Fancy some flourless chocolate zucchini brownies without using traditional wheat flour?
These flourless zucchini brownies use almond butter, grated courgette, raw honey and dark chocolate chips to create a rich, moist treat with plenty of chocolate flavour. The grated zucchini adds moisture to the batter, while almond butter provides the creamy texture that helps hold the brownies together.
They are simple to make in one bowl and are a good option when you want to try something a little different from a conventional brownie recipe.
Zucchini, also known as courgette, might seem like an unusual brownie ingredient, but it has a very practical role.
Grated zucchini contains a lot of water, which helps keep baked goods moist. It also adds a vegetable ingredient without producing a strong vegetable flavour once combined with chocolate, almond butter, and spices.
Why Put Zucchini in Brownies?
The result is a soft, moist brownie rather than a dry, crumbly one.
Remember, adding zucchini does not magically turn a dessert into a health food. These are still brownies, and ingredients such as almond butter, honey and chocolate chips contribute energy and naturally occurring or added sugars.
The appeal is that you can make a satisfying homemade treat from relatively simple ingredients and avoid wheat flour.
Flourless Zucchini Brownie Ingredients
Makes approximately 12 brownies
- 1 cup almond butter
- 1½ cups grated zucchini/courgette
- ⅓ cup raw honey
- 1 large egg
- 1 teaspoon vanilla extract
- 1 teaspoon baking soda
- 1 teaspoon ground cinnamon
- ½ teaspoon ground nutmeg
- 1 cup dark chocolate chips
A note about the chocolate chips
The original recipe describes the chocolate chips as organic and gluten-free. Those terms don’t automatically mean a product meets every definition of a paleo diet.
If you want the finished brownies to fit a strict paleo approach, choose chocolate chips whose ingredients match the particular version of paleo eating you follow. Otherwise, simply use a good-quality dark chocolate chip that you enjoy.
How to Make Flourless Chocolate Zucchini Brownies
- Preheat your oven to 350°F (180°C).
- Lightly grease a 9 x 9-inch (23 x 23 cm) baking pan. For easier removal, you can also line the pan with baking parchment.
- Grate the zucchini using the coarse side of a box grater.
- If the zucchini is particularly watery, gently press out a little excess moisture. Do not squeeze it completely dry because some moisture helps keep the brownies soft.
- Add the almond butter, grated zucchini, honey, egg, vanilla, baking soda, cinnamon and nutmeg to a large mixing bowl.
- Stir thoroughly with a spatula until the ingredients are evenly combined.
- Fold in the dark chocolate chips.
- Spoon the mixture into the prepared baking pan and spread it into an even layer.
- Bake on the middle rack for approximately 35–40 minutes.
- Test the centre with a toothpick. It should come out mostly clean, not covered in wet batter.
- Remove from the oven and let the brownies cool in the pan before cutting into squares.
Don’t Overbake Them
The moisture from the zucchini is part of what makes these brownies appealing, so don’t leave them in the oven longer than necessary.
Ovens vary, so start checking towards the lower end of the suggested cooking time.
The brownies will also firm up as they cool. Cutting them while they are still very hot can make them crumble more easily.
Tips for Better Zucchini Brownies
Grate the zucchini finely
A fine or medium grate helps the zucchini blend into the brownie mixture more easily.
Use creamy almond butter
Smooth, runny almond butter mixes into the batter more easily than a very thick one.
If your almond butter has separated in the jar, stir it thoroughly before measuring.
Choose your chocolate carefully
Dark chocolate chips vary considerably in their ingredients and sweetness.
Darker chocolate can give the brownies a deeper flavour, while semi-sweet chips make them sweeter.
Add a pinch of salt
The original recipe doesn’t include salt, but a small pinch can balance the sweetness and intensify the chocolate flavour.
This is optional.
Are These Brownies Actually Healthy?
It is better to think of these as a more ingredient-conscious brownie rather than a health food.
The recipe contains no wheat flour, and zucchini adds moisture and a vegetable ingredient. Almond butter contributes unsaturated fat and some protein, while honey and chocolate provide sweetness.
However, almond butter is energy-dense, and honey and chocolate chips still contribute sugar and calories. Portion size therefore matters just as it does with any other dessert.
A healthy diet does not require you to avoid every sweet food. What matters is the overall pattern of what you eat.
Are These Brownies Paleo?
They were originally described as a paleo recipe, but there is an important qualification.
“Paleo” isn’t a single, universally standardised diet, and some versions differ over ingredients such as honey and chocolate products.
The basic recipe uses almond butter, zucchini, egg, honey, vanilla, baking soda, and spices instead of wheat flour or refined white flour. To make a version that fits the paleo rules you follow, check the ingredients in your almond butter and chocolate chips and adjust as needed.
That makes paleo-style a more useful description than suggesting that every version of the recipe will meet every strict paleo definition.
Can I Make These Brownies Without Almond Butter?
Almond butter is an important part of the recipe because it provides fat, flavour and structure.
You can experiment with another nut or seed butter, but the texture and flavour may change.
If you have a nut allergy, don’t substitute another ingredient unless you know that it works safely with this recipe.
Can I Make Them Less Sweet?
Yes.
The original recipe uses ⅓ cup of honey plus dark chocolate chips. You can choose darker chocolate chips for a less sweet result.
Reducing the honey substantially may affect the texture as well as the sweetness, so make small adjustments rather than removing it altogether.
How Should I Store the Brownies?
Allow the brownies to cool completely before storing them.
Keep them in an airtight container and use a sheet of baking parchment between layers if you need to stack them.
For longer storage, you can refrigerate them or freeze individual portions.
If freezing, wrap the brownies well and place them in a suitable freezer container or bag. Thaw them in the refrigerator or at room temperature before serving.
When Are These Brownies Best Served?
These brownies make a useful homemade option for:
- An occasional dessert
- A weekend baking project
- A lunchbox treat
- A coffee-time snack
- A homemade alternative to packaged brownies
Enjoy them on their own or serve with fresh berries and a spoonful of plain yoghurt for a simple dessert.
Frequently Asked Questions
Do zucchini brownies taste like zucchini?
Usually, not strongly. When finely grated, zucchini mainly contributes moisture and texture. The almond butter, chocolate, vanilla and spices provide most of the flavour.
Do I need to peel the zucchini?
No. The skin is edible and can simply be grated along with the rest of the zucchini.
Should I squeeze all the water out of the zucchini?
No. Removing a little excess moisture can help if the zucchini is particularly watery, but leaving some moisture helps keep the brownies soft.
Can I use courgette instead of zucchini?
Yes. Zucchini and courgette are two names for the same type of summer squash.
Can I make these brownies gluten-free?
The recipe contains no wheat flour, but always check the labels of packaged ingredients such as chocolate chips and baking soda if you need to avoid gluten strictly. Gluten-free labelling can vary by product and country.
Can I make these brownies dairy-free?
The basic recipe does not contain butter or milk. However, check the ingredients in your chocolate chips because some chocolate products contain milk.
The Bottom Line
These flourless chocolate zucchini brownies are a clever way to make a moist homemade treat using almond butter and grated courgette instead of traditional wheat flour.
They are easy to prepare, require just one mixing bowl, and can be adapted to suit your preferred chocolate and sweetness.
They are still brownies, not a substitute for a balanced diet, but there is nothing wrong with enjoying an occasional homemade treat.
Sometimes a good recipe is simply one that tastes delicious and gives you a little more control over what goes into it.
