Cornbread, with Fried Bottom and Sides. Baked in a Cast Iron Skillet

Cornbread.
This Cornbread ends up being fried around the Edges and on the Bottom because your Butter and Oil is hot before adding it together and then back into the frying Pan.
I always use a good Cast Iron Frying Pan but you can use Stainless Steel as well.

INGREDIENTS:  
1 c AP Flour  (I used King Arthur) fluffed and dip method
1/2 c Corn Flour.
1/2 c Corn Meal.
1 tsp Salt.
3/4 Tbsp Baking Powder 
1/4 tsp Baking Soda.
1 1/4 or more c 4% Buttermilk (depends on your flour).
1/3 c salted Butter melted.
1/3 c Vegetable Oil.
1 Egg Beaten 

Optional:   
Choose any of theses. 
2 Tbsp Sugar

1 c Grated Cheese. 
1/4 tsp Red Pepper flakes. 
1/4 c Jalapeño slices. 
1/2 c Corn.
1/4 c Thinly diced Onion Chopped Scallions or Chives. 
2 Tbsp Crumbled Bacon.
 
Preheat Oven or Breville to 450°.  

In a #8 size (medium) Cast Iron Frying Pan, melt the Butter and add Oil. Set aside.
Mix the Beaten Egg with the 1 1/4 c of Buttermilk.  Set aside. (You may need more)
Measure out the Dry Ingredients, Flours and Meals into a small- Medium Mixing Bowl add the Salt. Turn the burner to med Hi (212°) and heat the Butter and Oil until the Butter barely starts to Brown.
Work quickly from here out.
Add the Buttermilk and egg Mixture to the Dry ingredients but don’t stir, then quickly ONLY pour 1/2 (1/3 c) of the hot Butter and Oil mixture into the Batter Mixture. Leave the other 1/2 in the Frying Pan. It will sizzle hard, now quickly and without over stirring, just until almost incorporated, stir to see if you need more Buttermilk…. The Batter will thicken fast, add more Buttermilk if needed but again, don’t over stir…you want it like thick Pancake Batter. No dry pockets, see Pics.
Pour Batter all at once into the hot Oil in the hot Frying Pan (it’ll sizzle again). Spread out to the edges. Scrape the sides with a Spatula and get it all.
Use Oven Gloves…Put the whole Frying Pan into the 450° Oven and set the timer for 15 min. Check for doneness, it may go as long as 20 but watch carefully.  
Brush with Melted Butter on top.
Enjoy!
I love it with Honey Butter or next day heated up, along with Butter, Hot Milk and Honey!
