    On large rectangular serving plate, place cake layer, rounded side down. Remove liners from 2 cupcakes, and cut them in half. Spread a small amount of frosting on cut side of each cupcake half to keep them in place. Arrange cupcakes cut sides down as shown in photo to create back and side fins, discarding extra cupcake half. Place 2 marshmallows on front of cake to create mouth and 3 marshmallows on top of fish to create top fin. Cut remaining marshmallow in half crosswise to create eye. Use small amount of frosting to "glue" a blue candy on for pupil; set aside.

    Frost body for fish purple and fins and marshmallows pink. Use enough frosting on fins to shape cupcakes into desired fin shape. Place marshmallow eye on cake. Use remaining frosting and candies and cereal to decorate remaining cupcakes as desired.

Tips from the Betty Crocker Kitchens

  • tip 1
    Freeze the extra cupcakes unfrosted tightly wrapped up to 2 months. Loosen wrap, and thaw at room temperature 2 to 3 hours.
  • tip 2
    *For all chocolate and devil's food cake mixes, use only 1 cup water.
