Description

These moist and fudgy Zucchini Brownies combine the richness of chocolate with the subtle moisture and nutrition of shredded zucchini. Perfect for a healthier twist on a classic dessert, they feature a tender crumb, melty chocolate chunks, and a deep cocoa flavor with an easy-to-follow recipe ideal for any baking level.


Ingredients

Wet Ingredients

  • ½ cup (112 g) vegetable oil
  • 1 ½ cups (300 g) granulated sugar
  • 1 tablespoon vanilla extract

Dry Ingredients

  • 2 cups (256 g) all-purpose flour
  • ½ cup (64 g) unsweetened cocoa powder
  • 1 ½ teaspoon baking soda
  • 1 teaspoon kosher salt

Additional Ingredients

  • 3 cups finely shredded zucchini (DO NOT DRAIN)
  • 1 ¼ cups semi-sweet chocolate chunks


Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Prepare a 9×13 inch baking pan by greasing with butter or using baking spray, then line it with parchment paper ensuring the paper extends up the sides for easy brownie removal.
  2. Mix Wet Ingredients: In a large mixing bowl, combine the vegetable oil, granulated sugar, and vanilla extract. Mix thoroughly until the ingredients are well incorporated and smooth.
  3. Add Dry Ingredients: To the wet mixture, add the all-purpose flour, unsweetened cocoa powder, baking soda, and kosher salt. Stir until just combined. The batter at this stage will look very dry.
  4. Fold In Zucchini: Gently fold the finely shredded zucchini into the dry batter by hand to incorporate the moisture evenly. Allow the batter to rest for 5 minutes, which helps hydrate the dry ingredients and results in a better texture.
  5. Add Chocolate Chunks: Stir in the semi-sweet chocolate chunks. After adding, the batter should become noticeably more moist and wet. If it still seems dry, let it rest for an additional 5 minutes before stirring again to achieve the right consistency.
  6. Bake the Brownies: Spread the batter evenly into your prepared pan. Bake in the preheated oven for 25 to 35 minutes. Check doneness by inserting a toothpick in the center; it should come out with moist crumbs but no wet batter.

Notes

  • Do not drain the shredded zucchini; its moisture is essential for the fudgy texture.
  • Letting the batter rest twice allows the dry ingredients to absorb moisture, improving the final texture.
  • Use parchment paper for easy removal of brownies once baked.
  • Check brownies at 25 minutes to avoid overbaking; the toothpick test with moist crumbs is the best indicator.
  • You can substitute vegetable oil with canola or light olive oil for a different flavor profile.
