Cream oil and sugar; add eggs and beat well. Sift flour, cinnamon, salt and baking soda together. Add to mixture and beat well. Fold in grated carrots and nuts. Grease and flour 3 layer cake pans. Bake in a preheated 325 degree oven for 45 minutes or until cake is done. When cake has cooled, ice cake.
To make icing: Combine all the ingredients and beat well. Ice between layers, top and sides of carrot cake. Keep cake in a cool place so icing doesn't melt.
