  • 1 cups shredded zucchini *-see notes below (about 1 medium-sized zucchini)
  • 1 large egg (may omit for vegan brownies)
  • 1 cup creamy nut butter (I have used cashew and almond)
  • 1/4 cup maple syrup
  • 1/4 cup cacao powder (may substitute cocoa powder)
  • 1 teaspoon baking soda
  • 1 teaspoon vanilla extract
  • 1/4 cup chocolate chips (additional amount needed if making a frosting)
  • 2 tablespoon chopped raw walnuts (optional)


  1. Preheat the oven to 350 degrees F.

  2. Prepare an 8 x 8 brownie pan by spraying with coconut oil and lining with parchment paper.

  3. In a medium-sized mixing bowl, add all ingredients except chocolate chips and walnuts and mix until combined thoroughly.

  4. Fold in chocolate chips and incorporate them.

  5. Pour mixture into your prepared baking dish and sprinkle top with chopped walnuts if using.
  6. Bake for about 30 minutes or until a toothpick comes out clean. Let cool completely and then cut into squares (about 9).

Recipe Notes

Tips and Techniques:

  • Grate the zucchini using a hand cheese grater (easiest and fastest) using the large holes.
  • No need to squeeze liquid from grated zucchini.
  • Use organic zucchini if possible.
  • The zucchini brownies with an egg are a little more cake-like and the vegan zucchini brownies without an egg are fudgier.

Do you grate zucchini with skin on or off?

  • This is your choice, but I leave the skin on and the brownies come out perfectly.

Can you freeze zucchini brownies?

  • Probably yes, but I have not tried this yet (they disappear too fast).

What do healthy zucchini brownies taste like?

  • They taste great!  I cannot detect any zucchini and they are fudgy and delicious!
