds
  • 1 pinch of salt
  • 1 tsp baking powder
  • 3/4 cup vegan chocolate chips


  • 1/2 cup smooth unsweetened peanut butter
  • 3-4 tbsp maple syrup
  • 1/2 tsp vanilla extract
  • 2 tbsp unsweetened almond milk


  • Pre heat the oven at 325°. Line a 8×8 baking dish with parchment paper.
  • In a small pot, combined the medjool dates with 1 cup of water and bring to boil. Once the boil has started, set the timer for 5 minutes and keep on boiling. Then, drain well in a colander and press gently on the dates with a spoon.
  • In a food processor, process the soften dates, drained black beans, oats, cacao powder, coconut oil, chia seeds and the salt for at least one minute taking a break or two to scrap the walls with a spatula. When the dough is well combined, add the baking powder and pulse few times to incorporate it. The dough should be thick and sticky.
  • Transfer the dough to a bowl and combine the chocolate chips with a spoon. Again, the dough is thick so you will have to work a little to mix them in.
  • Transfer the brownie batter to the prepared baking dish and even it by pressing gently on it using your hands.
  • Cook in the oven for 30 minutes.
  • Make the frosting by whisking all the frosting ingredients in a medium bowl.
  • Spread the frosting on the brownies while still keeping it in the baking dish (no need to let it cool down first).
  • This step is important: put the frosted brownies in the fridge for at least 3 hours before removing from the baking dish, cutting and eating.
  • Take the brownies out of the baking dish by pulling on the parchment paper and cut in squares. Enjoy!

    I made these for a small party with some friends and they were such a hit! I love that they are moist and chewy just the way a brownie should be – I couldn’t taste the black beans at all but knowing they were there made me feel so much better knowing I was enjoying a healthy treat. My friends loved these too and I directed them to your blog! The peanut butter frosting was so good. Thanks for another great recipe Jessica!
