Add 2 ½ cups milk, butter, garlic powder and water to a medium-sized pot.
Just barely bring to a boil, add the pasta and turn the heat to medium-low. Cook until the pasta is al dente, about 20 minutes, stirring frequently. Make sure the milk doesn’t burn, turn the heat down if needed.
Meanwhile, in a blender add the kale and remaining ½ cup of milk and blend until smooth. If using frozen kale, you likely won’t need the milk. Feel free to add the milk a few splashes at a time to ensure you only use as much as you need to blend the kale into a puree. You don’t want this mixture to be too runny.
Once the pasta is cooked, turn off the heat and add the cream cheese and cheddar cheese. Put the lid on the pot and let sit a few minutes until the cheese has completely melted.
Stir in the kale puree. If the sauce is thin, you can let it sit for a few minutes before serving.
