These black bean brownies are rich, deeply chocolatey, and incredibly fudgy, all without any flour. The texture is smooth and dense, and the flavor is pure brownie, with zero aftertaste.
“Yummy! These came out really nice! … Very glossy, dark chocolatey but also not too sweet, and felt wholesome to eat! Thank you Nicole! I’ve always wanted to try bbbs and this was the perfect recipe!”
Why this recipe works
Most black bean brownie desserts still taste at least a little like beans. Here, the cocoa powder, brown sugar, brewed coffee, and melted chocolate work together to create nothing but deep chocolate flavor.
The texture is what surprises most people. The top may look cake-like, but the center stays dense, smooth, and fudgy all the way through.
Just blend together the black beans with eggs and oil, mix or blend in cocoa powder and sugar, stir in the chocolate chips, and bake for the rich texture of a classic brownie without any flour at all.
Recipe ingredients
The ingredient amounts are in the full recipe card below. Here’s a closer look at the key ingredients for my black bean brownie recipe and what role each one plays in the end result:
- Black beans: The base of the recipe that provides most of the structure Use a good-quality canned variety. Rinse and drain thoroughly until the water runs clear to avoid any beany flavor.
- Eggs: Help bind the batter together, since there’s no flour to provide structure.
- Cocoa powder: Use Dutch-processed for a deeper chocolate flavor, or natural if that’s what you have.
- Oil: Combines with cocoa powder to create a rich, smooth chocolate texture.
- Brown sugar: Adds sweetness, moisture, and depth of flavor from the molasses.
- Pure vanilla extract: Enhances the chocolate flavor.
- Brewed coffee: Deepens the chocolate flavor without making the brownies taste like coffee. Decaf is fine, or you can replace it just some lukewarm water.
- Baking soda: Reacts with the brown sugar and cocoa to help the brownies rise, and neutralizes any acid in natural cocoa powder if you use it.
- Salt: Balances the sweetness and brightens the chocolate taste.
- Chocolate chips (optional): Add pockets of melty chocolate and texture contrast.
How to make black bean brownies
Follow along with my directions below to see how to make black bean brownies in your own kitchen, plus an explanation for the reason behind each step:
1. Blend the wet ingredients
In a basic blender or food processor, combine the drained and rinsed black beans, eggs, oil, vanilla, and coffee. Blend until completely smooth to emulsify the eggs, oil and coffee to create a dense, fudgy and very moist crumb.
2. Mix the dry ingredients
In a large bowl, whisk together the cocoa powder, baking soda, salt, and brown sugar. Use a fork or the back of a spoon to break up any lumps in the sugar to avoid any unpleasant hard pockets in the brownies.
3. Combine
My blender wasn't big enough to hold all of the batter, so I usually pour the blended bean mixture into the dry ingredients and stir until smooth. If you're using a large enough blender, add the cocoa powder, baking soda, salt and sugar to the blender and pulse to combine. Either way, the batter will be very soft.
4. Add chocolate chips (optional)
Stir in about half the chocolate chips, if using. We don't use too many chips because the batter doesn't have enough structure to keep them all suspended during baking, so they'd sink to the bottom.
5. Transfer and top
Spread the batter evenly in a greased and lined 8-inch square baking pan. Sprinkle the rest of the chocolate chips on top and press them in lightly so they stick rather than lifting off the batter as it rises in the oven.
6. Bake at 325°F
The brownies are done baking when the top is set, springs back gently in the center, and the pan doesn’t jiggle when shaken. A toothpick or cake tester may still come out a bit too moist even when the brownies are done baking, so other doneness tests are more accurate here. Baking time is usually about 25 minutes.
7. Optional for cakier brownies
Lower the oven to 300°F and bake for 3 to 5 more minutes for a firmer center. It can be difficult to tell when dark brownies are done baking, so be careful not to overbake.
8. Cool, chill & slice
Let the brownies cool in the pan on a wire rack since they're very fragile when still warm. For clean slices, chill the pan in the refrigerator for 30 minutes or freezer for 10, then lift out and slice into 9 squares with a sharp knife, wiping between cuts.
