Best alfredo sauce ever (no I am serious the best!)

Melt 2 cubes of butter in large pot. When melted, add 1/2 block cream cheese (4oz) cut into cubes. Whisk together and add 2 pints(1 quart) whipping cream, 1 1/2 cup fresh grated Parmesan cheese, 1 tsp. garlic salt, 1 tsp garlic powder, 2 little sprinkles of nutmeg and freshly ground pepper to taste. Heat thoroughly and pour over 2 lbs pasta(drained but NOT rinsed)

* you can thicken the sauce more if you like by adding Parmesan cheese powder from a jar.
