Vegan Flourless Black Bean Brownies

Ever since I posted my White Bean Blondie recipe last year, I’ve had several people ask me if I had tried working on a black bean brownie. Because there are already quite a few black bean brownie recipes to be found online, I wasn’t sure if I could contribute anything new and exciting to the world, but I’m glad I tried because I think these are one of the BEST brownies I’ve ever tasted– healthy or otherwise.

Whenever I decide to try to develop a new recipe, one of the first things I do is a quick Google search to see what has already been done. I usually try to make the first few results that come up in my search, just to see if there is already a “perfect’ recipe out there, but in the case of black bean brownies I was pretty disappointed in the results. None of them were truly “brownie-like” enough for me.

Perhaps that’s because I’m pretty picky about my brownies. To me, a good brownie needs to be rich and moist, with a fudge-y texture. I mean, if I wanted a cake-like texture, I’d reach for a piece of cake. Brownies need to feel more moist and decadent.

What I love about these Black Bean Brownies is that they are:

  • Flourless! (which also keeps them gluten-free)
  • Naturally sweetened with coconut sugar
  • Oil-Free
  • Loaded with fiber and protein from black beans
  • Sneaky– you can’t detect the black bean flavor AT ALL.
  • Rich and fudge-like

Trust me when I say that these brownies taste totally decadent.

This is the BEST black bean brownie recipe I've ever tasted. No eggs, flour, or dairy, so they are vegan and naturally gluten-free. So rich and fudgy!

  1. Preheat the oven to 350ºF and line a 9-inch square baking dish with parchment paper. In a large food processor fitted with an S-blade, process the black beans until smooth.
  2. To the pureed black beans, add in the almond butter, cacao powder, ground flax, vanilla, sugar, vinegar, salt, and baking soda. Process until a very smooth and thick batter is formed, stopping to scrape down the sides at least once to make sure everything is mixed evenly.
  3. Add the chocolate chips to the batter and pulse a few times to mix them in. Use a spatula to scoop the batter into the lined 9-inch baking dish. The batter will be rather thick, so you'll need to use the spatula to spread it evenly into the pan.
  4. Bake until the top begins to crack and the center feels relatively firm to a light touch, about 30 minutes. Allow the brownies to cool completely before attempting to cut them into squares, as they are very fragile when warm.
  5. Serve at room temperature, and store any leftovers in an airtight container in the fridge for up to a week. (I imagine these would freeze well, too!)

Substitutions & Notes:

  • If you prefer a darker chocolate brownie, go ahead and use 1/2 cup of raw cacao powder in this recipe. I’ve tested it that way, and I thought they were delicious, but they were a little “too dark” for some of my taste testers.
  • I imagine that any other nut or seed butter, such as peanut butter or sunflower seed butter, would work well in this recipe if you’d prefer to replace the almond butter.
  • If you don’t have balsamic vinegar on hand, I think another vinegar would probably work well, too. You just need some sort of acid to react with the baking soda. (And I think balsamic pairs really nicely with chocolate recipes.)
  • Coconut sugar gives these brownies much of their substance and texture, so don’t be tempted to use a liquid sweetener or sugar substitute without expecting significantly different results. Granulated sugar = chewy, fudgy brownies, so keep that in mind.
  • As always, if you try something different please leave a comment below so we can all benefit from your experience.

Hope you enjoy these rich and fudgy brownies!

This recipe posted the week that I found out that I was allergic to chocolate, and I was super bummed that I wouldn’t be able to try it. Last week, however, I decided that I would give carob a shot. I first tried it in avocado pudding — which I used to eat pretty much every day — and it really didn’t work flavor-wise. I am not sure who these people are that claim that carob is just as good as chocolate, but I will definitely not be joining their club. Having accidentally ordered 4 pounds of carob powder from Amazon, however, I decided that I needed to keep trying. So, I decided to give this brownie recipe a try. Keep in mind that I am also off of nuts for the foreseeable future, so I needed to substitute the almond butter for sun butter — so I was more than a little surprised that they were kind of delicious. I added several drops of peppermint oil to help mask the carob, and that worked really well. And I also needed to sub the delicious dark chocolate chips for white chocolate. All in all, they turned out great, and I will definitely be making them again.


Have you ever baked with date sugar? Could date sugar be substituted in this recipe?


Just made these yesterday for some friends (one who is vegan and two who are gluten free and only eat natural sugars). They absolutely loved them, as did i!

