Preheat oven to 350 degrees Fahrenheit. Grease and flour well 2 bread loaf pans. I like to use 4 mini loaf pans for gifts. Sift together the flour(s), wheat germ if using, cinnamon, salt, baking soda and baking powder. In a separate bowl combine the eggs, brown sugar, white sugar, and oil. Add the dry ingredients slowly to the egg mixture. When thoroughly mixed, add the sour cream and vanilla. Finally, mix in the shredded zucchini, nuts and/or raisins. Pour the mixture into the two loaf pans (or mini pans). Bake at 350 degrees Fahrenheit for about 1 hour and 20 minutes. If baking mini loaves, adjust time to about 50 to 60 minutes. Use a toothpick placed in the center of the loaf to see if the loaves are done. The toothpick should be clean or just have a few crumbs on it. Enjoy!
