Prepare the Ice Cream: Scoop out large balls of ice cream (about 1 cup per ball). If the ice cream is too soft to scoop, place it in the freezer for a few minutes to firm it up.
Coat the Ice Cream: Place the Cinnamon Toast Crunch cereal in a ziplock bag and crush it into small pieces using a rolling pin. Transfer the crushed cereal to a large plate. Roll each ice cream ball in the crushed cereal, pressing it into the ice cream to coat it thoroughly. You may need to roll the ice cream in the cereal twice for a thicker coating.
Freeze the Ice Cream: Place the coated ice cream balls on a parchment-lined baking sheet and freeze them for 3-4 hours (or overnight).
Preheat the Air Fryer: Preheat your air fryer to 400°F (200°C) for 5 minutes.
Air Fry the Ice Cream: Once the air fryer is preheated, remove the ice cream balls from the freezer and transfer them to the air fryer basket. Air fry at 400°F for 2 minutes until the coating is golden and crispy while the ice cream stays frozen inside.
Serve Immediately: Remove the ice cream balls from the air fryer and serve immediately. Top with chocolate syrup, whipped cream, caramel syrup, or maraschino cherries, as desired.
