Zucchini Brownies are moist and chocolaty with a simple frosting. They also happen to be dairy-free/vegan. You’ll never know there’s zucchini hidden in them!

Zucchini Brownies

My first job was at a retirement home in the kitchen/dining room. One of my many tasks was shredding carrots for the salad bar. I hated shredding carrots. For one, it’s pretty boring. But it also turns your hands orange and is kind of messy. It was better than peeling hard boiled eggs though. 

Man, I loved that job. Old people are the best.

This recipe requires you to shred zucchini. It’s still not my favorite thing to do but at least it doesn’t stain your hands. Plus, it’s worth it. 


I went to the Farmer’s Market last weekend with my mom & brother and picked up some green beans and zucchini. I made roasted green beans & zucchini but made sure to save enough for a dessert.

Usually my go-to zucchini recipe is Paula Deen’s zucchini bread.

However, I saw Dorothy at Crazy for Crust make zucchini brownies and knew I had to try my version.

Zucchini Brownie Ingredients

These actual brownies are vegan / dairy-free. The frosting does call for butter but it can be swapped for coconut oil to keep them vegan.

Do I have to peel the zucchini?

Nope.

Many people wonder if you have to peel zucchini before you use it in baked goods and the answer is no, you don’t. Just give the zucchini a wash then grate it, leaving the skin on, with a box grater. That’s it!

They’re all kinds of delicious. They’re very moist and chocolatey. Everyone that has tasted them has said “these have zucchini in them?!”.

I don’t like frosting on brownies so I just drizzled it over the top & they were still plenty sweet.

Ingredients
 

For the brownies

  • 2 cups flour

  • 1 ½ teaspoons baking soda
  • 1 teaspoon salt
  • ½ cup vegetable oil
  • 1 ½ cups sugar
  • 2 teaspoons vanilla extract
  • 2 cups zucchini shredded
  • 2 Tablespoons hot water

For the frosting

  • 1 ½ tablespoons cocoa powder
  • 2 Tablespoons coconut oil (or butter) melted
  • 1 cup powdered sugar

Instructions

To make the brownies

  • Preheat oven to 350 degrees and line a 9×13 inch baking pan with parchment paper. Spray with non-stick spray and set aside.

  1. These look delicious! I’m going to try them this week. How many small zucchinis would you say I need to get 2 cups shredded?
    Thanks!
