Black Bean Brownies are a great example of how a single technique can transform a recipe from “interesting experiment” to “go-to favorite.” If you’ve ever worried about baking with beans, you’re not alone. The key here is getting the batter completely smooth before baking. This isn’t just about hiding the beans—it’s about achieving that classic brownie texture: dense, fudgy, and cohesive, without any hint of grittiness. I’ve found that using a food processor and blending until the mixture is absolutely creamy makes all the difference. If you stop too soon, you’ll end up with a slightly chunky batter, and the brownies won’t have the right mouthfeel.
Another detail to pay attention to is how you incorporate the chocolate chips. Stir them in by hand after blending, so they stay whole and give you those little pockets of melted chocolate in every bite. This small step is what takes these brownies from “healthy alternative” to “legitimately crave-worthy.”
Black Bean Brownies are useful when you want a treat that’s a bit more nourishing but still feels indulgent. They’re gluten-free by default, and you can easily adjust the sweetness or swap in different oils depending on what you have. I like making these when I want dessert to double as a snack—something you can pack for work or share with friends who might be skeptical about beans in brownies. Once you master the blending and folding techniques, you’ll see how easy it is to get consistent, delicious results every time.

What Goes In
- 1 1/2 cups cooked black beans (about one 15-oz can, rinsed and drained well)
- 2 teaspoons pure vanilla extract
- 1/2 teaspoon baking powder
- 1/3 cup pure maple syrup (or honey/agave, about 75g)
- 1/4 teaspoon salt
- 1/2 cup quick oats (40g)
- 2 tablespoons unsweetened cocoa powder (10g)
- Pinch of uncut stevia or 2 tablespoons sugar (optional; leave out if you increase maple syrup to 1/2 cup)
- 1/4 cup coconut oil or vegetable oil (40g)
- 1/2 to 2/3 cup chocolate chips
- Extra chocolate chips for sprinkling on top (optional)
Let’s Begin
- Preheat your oven to 350°F (175°C). Lightly grease an 8×8 inch baking pan so the brownies release easily after baking.
- Add the black beans, vanilla extract, baking powder, maple syrup, salt, oats, cocoa powder, stevia or sugar (if using), and oil to a food processor. Blend until the mixture is completely smooth and creamy. Take your time here—stop and scrape down the sides as needed. The batter should have no visible bean pieces or oat flakes.
- Remove the blade from the processor. Gently fold in the chocolate chips with a spoon or spatula. This keeps the chips whole and evenly distributed.
- Pour the batter into your prepared pan. Spread it into an even layer. If you like, sprinkle extra chocolate chips on top for a more chocolatey finish.
- Bake for 15 to 18 minutes. The brownies will look set at the edges but still soft in the center. Don’t overbake—they’ll firm up as they cool.
- Let the brownies cool in the pan for at least 10 minutes before slicing. If they seem too soft, refrigerate them overnight to help them set perfectly.
Ingredient Swaps for Maximum Flexibility
If you’re missing an ingredient, there are plenty of ways to adapt this recipe. You can use honey or agave in place of maple syrup—just keep the total liquid sweetener amount the same. For the oil, both coconut and vegetable oil work, but you can also use melted butter or a neutral-tasting olive oil if that’s what you have. Quick oats can be swapped for rolled oats, though you may want to pulse them in the processor first for a finer texture. If you’re out of chocolate chips, try chopped dark chocolate or even a swirl of nut butter for a different twist. For a nut-free version, double-check your chocolate chips and use a neutral oil.
How to Serve It for Any Occasion
These brownies are versatile enough for any setting. For a casual snack, just slice and serve straight from the pan. If you’re bringing them to a gathering, cut them into small squares and dust with a little cocoa powder or powdered sugar for a polished look. For dessert, serve warm with a scoop of vanilla ice cream or a dollop of whipped cream. They also work well as a lunchbox treat since they hold together nicely once cooled. If you want to make them extra special, drizzle with melted chocolate or top with fresh berries.
Make-Ahead and Storage Hacks
Black Bean Brownies are perfect for making ahead. Once baked and cooled, store them in an airtight container at room temperature for up to two days, or in the fridge for up to a week. For longer storage, wrap individual squares tightly and freeze for up to three months. To serve from frozen, let them thaw at room temperature or warm briefly in the microwave. If you want to prep in advance, you can blend the batter and refrigerate it (covered) for up to 24 hours before baking. Just give it a quick stir and proceed as usual.
Timesaving Tips and Tricks
Using canned black beans saves a lot of time—just be sure to rinse and drain them well to avoid any extra salt or bean flavor. A food processor is the fastest way to get a smooth batter, but a high-powered blender works too. If you want to cut down on cleanup, measure your wet ingredients first, then reuse the same measuring cups for the dry ones. Line your baking pan with parchment paper for easy removal and less scrubbing. If you’re in a rush, skip the extra chocolate chips on top—they’re optional.
How to Adapt This Solution for Different Seasons
In winter, serve these brownies warm with a mug of hot cocoa or coffee. For spring, add a handful of fresh raspberries or strawberries on top before baking. In summer, pair with a scoop of ice cream and fresh fruit for a lighter dessert. During fall, try adding a pinch of cinnamon or a swirl of pumpkin puree to the batter for a seasonal twist. These brownies are easy to customize with spices, extracts, or toppings to match any time of year.
Your Questions Answered
Can I make these brownies without a food processor?
Yes, you can use a high-powered blender instead. If you only have a regular blender, work in batches and scrape down the sides often. The goal is to get the batter as smooth as possible. If you mash by hand, the texture will be more rustic and the brownies may not hold together as well, but they’ll still taste good.
Why do my brownies taste “beany”?
If you notice a bean flavor, it’s usually because the beans weren’t blended thoroughly or weren’t rinsed well enough. Rinse the beans until the water runs clear and blend the batter until completely smooth. Adding a bit more cocoa powder or vanilla can also help mask any lingering flavor.
Can I double the recipe for a larger crowd?
Absolutely. Double all the ingredients and bake in a 9×13 inch pan. The baking time may increase by a few minutes, so start checking at 18 minutes and continue until the edges are set and the center is just slightly soft. Let cool before slicing for the best texture.
What if I don’t have quick oats?
You can use rolled oats instead. If you want a finer texture, pulse the rolled oats in your food processor or blender before adding the other ingredients. This helps the brownies hold together better and gives a smoother crumb.
How do I know when the brownies are done?
The edges should look set and slightly pull away from the pan, while the center will still be soft. Don’t wait for a dry toothpick—these brownies are meant to be fudgy. They’ll firm up as they cool, so avoid overbaking for the best result.
Is it possible to make these brownies vegan?
Yes, as long as you use dairy-free chocolate chips and stick with maple syrup or agave as your sweetener, these brownies are completely vegan. Double-check your chocolate chips to ensure they’re vegan-friendly, and you’re all set.
