Boil the pasta in salted water, but not to full readiness. Drain and put it in a pre-buttered oven dish. Mix with crumbled feta cheese. Beat the eggs with the sugar, milk and cream.
Flavor with vanilla and pour the milk mixture over the pasta. Arrange pieces of butter and put them to bake in a moderately heated oven.
Once the pasta gets a nice tan and solidifies, it is ready. Remove it and while still warm, sprinkle it with powdered sugar.
