This is such a fun recipe to create and watch it rise in the oven!
Rub the inside of a cast-iron skillet lightly with a paper towel dipped in vegetable oil. Put in a 450 degree oven while the oven preheats, being careful to check often because the oil will probably start to smoke.
While the oven preheats, whisk the eggs in a medium bowl. Sift the flour twice, adding the salt on the second time. Add the flour mixture to the eggs, a little each time, whisking after each addition, until you have added all the flour mixture. Add the milk in the same manner, a little at a time. Slowly do the same with 2 tablespoons of melted butter, being careful not to scramble the eggs.
Remove the hot skillet from the oven and melt the remaining 2 tablespoons of butter in the skillet. Immediately pour in the pancake batter and return to the oven for 20 minutes.
Remove from the oven. Using a spatula, carefully remove the pancake from the skillet and place on a serving plate. Right before serving, dust with powdered sugar. Serve with the Maple Glazed Fried Apples.
While the pancake is baking, melt the butter in a medium skillet over medium heat. Add the apples, brown sugar and cinnamon. Cover the skillet and cook, stirring often, for about 10 minutes over low heat until the apples are tender.
