In a large mixing bowl mix together the bisquick, cornmeal, white sugar, and baking powder.
Next add the milk and the eggs to the mixing bowl. Mix for about 30 seconds just until the batter is mixed together.
Add the melted butter to the mixing bowl and mix for about another 30 seconds or just until everything is mixed completely.

Bake cornbread muffins for 14 to 16 minutes.
Cooking Tips: I suggest to only mix batter for about 30 seconds after adding the different ingredients to prevent over mixing batter which will make the batter tough... Which equals tough cornbread muffins.....
