Preheat the oven to 350F. Grease 3 mini loaf pans with cooking spray or coconut oil. In a medium bowl, combine the dry ingredients. Whisk to evenly distribute. Add the brown sugar, white sugar, eggs, coconut oil, almond milk, lemon juice, and vanilla. Using a hand mixer, mix on low to evenly combine. Add the zucchini and mix for 30 seconds or so on low to combine. Add the walnuts or chocolate chips and stir to combine. Pour the batter into the prepared loaf pans. Bake for 25-30 minutes, until set in the middle. Let sit in the pan for 10 minutes to cool, then turn out onto a wire rack to continue cooling. Store leftovers wrapped tightly in plastic wrap at room temperature. Enjoy!
