1. Bring cream to the boil in a small saucepan, then simmer for 2min or until slightly reduced.
2. Add blue cheese to pan, season to taste with pepper, reduce heat to low-medium then cook, stirring occasionally, for 2-3min or until cheese has melted (don't worry if mixture isn't completely smooth).
3. Spread the gnocchi over the base of a large baking dish, scatter with prosciutto pieces then pour over the blue cheese sauce. Sprinkle with breadcrumbs and parmesan.
4. Bake in 180oC oven for 15-20min or until sauce is bubbling and crumbs are golden.
