Ingredients

Scale
  • 1 cup (120 g) all-purpose flour
  • 3/4 cup (75 g) unsweetened cocoa powder (Dutch-processed recommended)
  • 1 tsp baking powder
  • 1/2 tsp salt
  • 3/4 cup (150 g) granulated sugar
  • 1/4 cup (50 g) packed brown sugar
  • 1/2 cup (120 ml) vegetable oil
  • 2 large eggs, room temperature
  • 1 tsp vanilla extract
  • 1 1/2 cups grated zucchini (about 1 medium zucchini, squeezed to remove excess water)
  • 3/4 cup (130 g) semi-sweet chocolate chips
  • 1 tsp espresso powder (optional)

Instructions

  1. Prepare the zucchini: Wash and trim a medium zucchini. Grate finely using a box grater. Place grated zucchini in a clean kitchen towel or paper towels and squeeze out as much moisture as possible. (About 10 minutes)
  2. Preheat oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving an overhang on two sides for easy removal.
  3. Mix dry ingredients: In a large bowl, whisk together flour, cocoa powder, baking powder, salt, and espresso powder if using. Break up any lumps. (5 minutes)
  4. Add sugars: Stir in granulated sugar and brown sugar to the dry mix.
  5. Combine wet ingredients: Add vegetable oil, eggs, and vanilla extract to the dry ingredients. Gently fold with a rubber spatula until mostly combined. Avoid overmixing. (5 minutes)
  6. Fold in zucchini and chocolate chips: Carefully incorporate the squeezed zucchini and chocolate chips into the batter. (3 minutes)
  7. Transfer and smooth: Pour batter into prepared pan and smooth the surface with a spatula.
  8. Bake: Bake for 25-30 minutes. Start checking at 25 minutes by inserting a toothpick in the center; it should come out with a few moist crumbs but no wet batter.
  9. Cool properly: Remove from oven and cool in pan on a rack for at least 20 minutes. Use parchment overhang to lift brownies out and cool completely before slicing.

Notes

Squeeze zucchini thoroughly to avoid soggy brownies. Use room temperature eggs for better batter texture. Avoid overmixing to keep brownies tender. Start checking doneness early to prevent drying out. Espresso powder enhances chocolate flavor without adding coffee taste. Chill brownies before slicing for cleaner cuts. If zucchini is very watery, add 1-2 tablespoons of flour to the batter.
