Preheat the oven to 400 degrees.
Add the oil to a cold 12-inch cast iron pan and put it on the middle rack of the oven as it preheats.
Put all the batter ingredients in a large bowl and mix until just combined.
When the oven reaches temperature, carefully remove the cast iron pan from the oven with oven mitts and gently swirl the hot oil to evenly distribute it around the skillet.
Pour the batter into the pan and listen for the sizzle!
Bake the cornbread on the center rack of the oven for 20-25 minutes, until it is slightly golden brown and a toothpick comes out clean from the center of the cornbread.
Butter the top of the cornbread when it comes out of the oven, if desired.
Wait about 10 minutes, cut into wedges and drizzle with honey and serve.
