What Goes Into Zucchini Brownies

These brownies use simple, dependable ingredients that come together in one bowl. The zucchini keeps everything tender while the cocoa and peanut flour build that classic brownie texture.

• Finely Shredded Zucchini: Using the smallest side of your grater gives you a puree-like texture that melts into the batter, creating fudginess without extra oil or flour.
• Peanut Flour: Adds structure with a naturally nutty depth, working as a lighter stand-in for traditional flour.
• Butter: Gives the brownies a soft crumb and richer flavor while helping the cocoa bloom.
• Unsweetened Cocoa Powder: Provides deep chocolate flavor and balances the natural moisture from the zucchini.

Note: Please see recipe card at the bottom for a full list of ingredients with measurements.

On the stove

1. Preheat The Oven: Preheat your oven to 176°C or 350°F. Line an 8 inch square baking pan with parchment paper or lightly grease it with oil spray and set aside.

1. Mix Wet Ingredients: In a bowl, whisk the shredded zucchini, butter, oil, egg, sweetener or sugar, and vanilla until the mixture is smooth and well combined.

1. Add The Dry Ingredients: Add the peanut flour, cocoa powder, baking powder, and salt into the bowl. Fold everything together slowly until the batter is just combined.

1. Adjust The Batter: Check the consistency of the batter. It should be thick but not dry, so if it seems too stiff, gently mix in 1 to 2 tablespoons of water until it loosens slightly.

1. Fold In The Chocolate: Add half of the chopped chocolate pieces to the bowl and fold them through the batter so they are evenly distributed.

1. Fill The Pan: Pour the batter into your prepared pan and spread it out in an even layer. Sprinkle the remaining chocolate pieces over the top.

1. Bake The Brownies: Bake for about 30 minutes or until the brownies spring back when gently touched in the center. The middle will still look moist but will firm up as it cools.

1. Cool And Slice: Allow brownies to cool completely, then cut into squares. Chill them to help them semi set and store in an airtight container at room temperature or in the fridge.

These Zucchini Brownies are rich enough to shine on their own, but they pair beautifully with something savory to round out the moment. We love serving them after The Ultimate Pull Apart Cheesy Garlic Bread because it adds a cheesy, satisfying hit before you settle into your brownies.

Kitchen tip

• Squeeze the zucchini lightly if it feels too wet. You still want moisture, but removing the excess keeps the brownies from turning mushy.
• Do not overmix the batter. A gentle fold keeps the brownies tender and helps them stay fudgy in the center.
• Let the brownies cool completely before slicing. They firm up as they rest, so patience gives you cleaner squares and a better texture.
• Chill the brownies if you want them extra dense. A short rest in the fridge creates that classic fudgy bite.
• Taste your cocoa before adding it. Some cocoa powders are more intense, so use the amount that matches your preferred level of richness.

Recipe FAQ's

Yes. Any granulated sweetener or regular sugar works well in these Zucchini Brownies. Just keep the measurements the same so the texture stays consistent.

Only if it is wet. Most finely grated zucchini works perfectly as is and gives your healthy zucchini brownies their soft, fudgy bite.

You can reduce the oil slightly, but do not remove it entirely. The oil helps balance the moisture from the zucchini and creates the fudgy center.

What you need

• 1 cup finely shredded zucchini – use the smallest blade on a cheese grater. It should look like a puree
• 6 tablespoons butter melted
• 2 tablespoons coconut oil measured in melted state, or sub with any vegetable oil you have
• 1 large egg
• 1/2 cup natural granulated sweetener or granulated sugar of choice – coconut; white sugar *See Notes
• 1 tablespoon pure vanilla extract
• 3/4 cup peanut flour
• 1/3 cup unsweetened cocoa powder or 1/4 cup if you don't like them too rich
• 1 teaspoon baking powder
• 1/4 teaspoon sea salt
• 4 squares Lindt 90% chocolate or chocolate of choice cut into pieces/chunks

Method

1. Preheat oven to 176°C | 350°F. Line a 8×8″ baking pan with baking?parchment paper, or lightly grease with oil spray. Set aside.
2. In a medium bowl, whisk together the zucchini, butter, oil, egg, sweetener (or sugar), and vanilla until well combined. Add the peanut flour, cocoa powder, baking powder and salt; folding through slowly until just combined. The batter will be thick but shouldn't be dry. (It depends on how much liquid your zucchini has! If too dry, add 1-2 tablespoons of water). Fold in half of the chocolate chunks; pour batter into prepared pan; sprinkle remaining chocolate chunks over the top.
3. Bake for 30 minutes or until the brownies spring back when gently touched. (If testing with a toothpick, they will be moist in the centre BUT they do set and harden when removed from the oven.)
4. Allow to cool completely (about half an hour); cut into squares and chill to semi-set.
5. If storing at room temperature they're best eaten within 2 days. If refrigerating, they last 3-4 days.
