Start by adding the flour, baking powder, sugar, and salt to a mixing bowl and mix well.
Then mix in eh buttermilk, eggs, vanilla extract, and melted butter.
Mix well.
Spray your muffin tins with non-stick cooking spray or olive oil spray.
Pour your muffin mixture into the prepared muffin tins.
Add a few blueberries on top.
Set the temperature to 320 degrees F for 8 to 12 minutes, air fryer setting.
Check them when they come out, mine were fully cooked, so I removed the muffin tins and placed them on the counter to cool slightly. If yours are not cooked (remember every air fryer is different), add a few more minutes.
Plate, serve and enjoy!
