Grease an 8-inch square pan. In a large bowl, whisk together the flour, cornmeal, baking powder and salt. Stir in the milk, maple syrup, egg and butter. Mix well to combine.
Pour into the prepared pan, place in the oven, and bake for about 20 minutes.
Remove from oven, cool, cut into squares, and serve.
Keep leftovers in a tightly sealed container in the fridge for up to 5 days.
