Combine the dry ingredients in a large bowl, stirring until well mixed.
Whisk together the wet ingredients (including brown sugar and grated carrot) in a small bowl.
Pour the wet ingredients into the dry, and mix just until blended.
Spray both grids of a preheated waffle iron with oil. Pour or ladle the batter into the center of the iron, covering no more than two-thirds of the iron’s surface for the first waffle. Adjust the amount as needed for subsequent waffles.
Bake each waffle for 4 to 6 minutes, or until it can be removed easily, spraying the waffle iron grids with oil prior to each waffle.
