Melt 1 tbsp of butter in a microwave for about 15 seconds.

Spread the melted butter on one side of each bread slice. If you prefer both sides buttered, use 2 tbsp of butter.

Cut each slice of bread into 6 equal strips using scissors.

Place parchment paper in the air fryer basket and arrange the bread strips neatly. Cook at 170°C (340°F) for 5 minutes.

While the bread is cooking, mix sugar and cinnamon powder in a ziplock bag.

Once the bread is crispy, remove it from the air fryer. Optionally, flip the strips and cook for an additional 2-3 minutes for extra crispiness.

Place the crispy bread strips into the ziplock bag with the sugar-cinnamon mixture. Shake until evenly coated.
