Preheat oven to 350 degrees Fahrenheit
In a small bowl mix the dry ingredients (cake flour, baking soda, spices, and toasted and cooled walnuts). Whisk and set aside.
In a glass or ceramic mixing bowl beat the eggs, sugar, maple syrup, and oil for at least 2-3 minutes or until smooth. When using eggs, I always take the time to remove the chalaza. This prevents my bake goods using eggs from tasting “eggy”. But if you don’t mind that taste, you can keep the chalazas on the yokes.
Add the grated zucchini, mix in, then add dry ingredients. Mix well. Add raisins if you choose to use this ingredient. Scrape the batter into a prepared loaf pan or into greased muffin pan, each about 3/4 full.
Bake in loaf pan for about 40-45 minutes, turning halfway through. Batter in muffin pans, could take only about 20-25 minutes. Again, if you choose to use a muffin pan, turn halfway through the baking cycle. Setting a timer helps me to remember. At end of the baking time, test with a toothpick to confirm doneness.
