Ingredients

  • 1 cup black beans canned, rinsed and drained very well
  • ¾ cup zucchini finely grated, lightly squeezed to remove excess moisture
  • 1 large egg
  • ¼ cup melted butter or neutral oil
  • ⅓ cup maple syrup or sugar-free maple syrup
  • 1 tsp vanilla extract
  • ½ cup cocoa powder unsweetened
  • ¼ tsp salt
  • ½ tsp baking powder
  • ⅓ cup dark chocolate chips optional

Equipment

  • Blender or food processor
  • Mixing bowl
  • Box grater
  • 8×8 baking pan

Instructions

  • Preheat oven to 350°F (175°C). Line an 8×8 baking pan with parchment paper.
  • Grate the zucchini and gently squeeze it in a clean towel or paper towel to remove excess water. Set aside.
    ¾ cup zucchini
  • In a blender or food processor, blend the black beans, egg, melted butter, maple syrup, and vanilla until completely smooth.
    1 cup black beans, 1 large egg, ¼ cup melted butter, ⅓ cup maple syrup, 1 tsp vanilla extract
  • Transfer the mixture to a bowl and stir in cocoa powder, salt, and baking powder until fully combined.
    ½ cup cocoa powder, ¼ tsp salt, ½ tsp baking powder
  • Fold in the grated zucchini and chocolate chips.
    ⅓ cup dark chocolate chips
  • Spread the batter evenly in the prepared pan.
  • Bake for 18–22 minutes, until the edges are set and the centre is just slightly soft.
  • Let the brownies cool completely before slicing — this helps them firm up.

Cooking Tips

  • Smooth Batter: Blend the bean mixture thoroughly so the brownies have a smooth, traditional brownie texture.
  • Moisture Control: Lightly squeeze the grated zucchini to prevent excess water from making the batter too wet.
  • Even Spreading: Use a spatula to spread the batter evenly in the pan for consistent baking.
  • Cooling Time: Allow brownies to cool completely before slicing so they set properly.
  • Chocolate Boost: Use high-quality dark chocolate chips for deeper chocolate flavour.
  • Clean Slicing: Use a warm knife to cut cleaner brownie squares.
