How to Make these Chocolate Zucchini Brownies?

1. First: you will need one bowl, and a large wooden spoon to stir the mixture.

2. Next, you will need to stir the first half of the ingredients. Then stir in the flour and zucchini. WAIT at least 5 minutes. Set aside the bowl, for at least 5 minutes, to allow the zucchini do “its magic! “

3. Final Step: Add the “mini” chocolate chips and stir the mixture until it is well combined. Transfer to your prepared baking pan and bake.

Baking Notes and Tips…

  • The mixture for these brownies will first appear to be very dry.  But once you stir in the zucchini and let it rest for a few minutes, the zucchini “will work its magic” giving enough moisture for you to stir the mixture.
  • Keep in mind, that the mixture will be very thick, so use the back of a spoon to help spread the batter in the baking pan.
  • Do not overbake.  The brownies are baked for about 22 to 25 minutes.  They are done when you lightly press down in the middle and it springs back.
  • Allow the brownies to cool before cutting into them, or they will fall apart.

Questions & Answers…

1. Can we taste the zucchini? Not at all.  In fact, the additional chocolate chips added to them make these brownies so incredibly decadent –  they are unsurpassed!

2. Should we scrape the skins off of zucchini? If the zucchini are not organic, they may come too gritty and sandy from the farmer’s market.  Therefore, I prefer to lightly scrape the skins off the zucchini, using a knife.  Then give them a good rinse.

But it’s not necessary.

3. Shred or mince zucchini? Most recipes require shredding zucchini, using a traditional grater. Besides, using a traditional grater to shred zucchini is fine, but it takes more effort and is very time-consuming.  So why not go the easier route?

  • Instead, I prefer to use my mini chopper and pulse my zucchini into tiny, minced pieces.  It’s so much faster, quicker, and easier.

4. Do we need to squeeze excess water from the zucchini? I never do.  No need to squeeze anything, or drain the zucchini.  We need the moisture from the zucchini to make these brownies amazingly moist and delicious.

5. Does the size of the zucchini matter? Yes, the smaller size of zucchini contains more moisture than the large size and is better to use when making these brownies.


6. Can we make them gluten-free? Keep in mind, not all GF flours are the same.  And, while some may work, others will fail.

  • I have tried this recipe using oat flour, and again with coconut flour, to which both did not work.  I have not tried this recipe with an all-purpose gluten-free flour … but if you do and it was successful? 
  • Please tell us, it will benefit bakers who are looking for GF options.

7. Can we use a different sugar if we don’t have coconut sugar? Yes, replace the coconut sugar with an equal amount of dark or light brown sugar.

8. What can we substitute for 1/2 cup of granulated sugar? You can use honey, applesauce, or maple syrup. Keep in mind, that the texture may slightly turn out differently.

  • 1/2 cup granulated sugar (50 grams)
  • 2 tsp. vanilla extract
  • 1/2 cup (50 grams) unsweetened cocoa powder
  • 1 + 1/2 tsp. baking soda
  • 1 tsp. salt
  • 1/2 tsp. ground cinnamon

  3. Rinse and lightly scrape the skins off of the zucchini. Chop into chunks and place some into your mini chopper or food processor. Finely chop the zucchini into minced pieces. Measure 2 cups packed and place into a small bowl. Set it aside.
  4. In a large mixing bowl, using a large wooden spoon to blend oil, sugar, vanilla extract, cocoa powder, baking soda, salt, and cinnamon. The mixture will be very wet and lumpy.

  7. After 5 minutes, stir to blend again and the mixture should be moist and very thick. Scrape the bottom and sides of the bowl with a spatula, then blend again.
  8. Finally, fold in the mini chocolate chips and blend again until well corporate. The mixture will be very thick.
