Preheat your oven to 350°F (175°C) and grease a loaf pan to prevent sticking.
Using a grater, shred the zucchini, then squeeze out the excess water with your hands until it feels cool and slightly slippery to the touch.
In a large mixing bowl, combine the flour, brown sugar, and cinnamon, whisking together to evenly distribute the dry ingredients.
In a separate bowl, whisk the eggs until well beaten and then stir in the oil.
Pour the wet mixture into the dry ingredients and fold together gently with a spatula, just until combined.
Fold in the shredded zucchini, ensuring it’s evenly distributed throughout the batter.
Pour the batter into the prepared loaf pan, smoothing the top with your spatula for an even surface.
Bake in the preheated oven for 50 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.
Remove from the oven and let the loaf cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
Slice the bread once fully cooled, revealing a moist, tender crumb with flecks of zucchini inside.
Enjoy slices plain or with a spread of butter or cream cheese for extra flavor.
