How to Make It
Preheat oven to 350 and place a rack in the middle of the oven. Spray a loaf pan with cooking spray, then place a strip of parchment paper across the middle to give a sling with which to remove the baked loaf. Give the parchment a little cooking spray for good measure.
In a large bowl with a wooden spoon, mix the oil, sugar, eggs, and vanilla until well blended. Add the two flours, baking soda, cinnamon, salt, and baking powder. Mix well. Stir in the shredded zucchini, and then the nuts and chocolate chips, and mix till well combined.
Using a rubber spatula, pour the batter into prepared loaf pan and smooth the top. Bake until a toothpick stuck in the middle comes out clean, about 70-80 minutes. Let cool in the pan on a rack for at least 15 minutes, then gently remove from the loaf pan using the parchment as a sling. Let continue to cool on rack until fully cooled before slicing.
