Aunt Betsey's Carrot Cake

I've had this recipe of my aunt's for carrot cake for years and love it each time I make it.

Carrot Cake

1 1/2 c cooking oil
2 c sugar
4 eggs
2 tsp baking powder
2 tsp baking soda
2 c flour
2 tsp cinnamon
1/2 tsp salt
1 tsp vanilla
2 c chopped walnuts
3 c grated carrots

Blend oil and sugar, add eggs one at a time. Beat well after each addition. Combine dry ingredients, add to creamed mixture. Stir in remaining ingredients. Bake in a 13" x 9" pan, 50-60 minutes, 350* oven.

Frost with cream cheese frosting.
