Delicious dark chocolate mousse layered beneath buttery cookies creates the perfect Neapolitan dessert. Plan ahead with this recipe. Making the rich mousse perfectly airy and light takes an eye for detail and a few hours to chill in the refrigerator. Crunchy flakey cookies melt in the mouth with the soft chocolate. Layer each plate with a cookie and a dollop of chocolate mousse, about 4 cookies tall, for a rustic, homey appearance. This is a fabulous recipe to have the kid’s plate; it’s fun for layer, easily individualized, and scrumptious.
