Quick and Easy Alfredo Sauce

I didn't totally followed the recipe. I had to adjust and improvise on the ingredients. I used heavy cream, mozz cheese, butter, pepper, and chives, not very good.

Heavy Cream Alfredo Sauce:
1/4 cup butter
1 cup heavy cream
1 clove garlic, crushed
1 1/2 cups freshly grated Parmesan cheese
1/4 cup chopped fresh parsley

Melt butter in a medium saucepan over medium low heat. Add cream and simmer for 5 minutes, then add garlic and cheese and whisk quickly, heating through. Stir in parsley and serve.

Cream Cheese Alfredo Sauce:
1/2 cup butter
1 (8 ounce) package cream cheese
2 teaspoons garlic powder
2 cups milk
6 ounces grated Parmesan cheese (about 1 2/3 cup)
1/8 teaspoon ground black pepper

Melt butter in a medium, non-stick saucepan over medium heat. Add cream cheese and garlic powder, stirring with wire whisk until smooth. Add milk, a little at a time, whisking to smooth out lumps. Stir in Parmesan and pepper. Remove from heat when sauce reaches desired consistency. Sauce will thicken rapidly, thin with milk if cooked too long. Toss with hot pasta to serve.
