As summer comes to an end you and your family may be “zucchini’d out” from the conventional way of cooking zucchini. But today we are switching it up and you will be so glad that you did. 

Not to mention, your little ones won’t have the slightest clue you snuck a vegetable in their new favorite dessert! I love using zucchini when baking, it is the perfect vegetable to sneak into desserts because of its mild taste and its high water ratio keeps brownies, muffins, and cakes moist without worrying about ever being dry!

How to Make Zucchini Brownies that are Healthy AND Vegan

First you will want to preheat your oven and line a 9×13 loaf pan with parchment paper then spray with banking spray

Mix together in a large bowl your oil, sugar, and vanilla until they are fully combined 

Next you will add in your flour, baking soda, cocoa, and salt. Mix it very well. Your batter will be very dry. 

Carefully fold in zucchini by hand, you don’t want to use a mixer. Before the next step let your batter sit for 5 minutes. 

After your batter rests, add chocolate chunks and stir. The batter should look more wet now. (if it still appears dry, let it rest 5 additional minutes then stir)

Use a spatula to spread brownie mix in the pan and bake 25-35 minutes. Your delicious brownies are done when a toothpick can be inserted and removed with no crumbs. You should not see batter on your toothpick. 

Before cutting your brownies add flaky sea salt to the top, let them cool before slicing.

Can you Freeze Brownies?  

If you want to make them in advance or in bulk, these brownies do freeze well! Prepare the brownies as instructed, let them cool completely. 

Cut them into squares and place parchment paper between layers of brownies. Cover in plastic wrap and then wrap in aluminum foil. These frozen brownies will stay good for up to three months in the freezer!

Tips for Using Zucchini in Baking Recipes

  1. Larger zucchini typically have more moisture than smaller ones do. 
  2. Always be gentle with your shredded zucchini.
  3. After you shred it, if you have water in the bottom of the bowl, make sure you drain it well before adding to your other ingredients.
  4. Add in zucchini at the end of the recipe. 
  5. Don’t over mix when you put in your zucchini. Cooked zucchini brownies with salt topping sitting stacked on a white, spiral-textured plate on white background.

    Such a great recipe!
    I made them for dessert last night and they turned out amazing. We are not vegan so I used butter instead of coconutoil and added two eggs. And as we don‘t like it too sweet, 1/2 cup coconutsugar was enough and perfect for us.
    Will definitely make it again!
