Preheat oven to 400*F. Put an 8 or 10 inch cast iron skillet in the oven to preheat.
Whisk together flour, cornmeal, baking powder, parsley, salt, oregano, garlic powder, and red pepper flakes. Set aside.
In another bowl, stir together yogurt, egg, honey, and tomato sauce. Pour wet mixture into dry mixture and stir until just combined {don't over mix}. Fold in pepperoni, basil, and mozzarella.
Carefully take the skillet out of the oven, and add in butter. Let melt and swirl butter around pan so it's evenly distributed. Pour batter into skillet and bake in preheated oven for 25-28 minutes until done. Enjoy!
Notes
*The batter is really thick, and it won't do much spreading once it's in the skillet
