It could be the two full sticks of butter that makes the cornbread so good. This recipe won't be found on Cooking Light anytime soon but it is worth the calories.
2 sticks melted butter (you can go with less, but I tend to stay with 1 ½ to 2 sticks)
2 eggs slightly beaten
1 ¼ cup of milk
2 cups Bisquick
¾ cup sugar
¾ cup cornmeal
½ teaspoon baking soda
Combine everything and mix for a couple minutes. Bake at 350 for 30-40 minutes.
