Lightly coat a 9-inch cast-iron skillet with vegetable oil. Place the skillet in the oven and preheat the oven to 450°F.
Meanwhile, in a large bowl, combine the cornmeal mix, buttermilk, egg, and 1/4 cup vegetable oil. Stir until smooth.
Once the oven has preheated, carefully remove the skillet and pour the batter into the skillet. Return to the oven and bake for 20 to 25 minutes or until golden brown.
