Healthy brownie recipe with zucchini

Summer is hands down my favorite season for fruit and vegetables. From juicy blueberries to colorful tomatoes, there are always a tons of healthy greens in our fridge. We like varying our foods, but if there is one vegetable that can never miss at home during summer: zucchini.

Air fryer zucchini fries, zucchini pizza crust and zucchini noodles always find a spot on our weekly menu rotation. Even for desserts, because let's face it, there's always room for dessert. In the past we've already made chocolate zucchini bread and other zucchini bread recipes, but now there's a new sheriff in town: Chocolate Brownies with Zucchini!

Believe me when I say that these may be the best healthy brownies ever. They're rich and fudgy like real brownies, but made healthy with no refined flour, no refined sugar and plenty of fresh greens. The secret ingredient is zucchini. Stirring shredded zucchini into the batter adds moisture and fudginess without the need for whopping amounts of fats. But make sure you don't squeeze out all the water, or the result won't be the same.

Ingredients and substitutes

The art of making the best zucchini brownies that are perfectly fudgy but not too moist involves choosing the right ingredients. Especially the zucchini, the main actor on stage. Here are some more details, alongside tips and substitutions.

• Zucchini. You'll need one and a half cup of shredded zucchini, which correspond to about 2 medium fresh zucchini. There's no need to peel them, but you will want to remove any seed if there are any. They taste bitter and shouldn't go in the brownie mix.
• Egg. Use a large whole egg, it helps bind the batter and improves the flavors. The only close replacement is flaxseed egg, if you want to make vegan zucchini brownies. Applesauce or mashed banana will not work, instead.
• Maple syrup. I like sweetening these easy zucchini brownies with pure maple syrup, it is sweet but not overpowering. As a replacement you can use raw honey, agave syrup, date syrup or coconut syrup. Granulated sweeteners like sugar are not suitable.
• Coconut oil. This makes our brownies extra fudgy and rich without the need for butter or dairy. I recommend coconut oil because it solidifies once the brownies cool, but you can swap it out for a neutral oil like avocado oil.
• Almond butter. This healthy brownie recipe with zucchini uses a combination of coconut oil and almond butter. The nut butter adds moisture and richness while providing health benefits. Great replacements are cashew butter, tahini, sunflower seed butter or more coconut oil.
• Whole wheat flour. I find that baking zucchini brownies with whole wheat flour produces the best result, ensuring they rise well. As an alternative you can use all purpose flour, spelt flour, oat flour or almond flour.
• Cocoa powder. Use unprocessed cocoa powder without added sugar for a healthy dessert. Dutch cocoa will also work.
• Chocolate chips. Dark chocolate chips without added sugar are my favorite, they melt nicely and create a chocolatey brownie experience. Replace with the chocolate chips you like the most.

How to make zucchini brownies easy?

1. Step 1 - Prepare the zucchini. Grate the zucchini. Once grated, gently squeeze the vegetable without removing all the water. Set aside for later while you mix the wet ingredients.

2. Step 2- Make the brownie batter. In a large mixing bowl, whisk egg with maple syrup, melted coconut oil, almond butter, vanilla extract and a pinch of salt. Once evenly combined, stir the grated zucchini into the egg mixture. Add wholewheat flour and baking soda into the wet mixture, then stir to combine. Finally, fold through the chocolate chips.
3. Step 3 - Bake brownies with zucchini. Transfer the brownie batter to your prepared baking pan and top with more chocolate chips, if you desire. Bake in hot oven for 25 to 30 minutes, or until the center has slightly set. Do not over bake brownies, they tend to become firmer as they cool.
4. Step 4 - Let the dessert cool. Let healthy zucchini brownies cool completely, then remove from the baking pan and slice into 16 pieces.

How to store zucchini brownies?

To store homemade zucchini brownies, let them cool completely first. Once they have cooled, slice the dessert and transfer into an airtight container. You can keep them at room temperature for up to 3 days.

For longer storage, refrigerate in an airtight container for up to a week. To freeze, place healthy zucchini brownies in zipper bags or in a freezer-safe container, and freeze them for up to 3 months. When ready to enjoy, thaw them ahead and quickly reheat in hot oven or in the microwave until warm and fudgy.

Success tips

• Do not squeeze out all water from the zucchini, or they may get quite hard. Leaving some moisture ensures that zucchini brownies become rich and fudgy like the original, but without excessive amounts of oil or butter.
• Measure the ingredients with precision, or the brownies will not come out as expected. Especially when it comes to the grated zucchini, do not pack the cups tightly.
• Do not over bake the brownies, as they tend to set further while they cool. You know they are ready when the top is still soft and slightly jiggly but they are not raw inside. Mine took about 25 minutes in the oven, but depending on the power of your oven they may require up to 30 minutes.
• Let the dessert cool completely once it is ready, or your courgette brownies will be too soft. Actually, I find that they taste better on day two. The chocolate flavor deepens and the textures improve.
