Separate dough into eight rolls. Place four rolls on a greased baking sheet. Using a 2-inch biscuit cutter, cut ¾ inch into both sides of remaining rolls to form ears and bow ties. Place ears at the top and a bow tie below each cinnamon roll; pinch to attach. Slightly flatten rolls.
Bake at 400 degrees for 8–10 minutes or until golden brown. Set aside 1 1/2 teaspoon icing. Spread remaining icing over bunnies. Place a baking bit in the center of each bow tie; add remaining baking bits for eyes. Place a jelly bean in each center for nose; attach licorice pieces for whiskers.
Tint reserved icing pink with red food coloring; pipe mouths and outline ears. Pipe edges of bow ties with decorating gel.
