Step 1

Grease a 7-inch round cake pan with butter; set aside.

Step 2

Add 6 tablespoons of the butter to a large microwave-safe bowl and microwave until just melted, 30 to 60 seconds. Let cool slightly. Whisk in the buttermilk, eggs and vanilla until smooth. Whisk in the cornmeal, flour, sugar, baking powder, salt, and baking soda until smooth and well combined (it’s OK if a couple small lumps remain).

Step 3

Pour the batter into the prepared cake pan and place in the basket of a 6-quart air fryer. Cook at 350 degrees F until deep golden brown and a toothpick inserted in the center comes out clean, about 25 minutes. Let cool in the pan for 5 minutes, then invert onto a wire rack.

Step 4

While the cornbread is cooking, stir together the honey and remaining 4 tablespoons butter in a small bowl until combined. Enjoy the cornbread warm or at room temperate, with a smear of honey butter and a sprinkle of flaky sea salt, if desired.
