Combine butter, buttermilk, eggs, and vanilla in a large mixing bowl. In a separate bowl, mix all dry ingredients together before mixing wet and dry ingredients just until combined.

Stir in the zucchini, and mix just until incorporated. Let mixture sit and rest for at least 15 minutes. Preheat waffle iron {medium heat if you have an adjustable waffle iron} and grease with butter if necessary.

Pour 1/2 cup of mix onto each square, close and let cook until no longer doughy in the middle & nice & golden brown. Serve with butter or syrup or powdered sugar or butter and syrup and powdered sugar. You decide the level of sugar high you want.
