Preheat the oven to 400°F. Spray a 9-inch round pan with nonstick spray.
In a medium bowl, whisk together the flour, cornmeal, sugars, baking powder and salt. In a separate bowl, whisk together the remaining ingredients. Add the wet ingredients to the dry ingredients and stir just until moistened.
Scrape the batter into the prepared pan and bake for 20 to 25 minutes, or until a toothpick inserted into the center comes out clean. Cool slightly and slice into wedges.
