In one pot, boil the pasta according to the directions on the box (about 10-12 minutes)

In a separate pot, melt the stick of butter over medium-to low heat

Add garlic to the melted butter and cook for 2 minutes

Mix in heavy cream

Stir in room-temperature cream cheese

Continue to cook over medium-low heat until the creamy mixture gently bubbles (not boiling!)

Add in the parmesan mozzarella cheeses

Add salt and pepper to taste

Stir regularly until the cheeses are melted

Stir in drained/cooked pasta to the Alfredo sauce and enjoy! Sprinkle with chopped parsley (optional)
