Preheat the oven to 350F (175C) Line muffin tins with paper cups or grease well.
In a large bowl combine the sugar, eggs and vanilla. Stir in the grated zucchini and then the melted butter. In a separate bowl, mix the flours, baking soda and cinnamon. Stir the dry ingredients into the wet ingredients, being careful not to over mix. A few dry streaks of flour are OK. Fill the muffin tins generously, but not over the top or you might get sticking. Bake for 25 minutes (conventional size muffins) about 12 minutes for mini size, or until the tops spring back when pressed.
