To decorate each cupcake, pipe 1-inch (2.5 cm) mound of frosting on 1 side of cupcake to look like head of turkey. Make eyes with white decorating icing and brown decorating gel; add candy corn for beak. To make feathers, pipe frosting on opposite side to hold candy corn; place candy corn upright on frosting to look like feathers. Sprinkle chocolate candy sprinkles near head and at base of feathers. If desired, add candy corn at base of cupcake for feet. Store loosely covered.
