Preheat your air fryer to 350°F for 5 minutes.
In a large mixing bowl, combine the cornmeal, flour, sugar, baking powder, and salt.
In another bowl, whisk together the milk, melted butter, and eggs until well combined.
Pour the wet ingredients into the dry ingredients and mix until just combined. Be careful not to overmix.
Grease a 7-inch round cake pan that fits into your air fryer basket.
Pour the batter into the prepared cake pan, spreading it evenly.
Place the cake pan in the air fryer basket and cook at 350°F for 18-22 minutes, or until the cornbread is golden brown and a toothpick inserted into the center comes out clean.
Once done, carefully remove the cornbread from the air fryer and let it cool in the pan for a few minutes before slicing and serving.
Serve warm with butter, honey, or your favorite toppings. Enjoy!
