This very wicked, very popular pink and green layer cake recipe, from the kitchen of recipe developer Jennine Rye, is an exuberant homage to the beloved musical, one sweet, soft sponge cake at a time.
This recipe has several components ... discard parchment. Place one cake layer on a cardboard cake round or plate. Pipe a 1/2-inch-tall border of icing around edge of first cake layer.
