These rich and fudgy dark chocolate zucchini brownies taste so much like regular chocolate brownies, you’d never guess there’s an entire cup of zucchini in the recipe!

Healthy chocolate zucchini brownies

If you haven’t tried zucchini brownies before, these are a must try.

The zucchini adds unbelievable moisture and softness to the recipe, without all the extra fat and calories. It lets you cut back on the oil, while secretly packing the fudgy chocolate treats with nutrition at the same time.

Brownies that are healthy and don’t taste healthy? It’s the best of both worlds!

Vegan zucchini brownie ingredients

The zucchini brownie recipe can be soy free, dairy free, gluten free, and vegan, with no eggs, no butter, and no flax seeds.

In addition to shredded zucchini, this healthy dessert recipe calls for the following traditional brownie ingredients: flour, sugar, baking soda, salt, oil or almond butter, water, Dutch cocoa powder, and regular unsweetened cocoa powder.

If desired, you can also stir in a handful of mini chocolate chips, chopped chocolate, shredded coconut, or diced walnuts or pecans.

Vitamin packed zucchini summer squash stands in for much of the oil, adding extra moisture and nutrition without all the fat and calories. Or you can use softened almond butter or cashew butter for oil free brownies. I have not tried applesauce here.

Dutch process cocoa powder gives baked dessert recipes a classic brownie flavor, and you will often see this ingredient in boxed brownie mixes. It should be readily available at both health food stores and regular grocery stores.

Refined sugar free sweeteners, such as coconut sugar or date sugar, can be substituted for the granulated sugar. I would guess that xylitol or a granulated monk fruit blend should also work, but I have not tried either of these options.

If you prefer sugar free brownies with almond flour, try the keto brownies listed below. While this particular brownie recipe does not work with coconut flour, I do have a separate recipe for low carb Coconut Flour Brownies.

You can use spelt flour or all purpose white flour, or opt for oat flour to make gluten free zucchini brownies. Some brands of gluten free all purpose flour may also work.

How to make zucchini brownies

Start by gathering the brownie ingredients and shredding the zucchini.

If you are unsure of the best way to shred zucchini, see below.

Preheat your oven to 350 degrees Fahrenheit. Line an eight inch square or round baking pan with parchment paper, or grease the bottom and sides of the pan with oil. Set this pan aside.

Combine all of the dry ingredients in a large mixing bowl, and stir very well. Add the wet ingredients, including the zucchini, and stir to form a batter.

Smooth the brownie batter into the prepared pan. Place on the center rack of the oven.

For ultra fudgy brownies, my favorite baking trick is to remove the underdone brownies after fifteen minutes. Let them cool, then refrigerate overnight so they firm up without being overcooked or cakey. If you are in a rush or do prefer cake like brownies instead of extra fudgy ones, bake the brownies for twenty minutes or until fully cooked.

These brownies, like many baked goods, are much sweeter and richer the next day, with a better brownie texture. So let them sit a day before serving… if you can wait!

The chocolate recipe is great on its own or with Chocolate Cream Cheese Frosting.

Storage tips for zucchini brownies

For optimum freshness, it is best to store leftover brownies in the refrigerator.

Very loosely cover them the first night with a paper towel, then fully cover any remaining leftovers in an airtight container for up to four days.

Or slice and freeze leftovers in a container, with sheet of parchment paper or wax paper in between layers of brownies to prevent them from sticking together.

Once frozen, the healthy zucchini brownies should be good for up to two months.

Warm up or thaw the baked goods before serving.

How to shred zucchini

The recipe calls for one cup of zucchini, which is about one or two zucchini, depending on the size.

I usually buy three zucchini just to be on the safe side, and because leftovers can always be used up in this homemade Coconut Curry Recipe.

The easiest way to shred a zucchini is not with a grater, but with a food processor.

Chop the vegetable into medium pieces, then pulse until finely grated, stopping a few times to scrape down the sides of the machine if needed.

Measure out the one cup of zucchini squash after processing, not before. While some recipes tell you to do so, I didn’t bother to blot out excess moisture here.

The recipe was adapted from my Vegan Brownies.
