How to Make These Irresistible Zucchini Brownies

Ready to dive into these brownies? Here’s the lowdown on how to make them, and trust me, you’re going to love it.

First Things First: Preheat the Oven

 Get your oven nice and warm by setting it to 350°F. While it heats up, grab your 9×13-inch baking dish. 

Coat it with cooking spray or opt for parchment paper to ensure easy removal. This will ensure your brownies slide out perfectly later.

Mix the Sweet Stuff Together

 Combine the granulated sugar, brown sugar, and vegetable oil in a large mixing bowl. 

Mix until the batter is perfectly smooth and gleaming. Use a stand mixer here. Then, add the vanilla extract and give it another quick mix. You’re already building that delicious base flavor.

Dry Ingredients: The Unsung Heroes

 In a separate bowl, sift together your all-purpose flour, cocoa powder, baking soda, and salt. Don’t skip the sifting step; it keeps the cocoa powder lump-free for a rich, velvety chocolate experience.

Bringing It All Together

 Add the dry ingredients to the wet ones in small portions, mixing steadily. 

Stir just until it’s combined, don’t worry if it looks a bit crumbly. This is where the zucchini comes in to save the day!

In Goes the Zucchini and Chocolate

 Toss in your shredded zucchini, yes, the secret ingredient! This is what makes the brownies moist and fudgy without anyone even realizing there’s zucchini in there. 

Mix well until the ingredients come together in a cohesive batter. Then, fold in your chocolate chips. This is when things get extra exciting because you’ll have pockets of melted chocolate throughout. Each bite delivers an unexpected burst of joy!

Into the Oven They Go

 Add your brownie mixture to the pan, making sure it’s spread out nice and level. If you’re feeling indulgent (and let’s be honest, who isn’t?), sprinkle a few extra chocolate chips on top for a little extra chocolatey love.

Baking Time: Patience, My Friend

 Put the dish in the oven and bake for 25 minutes, or until the mixture is fully set. 

You’ll know they’re done when the top looks set, dry, and slightly cracked, and the edges are pulling away from the sides. It’s okay if you’re tempted to peek, just don’t open the oven too much!

Let It Cool (If You Can Wait)

 Once they’re out of the oven, let your brownies cool for about 15 minutes. Crucial for locking in that rich, gooey consistency, this step shouldn’t be skipped. The scent is tempting, but patience will pay off!

The Zucchini Tip

Squeezing or not squeezing? It really depends on the zucchini you’re working with. If it’s a smaller, more watery zucchini, give it a light squeeze or pat it dry with a paper towel to get rid of excess moisture. 

But if it’s already on the drier side, don’t worry about squeezing, just let it do its thing. The moisture from the zucchini is what keeps your brownies soft and fudgy, so you want to keep that in!

So, trust your zucchini and don’t overdo the squeezing. A little moisture goes a long way in keeping your brownies perfectly fudgy and delicious.

4 Mistakes to Avoid

Not Grating the Zucchini Fine Enough

Make sure you grate the zucchini finely, not in big chunks! Larger pieces can make the texture uneven and affect the moisture balance in the brownies.

Finely grating it helps it integrate seamlessly with the rest of the batter.

Overmixing the Batter

Yes, it’s tempting to keep stirring, but overmixing will give you dense, cakey brownies instead of that rich, fudgy texture we’re after. 

Mix just enough until everything is combined, keep it simple!

Not Testing for Doneness

The baking time is important, but every oven is a little different. Use a toothpick to check for doneness. 

Check by inserting it in the middle; if only a few moist crumbs cling to it, they’re ready to go. If you wait for it to be completely clean, you might miss that perfect fudgy middle.

How to Store Your Zucchini Brownies

  • Room Temp- Maintain their softness by storing brownies in an airtight container on the counter for up to three days. They’ll stay fresh and fudgy, perfect for snacking all day long. 
  • Fridge- For longer-lasting goodness, keep them chilled in the refrigerator for up to seven days. The cool temps make them even richer and denser.
  • Freezer– Want to save some for later? Wrap brownies individually, pop them in a freezer bag, and freeze for up to 3 months. Thaw for a bit, and they’re good to go!

  • 1 ½ teaspoons baking soda
  • 1 teaspoon fine salt
  • 1 cup semi-sweet chocolate chips, plus extra for sprinkling on top.

Instructions

  2. In a big mixing bowl, blend together the granulated sugar, brown sugar, and vegetable oil. Mix them together until smooth and shiny. 
  3. Add the vanilla extract and mix again to bring in that sweet, delicious flavor.
  4. Combine the all-purpose flour, cocoa powder, baking soda, and salt by sifting them in a separate bowl. Sifting helps avoid any cocoa clumps, so each bite will be silky smooth and full of rich chocolate flavor.
  5. Add the dry ingredients to the wet, a little at a time, and stir until everything comes together smoothly. It might look a little crumbly, but don’t worry, this is where the zucchini works its magic!

  7. Add the batter to the baking dish and level it out for an even bake. If you're feeling extra indulgent, sprinkle a few more chocolate chips on top before baking.
  8. Bake the brownies for 25 minutes until they’re perfectly set. You’ll know they’re ready when the top looks dry and slightly cracked, with the edges starting to pull away from the sides. 
  9. Be patient, you don’t want to open the oven too much while they’re baking!
  10. Give your brownies 15 minutes to cool, then indulge in their rich flavor.

Notes

  • If you’re using larger zucchini, remember to scoop out the seeds, they can make the texture a bit off.
  • Check your brownies a little early! Every oven is different, so peek in around the 22-minute mark to avoid overbaking.
  • If you're in the mood for a little twist, add a pinch of cinnamon to the dry ingredients for a warm, comforting flavor.
