• Preheat the oven to 350°F and line a cookie sheet with parchment paper. Set aside.
  

For the cheesecake filling:

• In a large bowl, beat together the cream cheese, yogurt and granulated sugar until smooth.
  
• Add in the egg whites, and vanilla and beat until well mixed. Set aside.
  

For the Oatmeal Crumble:

• In a small bowl, toss together the rolled oatmeal, 1 tablespoon of brown sugar and pinch of cinnamon.
  
• Stir in the melted butter and mix until crumbly and evenly coated.
  

For the Apples:

• Cut each apple in half and use a small knife to cut a large hole in the center of each half, being careful to not go all the way through the bottom of the apple! Rub 1 teaspoon of brown sugar in each apple half and sprinkle with a pinch of cinnamon.
  
• Place the apples onto the prepared baking sheet and divide the cheesecake filling evenly between each half, filling to the top.
  
• Divide the crumble topping evenly between each apple, pressing lightly so that it covers each half.
  
• Bake for 30 minutes, or until the filling just feels set.
• Remove the apples from the oven, and turn it to HIGH broil. Drizzle some maple syrup over all the apples and broil for an additional 2-3 minutes.
  
• DEVOUR!
