Healthy Fudgy Peanut Butter Swirled Black Bean Brownies

Servings: 9 brownies
Prep Time: 30 minutes
Cook Time: 55 minutes
Total Time: 1 hour 30 minutes
Super moist and secretly healthy, ULTRA FUDGY Peanut Butter Swirled Black Bean Brownies! Low fat, sugar free, high fiber, high protein, gluten free and vegan!


  • 20g (3 tbs) Ground Flaxseed
  • cup Unsweetened Vanilla Almond Milk
  • 156g (¾ cup + 1 tbs) Granulated Erythritol (or dry sweetener of choice)
  • 60g (¾ cup) Unsweetened Natural Cocoa Powder
  • 34g (¼ cup) Quinoa Flour
  • tsp Double-Acting Baking Powder
  • ½ tsp Baking Soda
  • ¼ tsp Instant Coffee
  • tsp Salt
  • ½ cup + 1 tbs Fresh Blueberry Puree (see Instructions)
  • 1 15.5oz can Black Beans (drained and rinsed well!)
  • 14g (1 tbs) Grapeseed Oil (or any other neutral oil)
  • 1 tsp Vanilla Extract
  • 64g (¼ cup) Natural Peanut Butter
  • ¼ tsp Salt


  • Preheat your oven to 350 degrees Fahrenheit and spray an 8" brownie pan with cooking spray, set aside.
  • In a small bowl, stir together the flax and almond milk, set aside to gel up.
  • In a large mixing bowl, whisk together the erythritol, cocoa powder, quinoa flour, baking powder, baking soda, instant coffee and salt.
  • In a blender, puree blueberries and measure 1/2 cup + 1 tbs. Remove any leftover puree from the blender and add the 1/2 cup + 1 tbs back in. Add the beans, oil, vanilla extract and flax gel and puree until smooth.
  • In a small microwave-safe bowl, stir together the peanut butter and salt and microwave for 20 seconds, or until warm.
  • Pour the dry over the wet and fold together (batter should be thick). Scoop into the prepared pan and drizzle the warmed PB mixture over the brownie batter in lines. Make swirls by dragging a knife the opposite way of the PB lines.
  • Bake for ~55 minutes, or until surface is firm when tapped. Let cool in the pan for ~30 minutes, then transfer to a wire cooling rack. Slice when completely cool (I sliced them the same day, but they were somewhat delicate so I recommend covering the brownies with plastic wrap, leave them overnight and slice them the next day)

Recipe Notes

Feel free to fold in some chocolate chips or your favorite nuts!
