Preheat oven (electric cooker: 200 °C/circulating air: 175 °C/gas: see manufacturer). Heat butter in a large pan. Fry uncooked gnocchi for approx. 5 minutes, turning them over. Season to taste with salt, pepper and nutmeg.
Grate the whole cheese and sprinkle over the gnocchi. Bake in a hot oven for about 5 minutes. Wash the chives and cut into small rolls. Spread slices of bacon on the gnocchi and sprinkle with chives.
If there is still some whipped cream in the fridge, simply pour it over the gnocchi before gratinating.
