Instructions
Crust
Preheat oven to 350 degrees F (175 degrees C) and grease the bottom and sides of a 9"x13" cake pan. In a large bowl, mix all the ingredients for the crust except the butter. Once well combined, add in melted butter and stir well. Press into the bottom of the cake pan (no need to press it up the side since these are making cheesecake bars). Bake in preheated oven for 10 minutes.
Cheesecake Filling
In a large bowl, combine cream cheese and sugar. Mix at medium speed until smooth, then add flour until well combined. Beat in eggs one at a time, mixing well after each addition. Blend in vanilla and heavy cream; pour filling into the cooled baked crust. Gently tap on counter to release air bubbles.
Apple Topping
For the apples, I found it easiest to peel and core them, then slice on a mandoline. Then microwave apples for 60 seconds, then drain any excess liquid (if there is any) and let cool for a few minutes.
In a small bowl, stir together sugar, cinnamon, and flour. Toss the apples gently in mixture to coat. Lay apples on top of cheesecake, slightly overlapping the slices to create a shingled pattern. You should have enough apples to do 3-4 layers deep, then if there is any liquid at the bottom of the bowl, pour evenly over top of the apples.
Streusel Topping
Mix all dry ingredients in a small bowl. Add butter and combine until all ingredients are crumbly (I find this easiest if you add butter and pinch it into the dry ingredients). Spread evenly over the top of the cheesecake.
Bake in preheated oven for 60 to 70 minutes. It will be difficult to see if the cheesecake set due to the apple layer, but give the pan a gentle shake and the middle should have a little give to it. You can also use a thermometer, just insert it into the center of the cheesecake and once it reaches 150°F you are good to remove from the oven. Let cool on a baking rack, then chill cheesecake bars completely before serving.
