In a large bowl, whisk together the dry ingredients.
Add wet ingredients to the bowl and mix until just combined.
Spray a round 8-inch cake pan with cooking spray and pour in the batter. Use a spatula to even out the top, then cover with foil.
Place your pan into the air fryer at 360°F for 25- 30 minutes or until fully set. If an inserted toothpick comes out clean, the cornbread is done.
Remove from the air fryer and let it cool in the pan slightly before slicing.
Serve warm with butter, honey, or jam.
