Preheat the oven to 350°F
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 together the flour, baking soda, nutmeg, and cinnamon.
Stir these dry ingredients into the zucchini mixture. Stir in raisins.
Coat each muffin cup in your muffin pan with a little butter or vegetable oil spray.
Use a scooper to distribute the muffin dough equally among the cups, filling the cups up completely.
Bake on the middle rack until muffins are golden brown, and the top of the muffins bounce back when you press on them, about 25 to 30 minutes.
Test with a long toothpick or a thin bamboo skewer to make sure the center of the muffins are done.
Set on wire rack to cool for 5 minutes.
Remove muffins from the tin let cool another 20 minutes.
