Easy Black Bean Brownies

Easy Black Bean Brownies

This bizarre experiment stemmed from two emotions I experienced on a lazy Saturday afternoon.

One was the insane craving for chocolate. Sometimes I temporary silence this craving by eating a handful of chocolate chips usually reserved for baking, but this day was not the case. On my trip to the kitchen, to the baking cupboard, to the large bag of chocolate chips usually only reserved for baking, my Ghirardelli brownie box caught my eye. And I remembered that I still had one pack left of brownie mix.

Two was the sad and lazy realization that I had used up the last of the eggs the night prior, making muffins. I needed exactly one measly egg to make my beloved brownies and to cure my raging chocolate craving, otherwise the large bag of chocolate chips was going to get it! I didn’t want to go out and get eggs, see as how it was pouring rain outside. There had to be a better substitute! I turned to the internet for help.

I searched through a lot of helpful substitutions, such as mayo (we had none), eggs whites (if I had egg whites, I wouldn’t in this predicament, would I?) and canned pumpkin (must try later when canned pumpkin is on sale). I was almost about to use a convincing sounding baking soda and applesauce mixture when I clicked on a forum where someone raved about their black bean brownies. What got me more was that they even said they used the Ghirardelli brownie mixture I was about to use. I was sold.

So I found a can of black beans in the cupboard (I’m a big chili fan, so we always have beans in the cupboard, fresh or canned), rinsed them off and pureed them with a little bit of water in my undusted, unused and otherwise ignored food processor.

I started to get cold feet when I was spatula-ing out the pureed black beans onto my dry brownie mixture. There was no turning back now, I had black beans in the brownie mix. Then the paranoia set in: What if this turned out terrible? Was I insane for possibly wasting a precious batch of my favourite brownie mixture? I’m not a big fan of wasting food, so even if this tasted terrible, it would somehow have to be eaten. Unless it tasted really, really bad. Then I would feel major remorse throwing it in the trash.

Mixing the pureed black beans and dry brownie mix was a little odd at first, as it seemed that there was not enough wet mixture to go around and that I was just going to end up with very dry brownies. Eventually, the beans spread out and mixed with the dry ingredients and I had a very thick brownie mixture ready to go into a pan and into the oven.

I was also concerned 10 minutes after I put the pan in the oven because the smell of baked beans began wafting around the apartment. Did this mean that the brownies were going to have an obvious baked bean flavour? I didn’t want that at all! All I wanted was to tame my current chocolate craving. Was I being punished for my laziness?

The box says to cook the brownies for about 45-50 minutes, but my paranoia told me to check early and I’m glad I did. The brownies were ready at 35 minutes and because of the lack of eggs in the mixture, no real rising was involved. A quick toothpick in the middle told me that it was done and I set it to cool on an iron rack. I’m not going to lie, they look and smell delicious, even if they seem a little on the dense side.

(By now I had already caved in and had a handful of chocolate chips from the baking cupboard mostly out of nerves).

When I started the cut the brownies into squares, I noticed they seemed a little harder than usual. The tops were a little on the crisp side, as were the edges.

Finally, it was the ultimate test – I took a large piece and bit into it.

I can safely and honestly say that you cannot taste the black beans in the brownies. This was a huge relief, especially since my apartment still has a slight baked bean smell. The chocolate completely overshadows the beans in the mixture and the result is still a delicious, chocolaty brownie. However, these brownies aren’t as moist or spongy as the original mixture. I found the texture to be more like a chocolate cake than a brownie. Dare I say it, the brownies tasted healthier.

Now I’m secretly wondering if it made a difference that I rinsed the can of beans? I only did this out of habit due to the insane amounts of salt that are usually in canned beans. Maybe I should have just pureed it as is and then they would have resulted in moister, if not saltier brownies?

So by the looks of it, if you are looking for a healthier brownie substitute, this recipe does work. However, the results are a chewier and denser brownie. If you are looking for a traditional brownie texture (moist, spongy, etc), I suggest sticking with the normal combination of dry mixture, oil, egg and water.

Black Bean Brownies


  • 1 box dry brownie mix (I used Ghirardelli)
  • 1 can black beans (540mL)
  • 1/4 cup water (omit if you don’t want to rinse the beans)


  1. Rinse beans under water and puree until the beans resemble paste.
  2. Combine with dry brownie mixture and follow pan size and baking directions on the box.
  3. Check on your brownies after 30 minutes to see if they need to be in longer. Cool before cutting into squares.


PS: As a final note, I’ll admit that after eating two brownies, I was stuffed. Maybe that’s why dieters love this brownie recipe – the fiber in the beans fill you up and make you less likely to finish off the rest of the pan.

  1. Well, black bean is a weird ingredient (for me) for a brownie. But I think this would work. I hope the kids won’t notice the beans.

  2. In all the other versions I’ve found online, you’re supposed to rinse the beans, return them to the can, and fill it back in with water to where it was originally. THEN, proceed to run them through the blender or food processor. I’ve had no problem with them being too dry. They still don’t rise the way they do normally, but they’re great!

  3. I also add 1/2 cup of raw almonds or whatever nuts I have (ground into a flour texture) and a 1/2 teaspoon of almond extract as well.

  4. Another suggestion I found online…another cook was trying a new brownie recipe, and half-way through baking, she took them out to test for doneness. She was then distracted, and didn’t return the brownies to the oven to finish baking for 15 minutes. She decided to finish baking them, figuring that she couldn’t possibly ruin them any more than she already had. She baked them the total time as according to the baking time on the package. Her unintended error resulted in an incredibly chewy, moist, fudgy brownie, which is precisely how I prefer them! If you prefer a more cake-like brownie, then this brownie recipe isn’t for you, and they don’t really rise much at all. However, I made a batch using a can of low sodium black beans and a standard brownie mix, and they turned out wonderfully, in my opinion. I hadn’t read any of the suggestions to drain the beans and add water to remove more sodium, but I think I’ll try that this afternoon and see how that turns out. Nonetheless, if you love a chewy, fudge-like brownie, then this one will be right up your alley! Hope you enjoy as much as I have!
