Instructions: How to Make Zucchini Brownies
Step 1: Prepare Your Zucchini
Wash and trim the zucchini. Using a box grater or food processor, shred the zucchini finely. Place shredded zucchini in a clean kitchen towel and squeeze out excess moisture. This prevents soggy chocolate zucchini bars.
Step 2: Preheat and Prep
Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper or grease with butter. This ensures your zucchini dessert recipes turn out perfectly every time.
Step 3: Mix Wet Ingredients
In a large mixing bowl, combine melted butter, vegetable oil, and granulated sugar. Whisk until smooth. Add eggs one at a time, then vanilla extract. Fold in the prepared shredded zucchini.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together flour, cocoa powder, baking powder, and salt. This creates the perfect base for your easy zucchini brownies.
Step 5: Create the Batter
Gradually add the dry ingredients to the wet mixture. Stir just until combined. Don’t overmix, as this can make your moist zucchini brownies tough. Fold in chocolate chips if using.
Step 6: Bake to Perfection
Pour batter into your prepared pan and spread evenly. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. These zucchini bars should feel set but still slightly soft.
Step 7: Cool and Serve
Allow the brownies to cool completely in the pan before cutting. This helps them hold their shape and develop the perfect fudgy texture.
Pro Tips and Variations
Professional Secrets:

FAQs
Can I taste the zucchini in these zucchini brownies?
No! When prepared correctly, the zucchini adds moisture without any vegetable flavor. The chocolate completely masks any zucchini taste.
How much zucchini do I need for this recipe?
One medium zucchini (about 6-8 inches long) yields approximately 1 cup of shredded zucchini after squeezing out excess moisture.
Can I make these zucchini brownies ahead of time?
Absolutely! These actually taste better the next day as flavors meld together. Store covered for up to 5 days or freeze for longer storage.
What’s the difference between zucchini bars and zucchini brownies?
The terms are often used interchangeably. Both refer to bar-shaped desserts made with zucchini, though some zucchini bars recipes include frosting.
Can I double this recipe?
Yes! Double all ingredients and use two 9×13 pans, or bake in a large sheet pan, adjusting baking time as needed.
Are these zucchini brownies healthy?
While still a dessert, they’re healthier than traditional brownies due to added vegetables, reduced oil content, and the option to use whole wheat flour or reduce sugar.
Can I use yellow squash instead of zucchini?

Why are my zucchini brownies soggy?
This usually happens when you skip squeezing moisture from the shredded zucchini. Always drain excess water before adding zucchini to your batter.
