Preheat oven to 350 degrees F.
Start by greasing your loaf pan(s) with butter or vegetable oil.
Grate 1 medium-large zucchini into a small bowl and set aside.
Add all of the dry ingredient to a large mixing bowl and whisk the ingredients until thoroughly mixed.
In a separate bowl, crack the eggs and scramble them, then add the wet ingredients in and mix.
Add the wet ingredients to the dry ingredients and mix until the batter forms and the lumps are reduced.
Add the grated zucchini and mix it in.
If you are going to add chocolate chips fold them in now. To make zucchini bread with walnuts – chop halved walnuts and fold them in at this time.
Scoop the batter into your bread loaf about half way full or a touch more.
Place in the oven and cook for 35-40 minutes at 350 degrees F.
When the timer goes off check it for some golden brown tones forming and a large crack down the center of the top. When you see the crack and golden brown color it is done but you may also check the center with a tooth pick. When the tooth pick is removed it should come out clean.
Allow for the bread to cool and then slice and spread with butter.
