German Pancakes

Preheat oven to 450 degrees. Melt butter in a heavy oven safe dish (I use a 10.5-inch cast iron skillet) over medium heat. Whisk together other ingredients in a large bowl, in the order listed above. Tilt skillet to coat the sides with butter. Pour batter into the skillet and place on the middle rack in the oven. Bake for 20 minutes. When done, the German pancake will be puffy like a souffle and golden brown. Loosen with spatula if necessary and slide from the skillet onto a serving plate. If cooked in a well-seasoned cast iron pan, the pancake should slide out easily. This recipe can be doubled and two pancakes can be baked at once, side by side in the oven.
