Preheat the oven to 400 degrees F. Generously grease a 9-inch baking pan with 1 tablespoon of butter.
In a small bowl, mix the cornmeal, flour, baking powder, sugar and salt. In another bowl, whisk together the melted butter, buttermilk, corn, honey and eggs. Using a rubber spatula, add the wet ingredients to the dry and mix just until combined. Do not overmix.
Pour the batter into the prepared pan. Bake until a toothpick inserted in the center comes out clean, 20 to 22 minutes.
