These black bean brownies are surprisingly rich and fudgy despite being lower in fat than a traditional brownie. The pureed black beans add fiber and some protein while keeping the texture dense and moist — and the chocolate hides the bean flavor so well that most people never suspect they’re in there.
If you want to reduce the sugar and points even further, try using a reduced-sugar boxed brownie mix; I originally calculated nutrition using a standard box of Pillsbury Chocolate Fudge Brownies and plan to test a reduced-sugar version to compare. Nutrition and points will vary depending on the brand of mix you use and how you portion the brownies.
Black Bean Brownies
Yield: 20 servings
Serving Size: 1 brownie
WW Personal Points (example): 5 (calculated with a specific boxed mix)
Calories per serving: 138.1 kcal
Protein: 2.9 g • Carbs: 28 g • Fat: 2.6 g • Fiber: 1.8 g
Ingredients
- 15 oz can black beans, drained and rinsed
- 19.5 oz box chocolate brownie mix (use reduced-sugar if preferred)
Instructions
- Open the can of black beans, drain and rinse them thoroughly under cold water.
- Return the beans to the empty can (or a measuring cup) and fill the same can with water to roughly match the liquid called for on the brownie mix package. Pour the water and beans into a blender or food processor.
- Blend until completely smooth, scraping down the sides as needed so no bean chunks remain. The pureed beans should resemble a thin batter.
- Pour the pureed beans into a mixing bowl and add the boxed brownie mix. Stir until well combined. Do not add the eggs or oil called for on the box — the beans replace those ingredients.
- Prepare a baking dish by spraying lightly with cooking spray. Spread the batter evenly in the pan.
- Bake the brownies according to the package directions for a similar-sized pan and portion, checking a few minutes early since oven temperatures vary. A toothpick inserted into the center should come out with moist crumbs but not wet batter.
- Allow the brownies to cool completely before cutting into 20 equal pieces for even portions. Cool time helps the texture set and yields cleaner slices.
Nutrition (per serving)
Serving: 1 brownie — Calories: 138.1 kcal; Carbohydrates: 28 g; Protein: 2.9 g; Fat: 2.6 g; Fiber: 1.8 g. These values are based on the calculation using a specific boxed brownie mix; your numbers will change depending on the mix you choose and any optional add-ins.
Tips for Success
- Blend the beans until very smooth. Any lumps can affect the final texture and may make slices less uniform.
- Use the can method to estimate the water amount quickly: after emptying the beans back into the can, fill it with water and pour into the blender for a convenient liquid measure.
- Do not add the eggs or oil called for on the boxed mix — the pureed beans provide moisture and structure. Adding eggs or oil will change the calorie and fat profile and alter the intended texture.
- To test doneness, insert a toothpick in the center. You want moist crumbs on the pick rather than wet batter; overbaking will dry them out.
- Let the brownies cool completely before cutting. They firm up as they cool, which makes cleaner slices and a fudgier texture.
Variations and Serving Ideas
These brownies are a flexible base for simple variations: fold in a handful of dark chocolate chips for extra chocolate intensity, sprinkle a few chopped nuts on top before baking for crunch, or dust with powdered sugar after cooling. Serve warm with a scoop of low-fat vanilla ice cream or plain Greek yogurt for an easy dessert. For a lower-sugar option, substitute a reduced-sugar boxed mix or choose a mix labeled for fewer calories.
Storage
Store cooled brownies in an airtight container at room temperature for a day or two. To extend freshness, refrigerate them; bring to room temperature or warm briefly before serving for the best texture. You can also freeze individual brownies wrapped tightly for longer storage—thaw in the refrigerator or at room temperature.
Final Notes
These black bean brownies are an easy, budget-friendly way to enjoy a fudgy chocolate treat while adding a boost of fiber and plant-based protein. They are perfect for potlucks, school snacks, or when you want a lighter take on a classic brownie. Experiment with different boxed mixes and add-ins to find the version you like best.
