Preheat oven to 375 F on the BROIL setting, or LOW BROIL, and a 10 or 12 inch cast iron skillet on the stove top on MEDIUM-LOW with 1 tbl oil of choice.
Whisk all ingredients together and choice of optional add-ins (fold in bulky items like apples or chives after ingredients are mixed well).
Once skillet is preheated, pour in batter and turn heat down to LOW
Cook on stove top for a good 7-10 min and pancake has set up completely with air bubbles all over the surface
Once surface is mostly covered in air bubbles, place skillet in oven on middle rack and broil for 3-5 min, keeping a close eye on the pancake so it doesn't burn. (I'm a seasoned expert at this. The burning part.) Cook until done in the center, or a toothpick comes out clean.
Slide the pancake out from skillet onto a cutting board with the aid of a metal spatula.
I use a pizza cutter to slice the round into 8 servings.
