Preheat the oven to 400°F. Lightly grease an 8x8 baking dish with butter and set it aside.* You can also line your baking dish with parchment paper to make things easier if you prefer.
In a large bowl, whisk the dry ingredients together (all-purpose flour, cornmeal, sugar, baking powder and salt).
In a separate medium bowl, whisk the melted butter, vegetable oil, milk, and egg together until combined.
Now pour the wet ingredients into the dry ingredients and gently stir everything together. Be careful not to over mix at this point.
Pour the cornbread batter into the baking dish and bake for 23-25 minutes or until cooked through and golden brown on top. Allow the cornbread to cool then slice. You can slice it into 9 large pieces or smaller pieces depending on how many people you are serving. Serve with butter or honey drizzled on top. Enjoy!
Notes
You can also make this cornbread in a 9-inch or 10-inch cast iron skillet at the same oven temperature for the same time.
