In a small saucepan combine the heavy cream, butter, and cream cheese. Bring to a boil and then immediately turn the heat to low and simmer for 2 minutes.
Add in garlic and simmer for a minute or 2.
Add in parmesan cheese and allow entire mixture to simmer for 15 minutes or until smooth. Whisk or stir occasionally. Your sauce will begin to thicken.
Once done, pour over cooked pasta and add in chicken, greens, broccoli, or eat as is!
