Stir together the flour, sugar, salt, baking soda, and baking powder in a mixing bowl. Make a well and pour in the melted butter. In a measuring cup, beat the egg and buttermilk together before whisking it into the flour mixture.
Heat the skillet over medium flame to melt 1-2 tablespoons of butter; remove from the heat when melted. Pour the batter into the buttered skillet before baking at 375 degrees in a preheated oven for 30 minutes.
Vanilla Honey Butter
To make the vanilla honey butter, whip together softened salted butter, honey, vanilla extract, and a pinch of salt until smooth and creamy. Store leftovers in the fridge.
Notes
*Be careful to measure the flour lightly. You don't want to pack the flour. This cornbread should be light and a little crisp on the outside.
