What You Need to Make Zucchini Brownies

When you’re making a classic brownie with added grated zucchini you don’t need anything special. Whew, no surprise ingredients needed.

  • butter
  • granulated sugar
  • vanilla extract or try vanilla bean paste for an extra boost of flavor!
  • all-purpose flour
  • cocoa powder
  • baking soda
  • salt
  • shredded zucchini, peeled or unpeeled?? see notes below!
  • chocolate chips
  • milk
  • powdered sugar
  • 8×8 baking pan (or you can use a 9×9 baking pan)

Peeled or unpeeled for zucchini brownies

If you have a super picky eater you can absolutely peel the zucchinis. BUT you don’t necessarily need to peel them, typically you don’t see a lot of peel in chocolatey recipes. Sometimes you’ll see a piece but not often. And if that’s going to bother someone peel them up. Otherwise, skip it!

Abundant Zucchini!

If you’ve ever grown zucchini in your garden, you know how abundant the harvest can be. It’s a common scenario: you check your zucchini plant every day, and suddenly on day, there’s an armful of zucchini that needs to be used up ASAP. But fret not, because zucchini brownies might be the solution you’ve been looking for.

Use Up All That Zucchini

Zucchini brownies are a fantastic way to put all those zucchini to good use. These brownies add a mild flavor and a moisture-rich element to your baked goods. The shredded zucchini effortlessly blends into the brownie batter, making it a perfect dessert for those who enjoy fudgy brownies with a tiny touch of nutritional value.

If you have even more zucchini than you can handle, consider freezing them for later use in recipes like zucchini brownies. Read up on freezing zucchini in my tips and tricks post, and you can enjoy all the zucchini recipes all year long.

Shredding Zucchini

When it comes to making zucchini brownies, a food processor isn’t necessary you can use a box grater. But it is NICE to have one for shredding a lot of zucchini. If you’re going to shred a bunch of zucchini and freeze it, please read my post about freezing zucchini. There’s a lot of great information in that post to help you put up your harvest!
