Preheat the oven to 400°F / 205°C and grease a 9in / 23cm square baking pan.
Whisk 1 cup of fine cornmeal, 1 cup of all-purpose flour, 1 teaspoon of baking powder, ½ teaspoon of baking soda, and ⅛ teaspoon of salt in a large bowl.
In another bowl, whisk ½ cup of melted unsalted butter, ⅓ cup of brown sugar, 2 tablespoons of honey, 1 large egg, and 1 cup of buttermilk until smooth.
Whisk into the dry ingredients until just combined. Pour into the pan and bake for about 20 minutes, until golden and a toothpick comes out clean.
