Heat a 12-inch cast iron skillet (or ovenproof), over medium heat and add the butter. Cook, occasionally stirring until foamy and the butter turns a deep nut brown. Immediately pour off into a large bowl to cool.
1 1/2 Sticks Butter
Turn the burner off and place the skillet back on the burner.
Whisk the honey, maple syrup, and sugar into the butter, then whisk in the buttermilk. Once cooled, whisk in the eggs. Switch to a wooden spoon and stir in the cornmeal, flours, baking powder, salt and baking soda.
1/4 Cup Honey, 1/4 Cup Maple Syrup, 2 Tablespoons Sugar, 2 Cups Buttermilk, 2 Eggs, 1 1/2 Cups Cornmeal, 1 Cup Flour, 1 1/2 Tablespoons Baking Powder, 3/4 teaspoons Salt, 1/2 teaspoon Baking Soda
If the skillet is no longer hot, reheat it briefly on the stove for a few minutes then scrape batter back into it. Bake until the top is golden brown and a toothpick comes out clean, 30 to 40 minutes.
