In this tutorial, we learn how to decorate a carrot cake. First, apply icing all over the top and the sides of the cake. After this, apply sliced pecans to the side of the cake using your hands to press them on. After this, use your icing to create squares in the cake to make equal size pieces. Then, use orange and green icing to create carrot shapes on all of the individual squares. Once you're finished making the carrots, you will be ready to cut this up and serve. If you want more icing, you can apply swirls of icing all around the sides of the cake.
