If you like nuts in your cake, stir 1 1/2 cups toasted chopped pecans or walnuts into the batter along with the carrots. Raisins are also a good addition; 1 cup can be added along with the carrots. If you add both nuts and raisins, the cake will need an additional 10 to 12 minutes in the oven. Below are instructions for using a food processor. **If making 2-9" round cakes, make 1.5-2 of frosting.
