Preheat the oven to 400 °F. Add the butter to your skillet and place it over medium heat on the stove. Allow the butter to melt and for the pan to warm up.
Once the butter has melted, turn off the heat but keep the skillet on the burner to retain its warmth. In a large mixing bowl, whisk the baking powder, cornmeal, salt, sugar, flour and baking soda together.
Put the batter into the hot skillet. You will hear it sizzling when you put it in, this is a good thing. Bake for 20-22 mins or until it is golden brown and the edges are crispy.
