Ingredients:

  • 1/2 cup (115g) unsalted butter, melted
  • 3/4 cup (150g) brown sugar, packed
  • 1 large egg, room temperature
  • 1 tsp (5ml) vanilla extract
  • 1 1/2 cups (150g) zucchini, finely shredded
  • 1/2 cup (45g) unsweetened cocoa powder
  • 1/2 cup (65g) all-purpose flour
  • 1/4 tsp (1.5g) salt
  • 1/2 tsp (2g) baking powder
  • 1/2 cup (85g) semi-sweet chocolate chips

Instructions:

  1. Preheat oven to 350°F (175°C) and line an 8x8 inch baking pan with parchment paper.
  2. Finely shred the zucchini using the fine side of a box grater to ensure the pieces melt into the batter.
  3. Whisk melted butter and brown sugar until smooth, then stir in the egg and vanilla until glossy.
  4. Fold in the shredded zucchini.
  5. Sift in cocoa powder, flour, salt, and baking powder; stir until no streaks of flour remain.
  6. Fold in the semi-sweet chocolate chips.
  7. Let the batter rest for five minutes to allow dry ingredients to hydrate.
  8. Spread batter evenly into the prepared pan and bake for 30–35 minutes until edges are set and center has a slight jiggle.
  9. Cool completely in the pan before slicing to allow the fudgy structure to set.
