Melt the butter but do not let it brown. Add garlic and sautee until it starts to turn light brown.(feel free to add more garlic if you love garlic)
Add the whipping cream and mix well to incorporate the butter with the cream. (I sometimes lightly use my wisk to make sure it mixes well.) Stir for 2-3 minutes. Add the parmesan cheese and stir quickly as it will start to thicken right away.
