Bring a large enough pot of water to the boil. Once boiling add salt and cook the pasta 2 minutes earlier than the packet directions. (It will finish cooking in the sauce after)

Melt the butter, add the cream cheese, whipping cream and fresh black pepper.

Simmer for 3 to 5 minutes until the cream is little thicker before adding the pasta. If you cream is already getting thick simply add a dash of pasta water or milk to thin it out and then your pasta. If you cream look like it's not getting thick just wait it will thicken up so try not to add the pasta too early. (I have notes in this post on this if you need).Also it will thicken as it stands so keep the milk near if you need to thin it out.
