In a large bowl combine the whole wheat flour, oats, baking powder, baking soda, cinnamon, ginger and nutmeg.
In a separate bowl, combine the carrots, oil, maple syrup, egg, milk and vanilla. Whisk until well combined.
Pour the wet ingredients into the dry ingredients bowl and mix well. Add the raisins to the muffin mixture and stir.
Spray the muffin tin with cooking spray. Using a 1/4 measuring cup, evenly divide the mixture between 6 muffin slots (about 3/4 full). Bake for 12 minutes. Set aside to cool.
