Fudgy Black Bean Brownies Recipe with Easy Cacao Frosting (GF, Naturally Sweetened)

This black bean brownie recipe (with cacao frosting!) might just blow your mind. Imagine a rich, fudgy and supremely chocolatey brownie with a luscious texture that melts in your mouth. What if I told you that the brownie is made with black beans instead of flour, that it contains no refined sugar? Oh yes, my friends, these black bean brownies are going to astound you.

Black bean brownies with cacao frosting

I first saw black bean brownie recipes pop up on the web a few years ago, and I must admit, I was skeptical. Black beans? In brownies? But curiosity eventually got the best of me, and I was shocked at the outcome. The black beans give the brownies a luscious, almost fudge-like texture. The beans are completely undetectable (trust me, Ella can spot a bean anywhere, and she LOVES these!).

How to make black bean brownies

This easy batter is made right in a high-speed blender or food processor.

  1. In a high-speed blender or food processor, combine drained and rinsed black beans, maple syrup, eggs, coconut oil, cacao powder, vanilla, coffee liqueur and salt. Blend on high until completely smooth.
  2. Add the almond flour and baking powder. Blend on low just until incorporated.
  3. Add the chopped chocolate and pulse to combine.
  4. Spread the batter in a parchment-lined 8x8-inch square baking pan.

Making the cacao frosting

The frosting is made with just cacao powder, coconut oil, maple syrup and vanilla. The ingredients are stirred together until shiny and smooth. I love raw cacao powder for its rich chocolate flavor, but you could use a high-quality cocoa powder instead.

The cacao frosting is then slathered over the cooled brownies, taking them over the top.

Fudgy Black Bean Brownies with 2-Minute Cacao Frosting (Gluten-Free, Dairy Free, Naturally Sweetened)

These super fudgy black bean brownies are supremely rich and chocolaty with a melt-in-your-mouth texture. Best of all, they come together in minutes right in a high-speed blender or food processor! I prefer to use raw cacao powder in these brownies, as it has a deeper flavor than regular unsweetened cocoa powder (it also happens to be higher in antioxidants). If you go for cocoa powder, just choose a high quality brand.
Servings: 16 brownies
Prep Time: 20 minutes
Cook Time: 25 minutes
Total Time: 45 minutes

Ingredients

For the brownies:

  • Cooking spray or oil, for pan
  • 1 cup drained and rinsed unsalted black beans
  • ½ cup maple syrup
  • 2 large eggs
  • ¼ cup virgin coconut oil, melted and cooled slightly
  • ¼ cup raw cacao powder or unsweetened cocoa powder
  • 2 teaspoons vanilla extract
  • 2 teaspoons coffee liqueur or strong brewed coffee
  • ½ teaspoon fine sea salt
  • 2 tablespoons almond flour
  • ½ teaspoon baking powder
  • cup finely chopped bittersweet chocolate or mini chocolate chips

For the frosting:

  • ¾ cup raw cacao powder or unsweetened cocoa powder, sifted to remove any lumps
  • cup virgin coconut oil, melted and cooled slightly
  • cup maple syrup
  • 1 teaspoon vanilla extract
  • Pinch salt

Instructions

Make the brownies

  • Preheat the oven to 350˚F. Grease an 8-inch baking pan with coconut oil or cooking spray. If you'd like, line the pan crosswise with parchment paper, leaving an overhang (this will make it easy to pull the brownies out later).
  • In a high-speed blender or food processor, add the black beans, maple syrup, eggs, coconut oil, cacao powder, vanilla, coffee liqueur and salt. Blend on high until completely smooth (stop and scrape the sides as needed). Add the almond flour and baking powder. Blend on low just until incorporated. Add the chopped chocolate and pulse to combine.
  • Scrape the batter into the prepared baking dish, and spread it in an even layer. Bake until the brownies look matte on top with a few small cracks, and a toothpick inserted in the center comes out mostly clean with a few sticky crumbs, 25-30 minutes. Set the pan on a wire rack, and let cool completely. Using the parchment paper as handles, transfer the brownies to a cutting board or platter.

Make the frosting

  • For the frosting, sift the cacao powder into a bowl and add the maple syrup, coconut oil, vanilla and salt. Using a rubber spatula (and working quickly so that the coconut oil doesn't harden), gradually stir everything together until smooth and thick. Immediately spread the frosting over the brownies (don't dally, as if the coconut oil starts to harden the frosting could turn grainy). Let the brownies sit at room temperature or refrigerate them to allow the frosting to firm up (or just dive on in; I’m not judging!).
  • Cut the brownies into 16 squares, and enjoy!

Notes

Do Ahead: The brownies can be covered and stored at room temperature for up to 3 days.

  1. Hi Nicky, I do wish you would also provide weight measurements (preferably metric but my scale can also handle imperial units). Weighing ingredients is much more accurate as well as convenient.
    These brownies look delicious but the cup measurements are putting me off.

    1. Hi Lyn, I haven't tested these brownies with cassava flour so can't guarantee the results. Yes, you can skip the coffee!

  2. Hello. Can I use pinto beans? The problem is we are on quarantine and we have no almond flour available. What is the best sub for it?

    1. Hi there! I haven't tested these brownies with pinto beans, but I do think they should work. As far as the almond flour goes, you can use regular all-purpose or gluten free flour instead, although the brownies won't be quite as tender. Happy baking, and keep me posted!

    Hey Nicki! This is Raine! I made these a few weeks ago and they were so good!!!!!! They were even better the next day because they had hardened in the refrigerator and they were so fudge like and DELICIOUS! Thank you for this recipe. So easy, so yummy and so healthy!

    🙂

    These are absolutely delicious, incredibly easy, guilt-free and a total crowd pleaser at my house (and we like flour and sugar and butter!).

  5. These were soooo yummy and decadent! Today’s snow day a perfect excuse to make them again!

  6. Hi-Can you suggest a non-alcoholic substitute for the coffee liqueur? I would love to make the brownies but I can't have the liqueur.
    Thanks!
