Cut the crust off of the slices of bread and then take a glass or rolling pin to flatten the bread.
Use a butter knife and spread a thin layer of butter over both sides of the bread.
Add the cheese slices to the bread and then roll them.
Place the grilled cheese roll ups into the prepared air fryer basket. Cook on 360 degrees Fahrenheit for 5-6 minutes, flipping the roll-ups halfway through.
Serve immediately.
