Butter cast iron skillet, place in oven and preheat at 400°

Mix all dry ingredients together well. Cut cold butter into small cubes, use your hands to incorporate butter into mixture very well. I find starting with my knuckles gets it going, then I mash it with my finger tips. It should hold together when you make a fist with it.

Make a well in center, add 2 slightly beaten eggs and both milks.

Use a baking spatula and fold batter over itself until all is blended.

Carefully take cast iron out of your preheated oven and add mixture. Bake for 25 to 30 minutes or until top is golden and tooth pick comes out clean.
