Preheat oven to 400 F.
Generously butter a medium-sized cast iron skillet. (At least 10" across.)
Combine flour, corn meal, 3/4 cup sugar, salt, and baking powder in a mixing bowl.
Add wet ingredients on top, stir just until combined.
Add batter to buttered cast iron skillet. Scatter 1 Tablespoon of sugar on the top of the batter to form sparkly crust. Bake at 400 degrees for 25-30 minutes.
Remove from oven when the corn bread is just baked. It should have some moist crumbs on a toothpick or cake tester but not actually be wet. Edges will start to brown and pull away slightly from the sides of the pan. Overcooking will make it dry.
To make the honey butter, stir butter and honey together until mixed.
