1Remove the crusts from the bread, then flatten each slice lightly with a rolling pin.
2Place one slice of cheese on each piece of bread and roll tightly into a finger shape.
3Wrap one slice of bacon around each bread roll, making sure it overlaps slightly to stay in place. If needed, secure the end with a toothpick.
4Mix the softened butter with garlic powder and parsley if using, then brush lightly over the rolls.
5Arrange them on a baking tray lined with baking paper or place them in an air fryer basket.
6Bake in a preheated oven at 190°C (375°F) for 18 to 22 minutes, turning once halfway through, until the bacon is crisp and the cheese is melted. Alternatively, cook in an air fryer at 180°C (356°F) for 10 to 12 minutes.
7Let them rest for 2 minutes before serving so the cheese settles slightly.
8Serve hot with ranch, honey mustard, or marinara sauce if desired.
