Make cornbread mixture according to package directions or according to the recipe you are following.
Fill silicone muffin liners about 2/3 way full with cornbread mixture.
Place in air fryer basket and cook at 330 °F for 10 minutes. Check on the muffins a couple minutes before cooking time is over to decide if you need to pull them out early or add more time.
Notes
Feel free to use your own favorite recipe with the baking instructions provided, just be sure to check on them towards the end so the muffins don't get burnt. *Viewer Ed recommends substituting a small can of cream corn in place of the milk. This gives you some extra "texture" and flavor to the muffins.
