Oven-Baked Dutch Apple Pancakes

Place a 10" cast iron skillet inside oven and preheat to 475 ºF. In a small saucepan over low heat, stir together apple pie filling and cinnamon. Heat through. In a medium mixing bowl, whisk together the eggs, milk, flour, sour cream, lemon zest, nutmeg and salt until frothy. Remove the hot skillet from the oven and reduce the oven temperature to 425 ºF. Add butter to the hot skillet and melt. Working quickly, pour batter into the skillet and return to hot oven. Bake until golden and puffed, approximately 12 minutes. Remove from oven and promptly top with warm apple pie mixture. Dust with confectioners sugar.
