Recipe Tips

  • MEASURE EXACTLY: Do not add more or less than 2 cups of minced zucchini, or they will not turn out well.
  • ALLOW THE BATTER TO REST: The mixture for these brownies will first appear to be very dry. But once you stir in the zucchini, let it rest for 5 minutes. Then allow the zucchini “to work its magic,” giving enough moisture to stir the mixture.
  • USE A SPATULA TO SPREAD: It is best to use the back of a wooden spoon or spatula to help spread the batter evenly in the baking pan.
  • DO NOT OVER BAKE: When you smell the “chocolate aroma” from the oven, that is an indication that the brownies are almost ready. Check on them. You can lightly press down in the center to see if it springs back – then it’s ready!
  • COOL BEFORE CUTTING: Allow the sheet pan to cool completely before cutting it into smaller squares- like brownies. If the brownies are too warm, they will fall apart, and you will have a mess.

What Do We Need?

For this recipe, you will need one mixing bowl, a large wooden spoon to stir the mixture, and a spatula to spread the mixture in your baking pan. Also, we used our favorite Farberware Non-Stick Baking Pan to bake them.

How To Buy & Choose the Zucchini?

When shopping for fresh zucchini at the market, keep these tips in mind:

  1. Size: We prefer medium-sized and even small-sized zucchini for this recipe. These are often more flavorful and tender compared to the larger ones.
  2. The Color: Look for bright or dark green zucchini and skins without blemishes.
  3. Its Weight: The zucchini should feel light in weight, rather than heavy. If they feel heavy, usually that means they will contain more seeds, and you don’t want those.
  4. And, Firmness: When fresh, they are nice and firm to the touch. Never buy them if they are soft and flimsy.

Helpful Tip! Peak season for zucchini is typically during early to late summer. But you will find them all year long. And, you’ll want to use them within a few days after purchase.

How To Make the Best Chocolate Zucchini Brownies?

Before you start. First, gather all the ingredients needed for this recipe. Then you can easily follow our 4-Easy-Steps to making this brownie recipe. (*Our full recipe card and VIDEO are also located below!) But first, let’s run through the steps so you can see what’s involved before you start.

1. First: Preheat your oven to 350 degrees F (180C). Spray your 13 x 9 (or 12 x 9) baking pan with cooking spray, and dust with flour on all 4 sides. Or use parchment paper for easy clean-up.

2. Next: Mince or shred the zucchini and measure ONLY 2 cups packed! Place the minced zucchini into a small bowl, and set it aside.

3. Measure the first 8 ingredients, and stir them to combine. Stir in the flour until it is completely combined with the cocoa. Then add the zucchini, and stir until well combined (the mixture will be very thick and dry). Now, set the bowl aside, and WAIT at least 5 minutes! …Allow the zucchini to do “its magic! (The zucchini will give enough moisture to stir the batter).

4. After 5 Minutes: Add the “mini” chocolate chips and stir the mixture again until well combined. The mixture will be soft and moist at this point.

5. Transfer the brownie batter to your prepared baking pan. Use a spatula to transfer to your prepared baking pan and spread it evenly on the bottom of the pan. Take your time smoothing and spreading it. The batter will feel thick, so take your time.

QUICK NOTE: The batter will seem to be very thick. And the appearance will be speckled with bits of green and yellow zucchini. Plus, the batter will give a very “thin layer” when it’s transferred to the pan before it bakes,…and that’s OK. (see my notes below)

FAQ’s

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

2. Should we scrape the skins off the zucchini? If the zucchini is not organic, it may be too gritty and sandy from the farmer’s market.ย  Therefore, I prefer to lightly scrape the skins off the zucchini, using a knife (see in the video). Then give them a good rinse.

3. What does “packed” mean? When you measure the minced zucchini, use the back of your spoon to press down firmly into the measuring cup, and level it at the top. This is how to measure each cup correctly.

4. Should we “Shred” or “Mince” zucchini? Most recipes require shredding zucchini, using a traditional grater. But it takes more effort, and it is very time-consuming.ย  So why not go the easier route and use a mini chopper to mince in seconds?

*PRO TIP! I prefer to use my mini chopper and pulse zucchini into tiny, minced pieces. It works much faster, and easier!

5. 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 “extra moisture” for this recipe.

6. Does the size of the zucchini matter? Yes, the smaller size of zucchini contains more moisture than the larger ones, so they are better when making these brownies.

7. How To Store and Freeze? Best to store these brownies in an air-tight container and in the refrigerator to keep them chilled. They will stay fresh longer and for more than 1 week. They freeze well, too, and for up to 2 months.

Substitutions:

1. Can we make them gluten-free? Keep in mind, not all GF flours are the same.ย  And, while some may work, others will fail. We have tried this recipe using oat flour and again with coconut flour, but neither works.ย  I have not tried this recipe with an all-purpose gluten-free flour … but if you do and it is successful?ย Please tell us, it will benefit bakers who are looking for GF options.

2. 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.

3. 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.

Ingredients

  • 1/2 cup (109 grams) olive oil
  • 1 cup (180 grams) coconut sugar (or brown sugar)
  • 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
  • 2 cups (240 grams) unbleached, all-purpose flour
  • 2 cups (350 grams) packed zucchini - minced (about 2 or 3 small zucchini)
  • 1/2 cup (80 grams) mini semi-sweet chocolate chips
  • powdered sugar, for dusting

Instructions

  1. Preheat OVEN to Bake at 350 degrees F (180 C). Rearrange your oven racks so that one is in the center of the oven.
  2. Spray with cooking spray on the bottom and sides of a 9 x 13-inch (or 12 x 9) baking pan, and dust with flour evenly. Set the pan aside.
  3. Rinse, cut off ends, 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, use 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.
  5. Add in the flour gradually, 1 cup at a time. Continue to blending, until the mixture darkens in color as it absorbs the flour and blends completely, Use the wooden spoon to help break up any large balls.
  6. Next, add the zucchini and blend. The mixture will continue to seem very dry and very lumpy. Blend until well incorporated. Set it aside for a few minutes, at least 5 minutes, and let the zucchini do its magic!
  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 incorporated. The mixture will be very moist and thick.
  9. Pour the batter into the prepared pan. Use the back of a spatula or a wooden spoon to help you smooth the batter evenly into the pan.
  10. BAKE for 22 to 26 minutes, until when lightly touched in the center brownies spring back or check with a toothpick inserted and it comes out clean. Remove from oven and allow to cool completely in the pan, and on your counter or a wire rack before cutting.
  11. Yields: 18 servings
