Wash, peel, deseed, and shred your zucchini.
Let the zucchini drain, even manually press out the moisture from them.
Preheat your oven to 350 degrees Fahrenheit.
Grease a loaf pan with butter, and flour it evenly everywhere. Beat the eggs with sugar, melted butter, and vanilla. Add all the ingredients, except the zucchini, and mix them well.
Let it sit for 5-10 minutes before folding in the zucchini.
Gently mix them in. Depending on the size, the bread mixture will probably fill two loaf pans comfortably.
Bake them for 50 minutes to an hour in a preheated, 350-degree oven.
Let them come to room temperature before serving.
Never cover them while still hot.
