First, spray the slow cooker with cooking spray so that the mac and cheese does not stick to the sides.
Next, add the cream cheese, butter, milk, evaporated milk, black pepper, jalapeño, and scallions into the slow cooker. Mix all the ingredients to combine.
Now, add the cheddar cheese, hot sauce, and mix well.
Finally, add the dry pasta and mix really well to combine all the ingredients.
Cover and turn the slow cooker on low for 3 hours.
When finished topped with more scallions. Also optional for crunchy texture add crushed "Cheez-It" on top.
