Ingredients for black bean peanut butter brownie
Twelve ingredients transform into decadent, protein-rich brownies with fudgy texture and nutty depth.
| Ingredient | Amount | Notes |
|---|---|---|
| Black Beans 🌱 | 1 can | Drained, rinsed, high protein |
| Creamy Peanut Butter 🥜 | ½ cup | Natural, unsweetened preferred |
| Unsweetened Applesauce 🍎 | ½ cup | Substitutes for eggs |
| Dark Chocolate Chips 🍫 | 1 ½ cups | 70% cacao minimum |
| All-Purpose Flour 🌾 | 1 cup | Gluten-free blend optional |
| Granulated Sugar 🍚 | ¾ cup | Coconut sugar works too |
| Cocoa Powder 🍫 | ½ cup | Natural, unsweetened |
| Vanilla Extract 🌸 | 1 tbsp | Pure, high-quality |
| Baking Powder 🍞 | ½ tsp | Aluminum-free preferred |
| Sea Salt 🧂 | ½ tsp | Fine grain, kosher |
| Melted Coconut Oil 🥥 | ½ cup | Substitute for butter |
| Crushed Peanuts 🥜 | ¼ cup | For garnish, optional |
| Powdered Sugar 🍚 | ¼ cup | For dusting, optional |
The black beans are the secret to moisture and protein without altering the classic brownie experience. Opt for canned beans with no added salt, and drain them thoroughly to avoid excess liquid in the batter. Trader Joe's and Whole Foods carry high-quality, organic options that enhance flavor. For the peanut butter, choose natural, unsweetened varieties—brands like Smucker's Natural or Jif Natural provide the right consistency without added sugars. The cocoa powder should be natural, not Dutch-processed, to maintain proper brownie texture and depth of flavor. Valrhona or Hershey's Special Dark are excellent choices for professional results.
No applesauce? Mashed banana or pumpkin puree work equally well as egg substitutes, though they may slightly alter moisture levels. Substituting tahini for peanut butter creates a Middle Eastern-inspired twist while maintaining protein content. For a gluten-free version, replace all-purpose flour with a 1:1 gluten-free blend like Bob's Red Mill. The chocolate chips can be swapped for chopped dark chocolate bars for a more luxurious texture. When measuring, pack the flour and cocoa powder firmly into the measuring cups for accurate volume. The vanilla extract should be pure—Nielsen-Massey or McCormick Pure extracts provide the best flavor without artificial additives.
Store these brownies in an airtight container at room temperature for up to five days, though they're best enjoyed fresh. For longer storage, wrap individually in parchment paper and freeze for up to three months. The peanut butter swirls solidify slightly when chilled, creating a delightful contrast to the fudgy base. Garnish with powdered sugar or crushed peanuts just before serving to maintain crispness. These brownies reheat beautifully—wrap in foil and warm in a 350°F oven for 10-15 minutes to restore their rich texture.

Step-by-step instructions for black bean peanut butter brownies
This method delivers rich, fudgy brownies with nutty depth and perfect texture every time.
Prepare the Black Bean Base
Drain and rinse the 1 can black beans thoroughly under cold water, then transfer them to a food processor. Pulse until completely smooth, scraping down the sides as needed. This step creates the moisture and binding that replaces eggs while keeping the brownies dense. The texture should resemble thick hummus with no visible chunks.
In a separate bowl, whisk together the 0.5 cup creamy peanut butter and 0.5 cup unsweetened applesauce until fully combined. This mixture will add the signature peanut flavor and moisture balance to the batter. I like to warm the peanut butter slightly (30 seconds in the microwave) first—this makes it easier to blend smoothly without graininess.
Combine Wet Ingredients
In a large mixing bowl, add the processed black beans, peanut butter-applesauce mixture, 0.5 cup melted coconut oil, 0.75 cup granulated sugar, 0.5 cup cocoa powder, 1 tablespoon vanilla extract, 0.5 teaspoon baking powder, and 0.5 teaspoon sea salt. Mix using a hand mixer on medium speed for 2-3 minutes until completely smooth and well incorporated.
The batter should be thick but pourable—similar to traditional brownie batter. If it looks too thick, add 1 tablespoon of water at a time until it reaches the right consistency. This is where the black beans' moisture content becomes crucial; don't worry if it seems different from traditional brownie batter.
Fold in Chocolate and Peanuts
Gently fold in the 1.5 cups dark chocolate chips and 0.25 cup crushed peanuts using a spatula. Be careful not to overmix—just combine until evenly distributed. The chocolate should be melted slightly by the warm batter, creating pockets of gooey goodness throughout each brownie. If you prefer extra peanut flavor, you can add an additional 2 tablespoons of peanut butter at this stage.
Here's the thing about these brownies—they rely on the black beans for moisture and structure, so don't be tempted to add extra flour. The batter should be thick but workable. If you're concerned about the texture, remember that these brownies will be denser than traditional ones, which actually enhances the fudgy quality we're after.
Bake to Perfect Fudgy Texture
Preheat your oven to 350°F and line a 9x13-inch baking pan with parchment paper, leaving an overhang on the sides for easy removal. Spread the batter evenly into the prepared pan, smoothing the top with a spatula. Bake for 25-30 minutes, until the edges are set but the center still appears slightly underdone.
This is where patience pays off—don't overbake. The brownies will continue cooking slightly as they cool. You'll know they're done when a toothpick inserted in the center comes out with a few moist crumbs but no wet batter. The top should be crackly but not completely dry. For even baking, rotate the pan halfway through the cooking time if your oven has hot spots.
