Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper or lightly grease it with oil. This prevents the brownies from sticking and makes them easier to remove once baked.

Wash the zucchini and grate it using a box grater. If the zucchini seems very watery, lightly pat it with a paper towel, but do not squeeze it completely dry since the moisture helps keep the brownies soft.

In a large mixing bowl, whisk together the eggs, maple syrup (or honey), melted coconut oil, and vanilla extract. Stir until the mixture becomes smooth and well combined.

Fold the grated zucchini into the wet mixture. Make sure it’s evenly distributed so every bite of brownie stays moist.

In another bowl, mix the whole wheat flour, cocoa powder, baking soda, and salt. Stir well so the cocoa powder and baking soda are evenly incorporated.

Gradually add the dry ingredients into the wet ingredients. Stir gently until just combined. Avoid overmixing. If you’re using chocolate chips, fold them into the batter at this stage.

Pour the batter into the prepared baking pan and spread it evenly. Bake for 20–25 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.

Let the brownies cool in the pan for at least 10–15 minutes before slicing. This helps them set and makes them easier to cut.
