In a large bowl, whisk together sugars and eggs until smooth. Stir in grated carrots and vegetable oil.
3/4 cup granulated sugar, 1/4 cup brown sugar, 2 eggs, 2 cups grated carrots, 1/2 cup vegetable oil
Add flour mixture and walnuts to wet ingredients, mixing just until fully incorporated and no dry bits remain.
1/2 cup chopped walnuts
Pour batter into prepared loaf pan, spreading to the edges and corners. Bake for about 60 minutes, until golden and a toothpick inserted in the center only has moist crumbs. Let cool in the pan a few minutes before removing to a wire rack to cool completely.
Notes
Grate the carrots using the medium holes on a box grater.
A 9x5-inch pan may be used; the bread will not have as high of a dome.
You can add 1/4 cup applesauce or drained crushed pineapple for added sweetness and moisture.
