Dutch Baby - German Apple Pancake

Ingredients

• 4 eggs
• 1/2 cup unbleached all-purpose flour (I used whole wheat.)
  
• 1/2 teaspoon baking powder
• 1 tablespoon sugar
• 1 pinch salt
• 1 cup milk (I used soy milk.)
  
• 1 teaspoon vanilla extract
• 2 tablespoons unsalted butter, melted (I used salted butter.)
  
• 1/2 teaspoon ground nutmeg
• 
  
• 1/4 cup unsalted butter
• 1/2 cup white sugar, divided (I left out the second 1/4cup.)
  
• 1/2 teaspoon ground cinnamon
• 1/2 teaspoon ground nutmeg
• 1 large tart apple - peeled, cored and sliced

Directions

1. In a large bowl, blend eggs, flour, baking powder, sugar and salt. Gradually mix in milk, stirring constantly. Add vanilla, melted butter and 1/2 teaspoon nutmeg. Let batter stand for 30 minutes or overnight.
2. Preheat oven to 425 degrees F (220 degrees C).
3. Melt butter in a 10 inch oven proof skillet, brushing butter up on the sides of the pan. In a small bowl, combine 1/4 cup sugar, cinnamon and 1/2 teaspoon nutmeg. Sprinkle mixture over the butter. Line the pan with apple slices. Sprinkle remaining sugar over apples. Place pan over medium-high heat until the mixture bubbles, then gently pour the batter mixture over the apples. (I sauteed the apples in the mixture, without the remaining sugar, until they started to soften.)
   
4. Bake in preheated oven for 15 minutes. Reduce heat to 375 degrees F (190 degrees C) and bake for 10 minutes. Slide pancake onto serving platter and cut into wedges.
