Preheat oven to 350 F. Spray muffin tins. (My suggestion: spray paper muffin cups - low fat muffins tend to stick.)
Combine dry ingredients in a large bowl. Stir in carrots and drained raisins.
Beat eggs with oil. Stir into flour mixture. Divide batter evenly among 12 tins. Bake for 30-35 minutes or until toothpick inserted in center of muffin comes out clean.
