Custard-filled cornbread bakes with a layer of soft custard in the center, making it delicious and moist. Your family will ask for this sweet cornbread again and again!
Heat the oven to 350 F. Put the butter or drippings in a 9-inch square baking pan or 10-inch iron skillet and place it in the oven. When the butter is melted and sizzling, carefully remove the pan or skillet to a rack.
Meanwhile, combine the cornmeal, flour, sugar, baking soda, and salt in a large mixing bowl; whisk to blend.
In a separate bowl, whisk 1 cup of milk with the buttermilk and eggs until smooth and well-blended.
With a whisk or electric mixer, combine the wet and dry ingredients to make a smooth batter.
Pour the batter into the prepared pan or skillet, then slowly pour the remaining 1 cup of milk over the batter.
Bake the custard-filled cornbread for 35 to 45 minutes, until the top is golden brown and the center is firm to the touch.
