Heavily butter the baking dish and set aside.
Pour the milk into a saucepan and heat it to “almost” boiling.
Add a pinch of salt to the milk.
Pour in the semolina flour, stirring continuously with a whisk.
Cook for 15 minutes over low heat, stirring continuously with a wooden spoon or non-metal spatula.
Pour the mixture into a bowl to cool.
Add 2 ounces of the cheese and the egg yolks and mix carefully.
Pour the mixture onto a baking sheet or parchment paper and spread it out with a slightly wet spatula, until it is about ½ inch thick.
Let it cool.
Cut the gnocchi with a 2 inch diameter round pastry cutter.
Knead the scraps together and cut out more discs until the ingredients are finished.
Arrange the gnocchi in a buttered baking dish, laying them flat and overlapping each row slightly.
Sprinkle the top with the remaining ounce of cheese
Place the baking dish in a preheated oven at 400° F for about 20 minutes or until they are well browned. After 20 minutes, if you want the gnocchi more browned, turn on your broiler and watch closely for 5 minutes making sure it doesn’t burn.
