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:
- Preheat oven to 350°F (175°C). Line an 8x8 inch baking pan with parchment paper, leaving an overhang on the sides.
- 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.
- In a large bowl, whisk together the melted butter and granulated sugar until combined.
- Add the eggs and vanilla extract to the butter mixture, beating until the batter looks glossy.
- Stir in the squeezed zucchini until evenly distributed.
- 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.
- Fold in the semi-sweet chocolate chips and chopped walnuts.
- 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.
