Preheat the oven to 180C/350F. Grease a loaf pan and set aside.
In a mixing bowl, mix your almond flour, coconut flour, baking powder, and salt, and set aside.
In a separate bowl, whisk together the eggs, brown sugar, oil, vanilla extract, and shredded zucchini. Slowly add your dry ingredients into the wet ingredients and mix until combined.
Fold through the chocolate chips.
Transfer the batter into the greased loaf pan. Bake for 45-50 minutes, or until a skewer comes out mostly clean.
Remove from the oven and let the bread cool completely before slicing up.
