Pull out a medium/ large cookie sheet and place parchment paper in it.

Take the mac n cheese and spread it evenly all over the cookie sheet. Place in the freezer for at least four hours if not longer. Creamier mac n cheese will take a longer time to freeze than regular mac n cheese.

Take an ice cream scoop and scoop the mac n cheese into small balls.

Roll the mac n cheese balls into flour.

Take the mac n cheese balls covered in flour and dip it in the melted better. And then roll it in the bread crumbs with bacon bits (bacon bits optional). You can repeat this step if you like.

Add some of the balls to the deep fryer (make them in small batches of about 4 to 5 to make sure they get cooked evenly).

Wait around 3 to 4 minutes for each batch. Check to make sure the balls are golden and crispy.

Remove from deep fryer and place on a plate with paper towel.

Serve immediately (and with chives if desired).
