Line a 8.5x4.5 loaf pan with parchment. Preheat your oven to 350°F.
In a medium bowl, add flour, cinnamon, salt, baking powder and baking soda and whisk together. Set aside.
In a large bowl, combine brown sugar, granulated sugar oil and mix.
Add your eggs and mix until eggs are homogenous with the sugar mixture.
Add your grated zucchini and vanilla and stir together.
Add in your dry ingredients and stir until mostly combined, then add walnuts and chocolate chips and mix until evenly distributed and no dry bits of flour are left.
Pour your batter into the prepared pan.
Place on the center rack of your oven and bake for 60-70 minutes. A toothpick will come out cleanly and an internal thermometer probe will read 180°F.
Remove from oven and let cool in pan for about 30-45 minutes. Remove loaf from pan and onto a wire rack to finish cooling. Let bread completely cool before slicing. Store in an airtight container, enjoy!