I do not have a food processor, so I tries the mashing by hand method someone suggested in the comments. It worked for the most part, but I had to go back and mix the beans up with a fork. I but them in a medium-ish plastic measuring cup for smashing and then used a fork to do the rest. A bit time consuming, but totally worth it.

I also skipped out on the balsamic vinegar (because I don’t really like it) and they still tasted amazing.


    Sorry for all the typos! Using my phone to write this. Hopefully you understood the basis of what I was saying.


I just made these brownies and they are very good. I can’t wait to have another one tomorrow morning. I like that I was able to throw everything in the food processor and mix away.


My favourite brownie recipe! I use an egg instead of the flax and they turn out great 🙂 thanks for the awesome recipe!


Cooked for slightly less time for them to be a little gooey. Used almond flour instead of flax (i didn’t have any flax on hand) and they turned out fabulously! Everyone LOVED them. Now, i have to make a double batch or they don’t last more that 24 hours.


Just made these tonight! These are really fudgy, thick brownies! I couldn’t resist and ate these as soon as they came out of the oven. They are much better texture-wise as they sit like you said! 🙂 I’m going to chill these overnight to thicken the texture.

I used ingredients I had on hand: smooth almond butter, non-alkalized cocoa powder, granulated sugar and golden flaxmeal.

The flavor is incredible and I’m considering adding another tablespoon of ground flax to thicken the batter and give the brownies a little more structure. Overall a fantastic recipe and a great way to use black beans, thank you for sharing!


A success! If you do not say anything, your guests cannot guess it is a vegan and healthy cake.
The perfect indulgent treat!


These are absolutely delicious. I reduced the sugar to 2/3 cup and still really good.

Do you have a recipe for chick pea bolindies?

Thanks for this great recipe and all the work you do. I am a faithful follower!


Just made these. They’re so so good!! Thank you Megan!

Yum. Made these with peanut butter instead of almond and used ground oats and agave instead of coconut sugar. Also yum.

Made these brownies today and they’re delicious. Better than my other BB Brownie recipe (using oats). One thing I noticed…a can of black beans is 2 cups. The recipe states 1-1/2 cups. I was worried about them being too dry so went with 1-1/2 cups. Glad I did…I think the full can would have been too much.


These are fantastic!! I had to make some last-minute substitutions because I ran out of a few things, but they STILL turned out 100% better than any other attempt at black bean brownies I’ve ever made. And I’ve recently discovered that gluten gives me lung inflammation, so I’m loving these more than ever. And my meat-eating friends just polished off two each without knowing they were mine!


I know you posted these awhile ago but I finally had an opportunity to make it….& wow, are they fantastic!!! Both my kids loved them (without knowing the sneaky ingredients 😉)
They were easy to make and not overly sweet! Thank you for always coming up with healthier options for sweet treats! It’s a game changer when you have Little’s with GF/DF allergies.


perfect! loved! so tasty you can lick the bowl or better yet roll balls of brownie mix in GF rolled oats and freeze for a yummy breakfast on the go that tastes naughty but mmmm is so nice!

My husband was horrified that I was going to make brownies with black beans. However, he was soon eating his words and then eating 3 of the brownie squares! These brownies are amazing! Absolutely loved them and so easy to make. We also love your date-sweetened chocolate brownies and I am wondering if the coconut sugar in this recipe couldn’t be successfully swapped out for dates as both recipes have a fudgy texture. Just a thought. A huge hit in the house yesterday and I have a feeling I won’t have to worry about freezing them as they aren’t going to last long.

Just made these brownies for the second time with the date paste substitute and they turned out fabulously! Smoother consistency than when using coconut sugar. I preferred the sweetness level of these with the date paste more than with the coconut sugar which we both found a tad sweet. These were perfect. I swapped out 1:1 ratio and loved it. Will be making them again and again with the date paste. Thank you!


How about using dates instead of the coconut sugar? I have a recipe for black bean brownies that uses dates.


Since I’m not usually a fan of beans, I’ve always been so hesitate to try a bean brownie recipe. But because all your other recipes are always so good, I wanted to give it a try. Completely BLOWN AWAY! These brownies are rich and ADDICTING. Loaded with fiber and nutrients. Can’t taste any bean flavor at all!


Great recipe! The flavor was delicious and I don’t think my husband would have even known if I hadn’t told him it was made out of black beans.

The only thing is that mine were also pretty dry and very thick and did not rise as high as the ones in the photo. I added a little bit of water to help it blend in the food processor. Still tasted great though!


