Preheat the oven to 400 degrees F. Spray a 12 cup muffin pan with cooking spray and set aside.
In a large bowl, whisk together the flour, cornmeal, sugar, baking powder, baking soda, and salt. Set aside.
In a medium bowl, whisk the buttermilk, coconut oil, and eggs until well blended. Pour the liquid ingredients over the dry ingredients and mix with a rubber spatula until combined. Fold in the flavored cheese. Divide the batter evenly among the muffin cups.
Bake for 15 minutes, or until the tops are golden and a toothpick inserted into the center of the muffins comes out clean. Transfer the pan to a rack and cool for 5 minutes. Remove muffins from pan and serve.
