Tips for recipe success

This healthy brownie recipe is really quite easy, and here are our TOP tips for making sure it turns out perfect!

  • It’s best to use the small side of your grater so that you get smaller shreds of zucchini. No one will be able to tell there’s zucchini in this treat!
  • Squeeze out your zucchini shreds as much as possible using your hands, a cheesecloth, a clean dish towel, or a paper towel to get all of the excess liquid out. This is important so that the brownies have the right texture.
  • If you know you’ll be doing more baking with zucchini, you can shred a bunch at one time and freeze it for later!
  • Cool completely. It’s tough waiting for these soft, chewy, chocolatey babies to cool, but it will be worth the wait. They will slice up perfectly when cooled completely.

Frequently asked questions

How healthy is zucchini brownie?

Not all zucchini brownies are created equal. This particular recipe is made healthier by using nutrient-rich ingredients. They are high in fiber and contain many vitamins and antioxidants.

What does zucchini replace in baking?

Surprisingly, zucchini replaces the oil! We only need 1/4 cup oil in this zucchini brownies recipe because the shredded zucchini adds so much moistness.

Why do people add zucchini to cake?

Zucchini is an excellent ingredient to add to baked goods because it replaces some of the fat. This makes your dessert lower in calories and higher in nutrition, while also adding great texture and a boost of nutrients. A great thing about adding zucchini to sweet baked goods is it has a mild flavor and you can’t taste it!
