While the water is heating up, start warming up the milk in a separate pan.
Little by little, add the four pieces of cheese, previously cut into small pieces. Start by adding harder types of cheese first and add the cream cheese and gorgonzola in the end.
Keep stirring until completely melted and mixed.
When the water boils, add some salt in the water and throw in the gnocchi, and cook for 2-3 minutes.
When the gnocchi are cooked, drain the pasta and throw them into the pan with the cheese sauce and mix carefully. Serve, adding pepper on top first.
