Rich, dense, maple-sweetened brownies made with no flour at all. Naturally gluten-free, fudgy, and easy to make in one bowl.
These fudgy black bean brownies come together in one bowl with pure maple syrup, cocoa, and no flour. They are gluten-free, freezer-friendly, and rich enough for dessert while still getting a boost from beans.
Prep Time: 10 minutes (Quick blend‑and‑pour batter)
Cook Time: 22–28 minutes (Depends on how fudgy you like them)
Total Time” 35–40 minutes
Servings: 9 brownies (cut 3×3 in an 8×8 pan) or 12 smaller squares
Ingredients
- 1 can (15 oz) black beans, drained and rinsed very well
- 3 large eggs
- ½ cup pure maple syrup
- ¼ cup melted butter or coconut oil
- ⅓ cup cocoa powder
- 1 tsp vanilla
- ½ tsp baking powder
- ¼ tsp salt
- Optional: ½ cup chocolate chips
- Optional: 2 tbsp maple sugar for extra maple punch
Instructions
- Preheat oven to 350°F. Grease an 8X8 pan or line with parchment.
- In a blender or food processor, blend beans, eggs, maple skyrup, melted butter, vanilla, and salt until completely smooth.
- Add Cocoa powder and bakning powder; blend again until thick and glossy.
- Stir in chocolate chips if using.
- Pour into the pan and smooth the top.
- Bank 22-28 minutes, until the center is set but still soft and a toothpick inserted near the center comes out with moist crumbs.
- Cool at least 15 minutes – they firm up as they rest.
- For extra maple goodness, dust the top with maple sugar while warm.
Notes
- These are fudgy, not cakey — almost like a maple brownie truffle.
- If you want them sweeter, add 2–3 tbsp brown sugar or maple sugar.
- They freeze beautifully.
- A swirl of peanut butter or maple cream on top before baking is incredible.
- Store brownies in an airtight continer at room temperature for up to 2 days, refrigerate for up to 5 days or freeze for up to 3 months.
- You can get pure maple syrup from Presby’s Maple Farm LLC.
- For a dairy-free version, use coconut oil instead of butter and choose dairy-free chocolate chips if adding them.
