Here is a quick 3 step technique for making marzipan carrots to decorate your carrot cake

1.To make the marzipan carrots for classic carrot cake (see Classic Carrot Cake), take a quarter-size piece of store-bought marzipan paste (or almond paste) tinted with a few drops of orange food coloring and shape it into a cylinder that’s tapered to a point at one end. Todd Coleman
2.Roll a pea-size amount of marzipan paste tinted with green food coloring between your fingers to form a thin cylinder. Lay that cylinder across the blunt end of the orange cone; use a toothpick to press center of cylinder into top of cone, creating two “leaves.” Todd Coleman
3.Set marzipan carrot aside for 10 minutes to allow its exterior to dry slightly. Then, using a small paring knife, score the surface of the carrot in staggered circular patterns to create natural-looking “wrinkles”; repeat to make 11 more carrots. Todd Coleman
