Why You'll Love This Recipe

Our garden is always bursting with zucchini in the summertime, so I love coming up with creative ways to use it! Chocolate Zucchini Bars are one of my favorite zucchini recipes because they taste just like fudgy brownies.

Zucchini is one of my favorite vegetables to use in baked goods because it has a very neutral flavor. This allows you to easily sneak it into desserts.

Your family will never guess that these super moist zucchini bars are actually made with healthy ingredients like coconut flour, coconut oil, and cacao powder.

Double Chocolate Zucchini Bars Are:

• Incredibly Moist
• Extremely Chocolatey
• Made with Simple Ingredients
• Gluten-Free
• Dairy-Free
• Grain-Free
• Refined Sugar Free

🍴Ingredient Notes

• Shredded Zucchini - Zucchini holds a lot of water so make sure you squeeze it out with a dish towel or cheese cloth. If you don't, it will alter the texture of the bars.
• Eggs - I would not recommend swapping for an egg replacement.
• Coconut Sugar - Any granulated sugar will work. For a sugar-free sweetener, try using Lakanto Golden Monkfruit.
• Coconut Oil - Measure the coconut oil first and then melt in the microwave until liquid.
• Vanilla Extract - To balance out the rich chocolate flavor, I like adding in a little vanilla extract to my chocolate recipes.
• Cacao Powder - To give these bars a deep chocolate flavor, you'll need cacao powder or cocoa powder.
• Coconut Flour - Do not swap for any other flour. For more information, check out my blog post on why you can't use coconut flour as a 1-1 swap with other gluten-free flours.
• Baking Soda - You'll need a small amount of baking soda to help these zucchini bars rise in the oven.
• Salt - I use a pinch of salt in this recipe, but I also like adding flaky sea salt on top of my chocolate desserts!
• Dark Chocolate Chips - Any dark chocolate will work with this recipe! My favorite dairy-free and vegan brands are Pascha and Hu Kitchen.

🍴Step by Step Instructions

Step 1: Mix Wet Ingredients

Start by adding all wet ingredients into a large bowl. Whisk together or use a hand mixer.

Step 2: Stir In Dry Ingredients

Then add in all dry ingredients and chocolate chips. Stir together until all flour has been absorbed.

Step 3: Fold Together

Then pour the dry mixture into the wet mixture and stir together until all flour has been absorbed. Fold in the chocolate chips.

Step 4: Bake Zucchini Bars

Pour the chocolate zucchini bar batter into a greased 8x8 baking dish. Sprinkle on some extra chocolate chips and bake at 350 degrees for about 25-30 minutes.

Step 5: Cool & Serve

Remove them from the oven and let the bars cool on a wire rack for at least 30 minutes before cutting and serving.

Expert Tips

• Use a box grater to shred the zucchini. If you don't have one, you can try adding small chunks of zucchini into a food processor. Pulse until you reach your desired consistency.
• After shredding the zucchini, make sure you use a dish towel or cheese cloth to squeeze out the excess water.
• Do not cut into the bars immediately after baking or they will fall apart. Allow them to cool for at least 30-60 minutes.
• When measuring the flour and grated zucchini, do not pack them into the measuring cup. This will alter the final result.
• Usually, I use parchment paper to prevent sticking, but these brownies are very moist, so I suggest greasing the baking dish with a non-stick avocado oil spray or spread coconut oil with a paper towel.
