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.
In a large mixing bowl, whisk the baking powder, cornmeal, salt, sugar, flour and baking soda together. Make a small well in the middle and add the eggs and buttermilk.
Stir until fully combined. Add the melted butter and stir until just mixed. Put the batter into the hot skillet. You will hear it sizzling when you put it in, this is a good thing.
