Place the uncooked macaroni into the crockpot.
Add the cubed Velveeta cheese, shredded cheddar cheese, evaporated milk, whole milk, and butter.
Sprinkle in the salt, black pepper, and optional paprika and garlic powder for added flavor.
Stir all the ingredients together until well combined.
Cover the crockpot with the lid and cook on low for 2 to 3 hours, stirring occasionally to ensure even melting and prevent sticking.
After 2 hours, check the mac and cheese. If it’s too thick, add a little more milk to reach your desired consistency.
Once the cheese is fully melted and the sauce is creamy, your mac and cheese is ready to serve. Enjoy!
