Filling: Combine apples and butter in a small saucepan. Cook 5-10 minutes over medium heat. Stir in the sugar and spices. Cover and simmer until tender.
While the filling cooks, preheat oven to 450°. Place 1 TBS butter in a 10 inch oven-proof skillet and place the skillet in the oven to heat. In a medium-sized mixing bowl, beat the eggs. Add milk and vanilla. Gradually mix in the flour until blended. Pour the batter into the heated skillet. Bake 10-15 minutes or until puffed and golden brown. Slice the pancake in wedges, top with apple slices and a dusting of powdered sugar. 4 servings.