Expert tips
Use a blender for a smooth texture
A blender makes the black bean mixture as smooth as possible, which gives you the creamiest brownies. A food processor works too, but may leave some unwanted texture, but either method should properly combine the eggs and oil for fudgy brownies.
Choose a light-colored 8-inch pan
A dark or oversized pan can cause the edges to overbake before the center sets fully. Stick with a light-colored metal pan for the best results.
Be careful with baking times
Bake at 325°F until the center is just set and no longer jiggles when the pan is shaken. If you prefer a cakier brownie, lower the oven to 300°F and bake for 3 to 5 more minutes.
Chill before slicing
Cool the brownies completely, then chill the pan before cutting. A cold brownie and a clean knife means tidy squares.
Ingredient substitutions
This recipe is pretty flexible. Here's how to adapt it for different dietary needs:
Dairy free
They're already dairy-free, just use dairy-free chocolate chips.
Egg free
Try boiled flax eggs in place of the two eggs. “Chia eggs” wouldn’t provide enough structure here.
Sugar free
Coconut palm sugar should work in place of brown sugar (though untested). For sugar-free options, try Swerve or Lakanto brown sugar replacements.
Tip: These tend to dry out baked goods, so add 1–2 extra tablespoons of brewed coffee to balance the moisture.
No coffee
You won’t taste it and it’s there to boost the chocolate. You can replace it with an equal amount of milk or water. For added flavor, try 1½ tablespoons (32 g) pure maple syrup instead.
Choosing an oil
Stick with neutral oils like grapeseed, canola, vegetable, avocado or peanut oil. Avoid olive oil, which has too strong a competing flavor.
Storage instructions
Store leftover brownies in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week.
For longer storage, freeze in a single layer on a lined baking sheet until firm, then transfer to a sealed container. They won’t freeze solid, so you can enjoy them straight from the freezer or let them come to room temperature if you prefer.
Black Bean Brownies Recipe
Equipment

- ½ teaspoon baking soda
- ¼ teaspoon kosher salt
- ¾ cup (164 g) packed light brown sugar
- 3 ounces semi-sweet or dark chocolate chips, optional
Instructions
- Preheat your oven to 325°F. Line an 8-inch square light metal baking pan with nonstick foil, greased regular foil, or parchment. Set aside.

These brownies are rich and fudgy, but not chewy. For a chewy texture, try my classic gluten free brownies recipe.
Yes, if you cooked them in plain water alone. If they're made with stock, they'll have a distracting savory flavor that doesn't mix well here.
Yes! Line a standard 12-cup muffin tin, fill each well about 2/3 full, and bake for about 18 minutes, or until the tops spring back when gently pressed. Cool completely before removing.
Not at all. As long as you rinse the canned beans well, these brownies just taste like rich, chocolatey brownies, no bean flavor.
Yes! You can make them a day or two ahead and store them in the fridge. For longer storage, freeze them and enjoy straight from the freezer or defrost as needed.
I made these today. And I’m not sure what I did wrong they are crumbly. The top lifts off and everything else is crumbs. They taste great. Any suggestions??
That’s usually due to overbaking, Allison, usually in a too-hot oven. I’d take a look at whether you measured your ingredients by weight, not volume, and especially if you made any ingredient substitutions, like trying to avoid eggs. The main binder in this recipe, and also what provides structure as the brownies cool, is eggs in the absence of any flour. The simplest recipes are the ones that typically require the strictest adherence to the recipe.
So good. I used 1/2 cup of coconut sugar in place of the brown sugar & walnuts in place of the chocolate chips. I had so many compliments on these. Perfect for gluten free & anti inflammatory diets.
So glad to know that coconut sugar worked in place of brown sugar, Truly. Thank you so much for sharing your experience!
I have made these about 50 times, fierce handy for a shared lunch as it’s gluten free. Whip it up in the nutribullet and into the oven. I leave it in for 35 in a good oven and about 40 otherwise
Wow, Alanna, so glad you commented about that. That’s a tried and true recipe. Thanks for sharing your love of it!
