Preheat the oven to 350 degrees and grease a 12-muffin pan.
In a medium bowl, mix together the dry ingredients and set aside.
In a large bowl, stir together the wet ingredients (everything except the carrots) until well combined. Add the dry ingredients and stir until just combined.
Fold in the carrots.
Transfer the batter to the muffin pan. Bake for 18 to 20 minutes, until a toothpick inserted in the center of a muffin comes out clean.
