Ingredients & Substitutions
Black Beans
You will need 1 can (15 oz / 425g) of black beans for the base of this recipe. Thoroughly rinsing and draining them is crucial to remove any canned starch and lingering savory flavors.
Dutch-Processed Cocoa Powder
Using 1/2 cup (50g) of high-quality Dutch-processed cocoa powder delivers a deep, dark chocolate interior. Standard unsweetened cocoa powder works, but the color and flavor won’t be as intensely rich.
Granulated Sugar & Maple Syrup
A blend of 1/2 cup (100g) granulated sugar and 1/4 cup (60ml) pure maple syrup provides the perfect sweetness and moisture. The granulated sugar is the scientific secret to achieving that beautiful crinkled top edge.
Eggs
You need 2 large eggs (about 100g total) to provide structure, lift, and binding. They aerate the batter just enough to keep the brownies fudgy rather than gummy.
Coconut Oil
Adding 1/4 cup (60ml) of melted coconut oil gives the brownies a luxurious mouthfeel and replaces traditional butter. You can easily substitute this with an equal amount of melted unsalted butter if preferred.
Baking Powder & Fine Salt
Use 1/2 tsp (2g) of baking powder to give the dense batter a slight lift, preventing it from becoming a solid brick. We also add 1/4 tsp (1g) of fine sea salt into the batter to balance the bitterness of the cocoa.
Vanilla Extract
Incorporate 1 tsp (5ml) of pure vanilla extract to round out the flavor profile. Vanilla naturally amplifies the perceived sweetness and depth of the chocolate.
Semi-Sweet Chocolate Chips
You will need 1/2 cup (85g) of semi-sweet chocolate chips, divided. Half goes into the batter, and half is studded on top for those glossy, partially melted visual cues.
Coarse Flaky Sea Salt
Keep 1 tsp (3g) of coarse flaky sea salt on hand for finishing. Sprinkling this over the warm, melted chocolate chips creates a stunning bakery-style presentation.
Equipment Needed
- High-speed food processor or powerful blender (essential for a perfectly smooth batter)
- 8×8-inch (20x20cm) square baking pan
- Unbleached crinkled parchment paper
- Rubber spatula
Step-by-Step Instructions
Step 1: Prep Your Pan and Oven
Preheat your oven to 350°F (175°C). Line an 8×8-inch (20x20cm) baking pan with unbleached parchment paper, leaving an overhang on the sides for easy removal. Lightly grease the parchment to ensure the fudgy edges don’t stick.
Step 2: Rinse and Drain the Beans
Pour the black beans into a fine-mesh sieve and rinse them under cold water for at least 60 seconds. Shake off as much excess water as possible. This removes the savory canning liquid so your brownies taste purely like dark chocolate.
Step 3: Blend the Batter
In your food processor, combine the rinsed black beans, cocoa powder, granulated sugar, maple syrup, eggs, melted coconut oil, baking powder, fine salt, and vanilla extract. Process on high for 3 to 4 minutes.
Step 4: Check for Smoothness
Stop the processor and scrape down the sides with a rubber spatula. Continue blending until the batter is completely smooth, velvety, and shows absolutely no chunks of beans. The smoother the batter, the fudgier your brownies will be.
Step 5: Fold in the Chocolate
Remove the processor blade carefully. Gently fold in half of the semi-sweet chocolate chips—about 1/4 cup (42g)—using your rubber spatula. This ensures pockets of melted chocolate inside the dense interior.
Step 6: Pour and Top
Pour the thick batter into your prepared baking pan, spreading it out evenly into the corners. Evenly stud the top of the batter with the remaining 1/4 cup (42g) of semi-sweet chocolate chips.
Step 7: Bake to Perfection
Bake on the center rack for 22 to 26 minutes. Look for visual cues: the edges should have a very slightly crinkled top, and the center should look set but still slightly soft. Do not overbake, or you will lose the dense, fudgy texture.
Step 8: Garnish and Cool
Remove the pan from the oven. While the chocolate chips on top are glossy and partially melted, immediately sprinkle the coarse flaky sea salt evenly across the surface. Let the brownies cool completely in the pan before lifting them out using the parchment overhang.
Expert Tips for Success
- Rinse aggressively: Do not skip rinsing the beans. The cleaner the beans, the more neutral their flavor profile will be, letting the cocoa shine.
- Blend longer than you think: To avoid a grainy texture, process the batter until it looks exactly like traditional, velvety brownie batter.
- Don’t skip the sugar: While it’s tempting to use only liquid sweeteners, the granulated sugar is scientifically required to form the signature crinkled top edge.
- Cool completely: Because these brownies are flourless and incredibly fudgy, they need time to set up as they cool. Slicing them while hot will result in a messy, falling-apart square.
- Use a hot knife: For perfectly clean squares to stack on your rustic white ceramic plate, run a sharp chef’s knife under hot water, wipe it dry, and slice.
Storage & Reheating
Store any leftover brownies in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week. Keeping them in the fridge makes them even denser and fudgier.
To freeze, wrap individual squares in plastic wrap and place them in a freezer-safe bag for up to 3 months. Thaw overnight in the refrigerator or microwave for 15 seconds to return the chocolate chips to a glossy, melted state.
What to Serve With This
These decadent squares are the perfect sweet finish to almost any meal. Serve them after a comforting, savory dinner like our rich classic beef stew or a flavorful jamaican brown stew chicken.
If you’re hosting a dessert spread, these brownies pair beautifully alongside our strawberry matcha marble cookies and chocolate peanut butter snowballs. For the ultimate cozy night in, serve a brownie square warm next to a steaming mug of french hot chocolate.
Frequently Asked Questions
Yes! Because the pureed black beans replace traditional flour entirely, these brownies are naturally gluten-free. Just ensure your brand of chocolate chips and baking powder are certified gluten-free.
Yes, but you must cook them completely from scratch until they are extremely tender before measuring out 1.5 cups (about 250g) to substitute for one 15 oz can. Canned beans are recommended for convenience and consistent moisture.
Not at all! As long as you thoroughly rinse and drain the canned black beans before blending, the robust flavor of the Dutch-processed cocoa powder and semi-sweet chocolate chips completely masks any bean flavor.
A crinkly top requires the proper ratio of sugar and eggs. If you substitute the granulated sugar entirely with a liquid sweetener like maple syrup or omit the eggs, you will lose the delicate, slightly crinkled top edge.
A grainy batter means the food processor wasn’t run long enough. You need a high-speed processor or blender, and you must blend the wet ingredients for a full 3 to 4 minutes until perfectly smooth and velvety.
