Preheat oven to 400F. Lightly grease a 9-inch cast iron skillet or a 9-inch square baking dish.
In a large bowl, whisk maple syrup, sugar, eggs, vegetable oil, pumpkin, and buttermilk until smooth. In a separate medium bowl, combine flour, cornmeal, pumpkin pie spice, baking powder, baking soda, and salt. Fold flour mixture into liquid until batter is just combined.
Spread batter evenly into prepared pan. Bake cornbread at 400F 20-25 minutes until golden-brown and a toothpick comes out clean.
Cool cornbread slightly on a wire cooling rack before cutting into wedges. Serve cornbread warm with butter and maple syrup if desired. Enjoy!
