Preheat the oven to 350F. Grease a 12 count muffin tin and set it aside. In a large bowl, whisk together the oats, baking powder, cinnamon, nutmeg and salt. In a separate bowl, whisk together the milk, yogurt, eggs, vanilla and brown sugar. Pour the wet ingredients into the dry and mix until everything is incorporated. Then fold in the shredded carrot, raisins and pecans.
