Ingredients:

  • 1/2 cup (115g) unsalted butter, melted
  • 1 cup (200g) granulated sugar
  • 2 large eggs
  • 1 tsp (5ml) vanilla extract
  • 1 1/2 cups (170g) finely shredded zucchini, squeezed dry
  • 1/2 cup (65g) all-purpose flour
  • 1/2 cup (45g) unsweetened cocoa powder
  • 1/2 tsp (3g) baking soda
  • 1/4 tsp (1.5g) salt
  • 3/4 cup (130g) semi-sweet chocolate chips
  • 1/2 cup (60g) chopped walnuts

Instructions:

  1. Preheat oven to 350°F (175°C). Line an 8x8 inch baking pan with parchment paper, leaving an overhang on the sides.
  2. Grate the zucchini using the fine side of a grater, place the shreds in a clean kitchen towel, and squeeze firmly to remove excess water.
  3. In a large bowl, whisk together the melted butter and granulated sugar until combined.
  4. Add the eggs and vanilla extract to the butter mixture, beating until the batter looks glossy.
  5. Stir in the squeezed zucchini until evenly distributed.
  6. Sift in the all-purpose flour, cocoa powder, baking soda, and salt. Fold the ingredients together with a silicone spatula just until no streaks of flour remain.
  7. Fold in the semi-sweet chocolate chips and chopped walnuts.
  8. Spread the batter evenly into the prepared pan and bake for 25–30 minutes, until the edges are firm and slightly pulled away from the pan, but the center still has a slight jiggle.