Finish and Serve
Remove the brownies from the oven and let them cool completely in the pan on a wire rack for at least 1 hour. This cooling time is essential—it allows the flavors to meld and the texture to set properly. While they cool, you can dust the top with 0.25 cup powdered sugar if desired, using a fine-mesh sieve for an even finish.
Once fully cooled, use the parchment overhang to lift the brownies out of the pan. Cut into 12 equal squares using a sharp knife dipped in hot water and wiped clean between cuts. Serve at room temperature for the best texture—they'll be rich, fudgy, and packed with peanut butter-chocolate flavor in every bite. Store leftovers in an airtight container at room temperature for up to 5 days.
Pro Tips For Making Black Bean Peanut Butter Brownie
- BLEND BEANS SMOOTH: Mix the black beans with a splash of hot water (about 2 tablespoons) before blending—they’ll purée silky instead of grainy, and your brownie won’t taste like you’re eating bean soup. (Yes, even if you’re impatient like me, take the 30 seconds to do this.)
- STIR PEANUT BUTTER FIRST: Warm the peanut butter in the microwave for 10-15 seconds before mixing it in—it’ll fold into the batter like butter, not clumps. Cold peanut butter makes for dense, chewy brownies that taste like they’re fighting for their life.
- DON’T OVERMIX THE BATTER: Once you add the flour, stir just until combined—lumpy is better than tough. I learned this the hard way after making a batch that could’ve been used as a doorstop. Keep it loose.
- FOLD CHOCOLATE LAST: Add the dark chocolate chips right before pouring the batter into the pan—this keeps them melty and gooey, not scattered like confetti. If you’re really short on time, microwave the chips for 10 seconds first to soften them up.
Pro cooking tips for great black bean peanut butter brownie
Black Bean Blending
Blend the black beans until completely smooth—this is your secret weapon for moisture and protein. Use a high-powered food processor like the Ninja BN601 for best results, pulsing until the texture resembles thick hummus. Any visible chunks will create a gritty texture in your brownies.
I find warming the beans slightly (30 seconds in the microwave) helps them blend more smoothly and reduces the need for extra liquid later. 🥜
Peanut Butter Prep
Warm your peanut butter for 30 seconds in the microwave before mixing—this transforms it from thick to spreadable, making it blend seamlessly with the applesauce. I recommend Smucker's Natural peanut butter for its creamy consistency without added sugars.
If you prefer extra peanut flavor, reserve 2 tablespoons to fold in at the end, creating beautiful swirls throughout each brownie.
Batter Consistency
The batter should be thick but pourable—similar to traditional brownie batter. If it looks too stiff, add 1 tablespoon of water at a time until it reaches the right consistency. The black beans provide moisture, but their exact hydration level can vary by brand.
Trust the process: these brownies will be denser than traditional ones, which actually enhances their fudgy quality. Don't be tempted to add extra flour—it will make them dry. 💫
Chocolate Integration
Fold in the chocolate chips gently to maintain pockets of gooey goodness. I like to use Valrhona Guanaja 70% chocolate chips for their rich, complex flavor. If you're using chopped chocolate bars, melt them slightly first by placing the bowl over a pot of simmering water for 2 minutes.
This creates a smoother texture throughout the brownies without overmixing.
Baking Precision
Bake at 350°F for 25-30 minutes—the edges should be set while the center remains slightly underdone. This is where patience pays off. Overbaking will dry out the brownies, ruining their fudgy texture.
Rotate the pan halfway through if your oven has hot spots. The toothpick test is your best friend: it should come out with moist crumbs, not wet batter. ⏰
Cooling Technique
Let the brownies cool completely in the pan for at least 1 hour before cutting. This cooling time allows the flavors to meld and the texture to set properly. The longer they cool, the more intense the peanut-chocolate flavor becomes.
For extra presentation, dust with powdered sugar using a fine-mesh sieve just before serving. The contrast between the crackly top and fudgy interior is what makes these brownies truly special. 🍫
Nutrition facts
Frequently asked questions
Why do these brownies use black beans?
Black beans act as a natural egg substitute, providing moisture and protein while keeping the texture dense and fudgy. They also replace butter/oil for a lighter option without sacrificing richness. The flavor is neutral when blended smooth, so you only taste the peanut butter and chocolate.
Can I make these gluten-free?
Replace the all-purpose flour with a 1:1 gluten-free blend like Bob's Red Mill. The black beans and peanut butter already make these naturally gluten-free, so no other adjustments are needed. Just ensure your chocolate chips are certified gluten-free too.
What if my brownies turn out too dense?
This recipe is designed to be denser than traditional brownies—the black beans create a fudgy texture that's actually desirable! If yours seem too heavy, try baking for 23-25 minutes instead of 30 minutes next time. The key is underbaking slightly for maximum moisture.
How do I store leftovers?
Keep brownies in an airtight container at room temperature for up to 5 days. For longer storage, wrap individually in parchment paper and freeze for 3 months. Thaw at room temperature for 1-2 hours before serving. The texture remains perfect when stored properly!
Can I add other nut butters?
Yes! Swap peanut butter for almond, cashew, or tahini (1:1 ratio), but taste may vary. Tahini adds a sesame note, while almond butter gives a lighter flavor. For best results, use natural, unsweetened varieties. The texture will change slightly depending on the fat content of your nut butter.
