Preheat the air fryer to 300 degrees.

In a large bowl combine the flour, sugar, and baking powder.

Add in the butter, egg, and milk and mix well to combine.

Fold in the cranberries, orange zest, and 1 Tablespoon of orange juice.

Fill muffin cups or cupcake liners half full (you will have enough batter for 12 muffins). You may need to work in batches depending on the size of your air fryer.

Cook for 15 minutes. The muffins will just start to brown. If you want a brown top broil for the last minute of cooking.
