This marbled treat will be a hit with ice cream fans. We recommend the three-flavoured Neapolitan ice cream (it’s what makes this recipe so good!) but you can choose whichever flavour you prefer. The sandwiches will firm up once they’ve been frozen. This way, the ice cream won’t leak out when you take a bite. What’s more, the colourful round sprinkles all around the exterior make for a pretty dessert you can’t say «no» to.
