Preheat your oven to 180°C (350°F). Lightly coat a 12-cup standard muffin tin with melted butter to prevent sticking.
In a large mixing bowl, combine the dry ingredients: all-purpose flour, cornmeal, sugar, baking powder, and salt. Stir briefly to blend them together.
In a separate bowl, whisk the wet ingredients: melted butter, milk, eggs, and creamed corn. Make sure everything is well combined.
Slowly pour the wet mixture into the bowl with the dry ingredients. Stir gently until the batter is smooth and well-mixed, ensuring there are no lumps.
Carefully spoon the batter into the prepared muffin tin, filling each cup to the top to use up all the batter.
Place the muffin tin in the preheated oven and bake for about 20 minutes, or until the tops are a rich golden brown.
Once baked, remove the muffins from the oven. Optionally, brush the tops with extra melted butter for added flavor. Allow the muffins to cool in the tin for about 5 minutes before transferring them to a cooling rack. Enjoy warm or at room temperature.
