Before you start, it’s a good practice to assemble all your ingredients. It saves time and makes the cooking process a breeze. Imagine having everything out on the counter, ready to go!

In a medium nonstick saucepan, melt the unsalted butter over medium heat. Keep an eye on it; you don’t want it to brown. This butter will become the foundation of your sauce, giving it that luscious mouthfeel.

Once the butter has melted completely, add the cream cheese and garlic powder to the pan. Using a whisk, mix the two ingredients together until they form a smooth blend. This should only take a few minutes. You're looking to dissolve that cream cheese into the butter nicely.

Now, it’s time to start adding the milk. Pour it in slowly, whisking well with each addition to eliminate lumps. Don’t rush this step. Cooking should be enjoyable, and getting a lump-free sauce is key to that delightful texture we all want.

After all the milk has been incorporated and the sauce is smooth, stir in the grated Parmesan cheese and black pepper. It may start to thicken, and that’s a good sign! Keep stirring until the cheese has melted completely and the mixture gets creamy.

Remove the saucepan from the heat once you have reached the desired thickness. If your sauce gets too thick, don’t fret! You can always thin it out with a splash more milk, stirring until you achieve that silky texture.

Finally, toss your alfredo cream cheese sauce with freshly cooked pasta of your choice. Make sure the pasta is hot and well-drained for the best possible combination. Get ready to serve up a bowl of pure happiness!
