Are Zucchini Brownies Keto?

Zucchini is a very low-carb keto vegetable, but unfortunately, a classic zucchini brownie recipe is not keto-friendly.

In fact, the authentic zucchini brownie recipe contains high carbs ingredients, including wheat flour, sugar, and sometimes melted chocolate.

Therefore, to enjoy a moist, fudgy chocolate brownie recipe with zucchini and no sugar, you must follow my recipe below.

How To Make Keto Zucchini Brownies

Luckily, it’s super easy to make a keto zucchini brownie recipe.

So, if you are overloaded with zucchini this summer, this keto brownie recipe comes to the rescue!

Ingredients

All you need to make this brownie recipe are:

• Shredded zucchinis – Make sure you trim ends and keep the skin on to preserve the important nutrient and fiber of these keto-friendly vegetables. Below I explain how to perfectly prepare zucchinis for keto brownies. Keep reading for tips and tricks.
• Almond flour – I used ultra-fine almond flour for the best texture. Almond meal is coarse and slightly gritty, and I don’t recommend this option for my keto baking recipe. However, if it’s all you have in the pantry, the recipe works with it. But, the texture of the keto zucchini brownies won’t be as smooth. Read how to choose the best keto flours.
• Unsweetened cocoa powder
• Sugar-free crystal sweeteners like erythritol or a combo of erythritol and monk fruit. You can use my keto sweetener converter to swap for any other sweetener brands you have at home.
• Large eggs – at room temperature. Note that this recipe won’t work without the eggs or using egg replacer like flax eggs. You must use eggs, or the brownie batter won’t hold together. Follow my egg-free keto brownie recipe if you can’t eat eggs.
• Baking powder or use half the amount of baking soda.
• Sea salt
• Unsweetened almond milk – at room temperature.
• Melted butter or melted coconut oil for a dairy-free paleo option.
• Vanilla extract
• Dark sugar-free chocolate chips – this is optional but adding 1/4 cup to 1/2 cup of sugar-free chocolate chips adds the best extra chocolate flavor in this low-carb zucchini brownie recipe.

Preparing The Pan

First, preheat the oven to 325°F (160°C). Line an 8-inch square baking pan with parchment paper and lightly oil the paper with cooking spray or butter.

Set it aside.

Preparing The Zucchinis

The best way to make a moist low-carb zucchini brownie is to:

• Shred the zucchini finely using the smaller grating attachment of your hand grater.
• Drain out the zucchini water – with 95% water in zucchinis, you must remove their juice before adding the shredded zucchinis to the batter, or your brownie would end up very soft and fragile.
• Measure the shredded and drained zucchinis – always drain the shredded zucchinis before measuring the amount required by the recipe for precision.

Combining Ingredients

First, in a large mixing bowl, stir almond flour, cocoa powder, baking powder, and salt. Set aside.

In another mixing bowl, beat eggs, almond milk, melted butter, and vanilla extract. Finally, stir in the shredded, drained zucchinis.

Finally, stir the liquid ingredients into the dry ingredients until it forms a thick, smooth keto brownie batter.

If you like, and I actually highly recommend it for sweetness, stir in some sugar-free chocolate chips in the batter.

Baking

Spread the batter into an 8-inch square pan. Bake in the center rack of your oven until the top is just set and starts to dry out.

Don’t overbake the keto zucchini brownies, or they would lose all their moisture.

You can insert a toothpick in the center of the brownie to check their baking progress. If the pick comes out with a little crumb on it, remove the pan from the oven.

Cool the brownie down in the pan for 5 minutes, then use the hanging pieces of parchment paper to release the keto zucchini brownies onto a cooling rack.

Cool Completely

Cool the keto brownies with zucchini for about 30 minutes before slicing.

If you want to add a chocolate ganache on top of your brownies, wait until they reach room temperature.

Serving Ideas

These keto zucchini brownies are delicious on their own but even better served with a dollop of:

• Sugar-free vanilla ice cream
• Whipped cream – you can use whipped canned coconut cream for a dairy-free option.
• Fresh berries like raspberries or strawberries.
• Peanut butter or almond butter – drizzle some drippy nut butter on top of your slice, and you just made the best keto dessert ever!

Nutrition

The nutrition panel below includes the sugar-free chocolate chips glaze.

I highly recommend adding both options for the most delicious keto chocolate dessert.

Storage

These zucchini brownies can be stored for up to 4 days in an airtight container in the fridge.

The texture of these keto brownies becomes fudgier in the fridge, and I actually recommend waiting for a few days to enjoy an even more intense chocolate fudgy texture.

Of course, this keto brownie recipe can be frozen as well, and it’s a great idea for portion control.

Wrap one serving of keto zucchini brownie on a ziplock bag and freeze.

Thaw your keto zucchini brownies at room temperature the day before.

Allergy Swaps

Of course, if you want to make changes to this recipe, I have suggestions for you to try.

• Dairy-free – swap melted butter for melted coconut oil or light olive oil.
• Nut-free – replace almond flour with the same amount of fine sesame flour or sunflower seed flour. These flour options are keto-friendly and gluten-free but add a light, bitter flavor to keto baked goods.
• Egg-free – unfortunately, I had no success making these brownies with egg replacement like flax eggs. The texture is too fragile, and the brownies fall apart. Use my keto egg-free brownie recipe if you have an allergy to eggs.
• Zucchinis – you can replace zucchinis with summer yellow squash.
