Ingredients

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

1½ cups granulated sugar
½ cup neutral oil (such as canola or vegetable oil)
1 tablespoon vanilla extract
2 cups all-purpose flour
⅓ cup unsweetened cocoa powder
1 teaspoon salt
1½ teaspoons baking soda
¼ teaspoon baking powder
2 cups finely shredded zucchini (with natural moisture included)
2 cups semi-sweet chocolate chips, divided

Directions

1. Prepare the pan:

   • Spray a 9x13-inch metal baking dish with non-stick spray.

   • Preheat oven to 350°F (175°C).

2. Mix wet ingredients:

   • In a large mixing bowl, whisk together the granulated sugar, oil, and vanilla extract until combined.

3. Add dry ingredients:

   • Stir in the flour, cocoa powder, salt, baking soda, and baking powder.

   • Mix until just barely combined (batter will look dry at this stage).

4. Add zucchini:

   • Stir in the shredded zucchini with all of its moisture.

   • Let the batter sit for 2 minutes to allow the zucchini to release additional moisture.

5. Fold in chocolate chips:

   • Add 1½ cups of the chocolate chips to the batter and stir again until fully combined.

6. Bake:

   • Spread the batter evenly into the prepared baking dish.

   • Sprinkle the remaining ½ cup of chocolate chips over the top.

   • Bake for 27–32 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.

7. Cool completely:

   • Allow brownies to cool in the pan on a wire rack for at least 20 minutes before cutting.

   • They will fall apart if sliced while hot.

FAQs

Can I taste the zucchini in these brownies?

No, the zucchini melts into the batter and is virtually undetectable in both flavor and texture.

Do I need to peel the zucchini?

No, there’s no need to peel it—just finely shred it and leave the peel on for extra fiber and color.

Should I squeeze out the moisture from the zucchini?

No, use the zucchini as-is with its natural moisture. It helps keep the brownies fudgy.

Can I use a glass baking dish?

A metal baking dish is recommended for even baking and better texture. If using glass, you may need to add a few extra minutes to the baking time.

Can I reduce the sugar?

Yes, you can reduce the sugar by ¼ to ½ cup, but the texture and sweetness will be affected.

How do I know when the brownies are done?

They’re done when a toothpick inserted in the center comes out with moist crumbs but no wet batter.

Can I make this recipe vegan?

Yes, just be sure to use vegan sugar and dairy-free chocolate chips.

Can I add cocoa powder for a darker brownie?

You can increase the cocoa to ½ cup for a more intense chocolate flavor, but the texture will be slightly drier.

What type of chocolate chips should I use?

Semi-sweet chocolate chips work best, but you can also use dark, milk, or vegan chocolate chips.

Are these brownies freezer-friendly?

Absolutely. They freeze well for up to 2 months—perfect for make-ahead treats.
