Preheat the oven to 350 degrees and grease a 9x13 inch baking pan with non-stick cooking spray.
In a large bowl, mix cornmeal, flour, sugar, baking powder, and salt together until combined.
In a separate bowl, combine vegetable oil, melted butter, honey, beaten eggs, and milk.
Pour the oil mixture into the flour mixture and stir till just combined. Do not overmix.
Pour the batter into the prepared baking pan and bake in preheated oven for 45 minutes. The top should be starting to brown, and cracks should start to form.
