Preheat a 10 inch cast iron frying pan in a 350 degrees oven.
Whisk together the cornmeal, flour, baking powder, sugar, garlic, onion powder, and salt.
Add remaining ingredients (only 3 tbsp EVOO) and stir until just combined.
Remove pan from oven and add 1 tbsp EVOO to pan - spreading to cover. Pour batter into pan and return to oven.
Bake for 35 minutes or until golden brown.
Notes
You can also add 1 chopped jalapeño, 1/4 cup more cheese, and approximately 1/4 cup more chopped onion without drastically changing the recipe. You can also substitute bacon drippings for the EVOO if desired.
