Heat the oven to 325 and grease 2 8 1/2-by-4 1/2-inch loaf pans or spray them with baking spray.

Combine the flour, baking powder, soda, salt, and spices in a bowl; stir or whisk to blend thoroughly. Set aside.

Combine the eggs, vegetable oil, sugar, and vanilla in a mixing bowl. Whisk until smooth and well blended.

Add the dry ingredients and stir to blend to make a thick batter.

Fold in the zucchini and nuts (1f using).

Spoon the batter into the prepared loaf pans and bake for 55 to 65 minutes or until a toothpick inserted into the center comes out clean.

Cool the loaves in the pans on a rack for 10 minutes, then turn them out onto the rack to cool completely.

Slice and enjoy!
