This is my mom's recipe. I've never strayed from it because it needs no improvement.
3 zucchini, peeled and shredded
1 C vegetable oil
3 C flour
3 C sugar
3 t cinnamon
1 t soda
1 t baking powder
1 t salt
2 t vanilla
1 C nuts (optional)
Preheat oven to 350 degrees. Grease and flour loaf pans.
Beat eggs and oil. Add dry ingredients and mix well. Add zucchini and beat. Add nuts. Mix well.
Fill loaf pans 1/2 full and bake for one hour. I use mini loaf pans so you only need to bake for 45 minutes if you do the same.
