Caramel Apple Cheesecake Bars with Streusel Topping

2 cups all-purpose flour
1/2 cup firmly packed brown sugar
1 cup (2 sticks) butter, softened
2 (8-ounce) packages cream cheese, softened
1/2 cup sugar, plus 2 tablespoons, divided
2 large eggs
1 teaspoon vanilla extract
3 Granny Smith apples, peeled, cored and finely chopped
1/2 teaspoon ground cinnamon
1/4 teaspoon ground nutmeg
Streusel topping, recipe follows
1/2 cup caramel topping
Preheat oven to 350 degrees F.
In a medium bowl, combine flour and brown sugar. Cut in butter with a pastry blender until mixture is crumbly. Press evenly into a 13 by 9 by 2-inch baking pan lined with heavy-duty aluminum foil. Bake 15 minutes or until lightly browned.
In a large bowl, beat cream cheese with 1/2 cup sugar in an electric mixer at medium speed until smooth. Then add eggs, 1 at a time, and vanilla. Stir to combine. Pour over warm crust.
In a small bowl, stir together chopped apples, remaining 2 tablespoons sugar, cinnamon, and nutmeg. Spoon evenly over cream cheese mixture. Sprinkle evenly with Streusel topping. Bake 30 minutes, or until filling is set. Drizzle with caramel topping.
Streusel Topping:
1 cup firmly packed brown sugar
1 cup all-purpose flour
1/2 cup quick cooking oats
1/2 cup (1 stick) butter, softened (I did this in addition to the 2 sticks that I used in the crust)
In a small bowl, combine all ingredients. Yield: approximately 3 cups
