Add bacon drippings (2 tablespoons) to a 9-inch cast iron skillet and heat in the oven for 5 minutes.
In a mixing bowl, whisk together cornmeal (1 3/4 cups), flour (1/4 cup), sugar (1 tablespoon), baking soda (1 teaspoon), and salt (1 teaspoon) until evenly combined. Make a well in the center and add eggs (2), buttermilk (1 1/2 cups), and vegetable oil (1/4 cup) to the well. Stir everything together just until dry ingredients are moistened.
Using a hot pad, remove skillet from oven. Swirl the bacon drippings in the pan to coat the sides and cover the bottom. Pour batter into batter into hot skillet.
Bake for 16-18 minutes or until the top is golden brown and a toothpick inserted in the center comes out clean (do not overbake or cornbread will be dry!).
Allow cornbread to sit for 10 minutes and cut in skillet or invert onto a plate and serve.
