Apple Puffed Oven Pancake

Preheat oven to 400 degrees F. Place butter in a 10-inch ovenproof skillet with flared sides. Place skillet in oven for 3 to 5 minutes or until butter melts. Meanwhile, for batter: In a medium bowl, whisk together eggs, flour, milk, apple pie spice, and salt until mixture is smooth. Immediately pour batter into the hot skillet. Bake for 20 to 25 minutes or until puffed and well browned.

Meanwhile, lightly coat an unheated medium saucepan with nonstick cooking spray. Preheat over medium heat. Add apple slices, brown sugar, and the water. Cook for 4 to 6 minutes or until apples are golden brown and tender, stirring occasionally.

Shortly before pancake is done, prepare caramel sauce: In a small saucepan, stir together brown sugar (see Tips) and cornstarch. Stir in water. Bring to boiling over medium heat, stirring constantly. Boil gently, uncovered, for 3 minutes; remove from heat. Stir in butter and vanilla.

Spoon apple mixture into pancake; drizzle with sauce. Cut into wedges.
