Whisk together dry ingredients in a large mixing bowl. Mix together liquid ingredients in a smaller bowl, then combine into the dry ingredients and mix well. Stir in carrots and raisins (optional - my husband doesn't like raisins so I split the batter in half to do part with, part without. It doesn't make any difference in the texture of the finished waffles). Following the directions for your particular waffle iron, place the batter in a preheated waffle iron and cook until golden.
Our waffle iron is about 8" across and this batter makes three very large, dense waffles. These are very filling and pair perfectly with berries on the side!