    I made these again and I think I used too much cacao powder the first time. I also kept the black beans a little wet after straining baked 20 min and they came out great!


Someone made these for me and I am in love. I want to make them as well, but I was wondering if I could add a scope of chocolate protein powder and if so would I need to alter the recipe for the extra dry ingredient?


Just made these !!! So delicious I’m impressed.


Decadent and delicious

Let me first start by saying – I am the queen of substitutions! I almost never have all of the ingredients for any recipe, and this recipe was no different. In this case, I substituted the coconut sugar for granulated sugar and the cacao for cocoa powder. I also misread the recipe a couple of times as well – 1 tsp of baking soda [instead of 1/2tsp – which is tried to rectify by scoping out some before mixing] and 6 tbsp of almond butter [instead of ¼ cup – which I only realised as the food processor was buzzing away].

Regardless, this was a fairly easy recipe to follow. I have a regular Cuisinart food processor and it was a little taxed when trying to blend the beans. Luckily I didn’t succumb to my urge to add any liquid! Once everything was added it blended to a lovely consistency.

After baking for the recommended time, the top of my brownies hadn’t cracked and it was fairly soft to the touch. I ended up baking them for another 20 minutes and left them cool overnight.

When I cut the brownies this morning, there were super moist and fairly delicate. They seemed to have a slightly bitter taste [I wonder if this was due to the extra baking time or the use of the cocoa powder]. They also have a slight grittiness to them [maybe the ground flaxseed?]. Other than those two issues, the brownies are quite nice – I doubt they will last the day. I think I will try them again, with the correct proportions and the recommended time, and maybe a little more time in the food processor.


I used eggs instead of flax seeds and they turned out great. If you aren’t going for a vegan brownie just use eggs in place of flax seeds. They are still gluten free and yummy!


I was wondering if I could double up the ingredients and bake thr


I don’t know what happened but my batter was just pure gritty powder … no moisture at all. I ended up adding two eggs, 1/4 cup coconut oil and about 1/2 cup almond milk. Still dry. I double checked my measurements and all were accurate. Maybe my almond butter wasn’t creamy enough or my food processor too small. We shall see how they turn out.


Delicious but feeling guilty about the sugar. Have you made these with date paste? I see you have another recipe for making date paste.


These are so fun (I mean black beans in a brownie?) and delicious. I have already made them twice and will make them many times in the future. Would love to discover an equally delicious way to make these without the coconut sugar, might have to play around a bit. Totally recommend – Thank you! Love your recipes.


Wow, these are amazing. I’ve never found a good black bean brownie recipe (they always have a weird texture and somehow taste “empty”), nor even a really good regular brownie recipe, but this recipe has changed things! They taste like brownies you’d buy at a fancy bakery. I wonder if the secret ingredient is the balsamic vinegar.

Monica Perez-Brandes

This was so good!!! My coworkers couldn’t believe it had no eggs, flour or dairy.


I’ve made these so many times and told everyone about them.. LOVE this recipe! What I don’t get is the high variability.. usually they’re the best brownies I’ve ever had; other times, they’re overly dense, undercooked on the inside, and almost scorched on the outside. I feel like it has to do with the baking soda/vinegar reaction. My mom has made two batches – one I remade immediately afterwards from the same ingredients, and it turned out perfectly. But recently I made a bad batch too, and this leaves me confused. I tested my baking soda and vinegar, and they are still good.

I’m not 100% conscious of the order I’m adding the ingredients, but I believe in this recent bad batch, I added the vinegar to the beans initially to help with blending. I think I did this the other times I’ve made good batches, too, but I’m not sure. If anyone has any suggestions, feel free to let me know 🙂 otherwise I’ll keep experimenting and let you know.
Thank you for the recipe!


These were absolutely DELICIOUS!!! I was always a skeptic about the idea of black bean brownies. I always thought there was no way to make something like that taste good, but WOW! These were fudgey, decadent and yummy, to say the least! Thank you for such a great recipe!!


I’ve tried other black bean brownie recipes, I’m going to try yours. I may use raw sugar in the recipe, halfway between processed white sugar and coconut sugar. I would want them sweet after all, they are brownies! (Maybe use Mexican sugar, which is less processed than American white sugar. It has a slight brown shade to it, as it still has some of the molassas, being less processed.


My daughter didn’t believe there were beans in her brownie. I had to show her your video! Then she ran to tell her sisters they had to try them. Another winner Megan! These are awesome!


I just baked this brownies but I’m substitute coconut sugar with dates.
