Making Cranberry Crumble Cheesecake Bars is simple if you follow these clear steps:

1. Preheat Oven: Preheat your oven to 325°F (160°C). Grease a 9×9-inch baking pan or line it with parchment paper for easy removal.
2. Prepare the Crust: In a bowl, combine graham cracker crumbs, granulated sugar, melted butter, and ground cinnamon. Mix until well combined.
3. Press Mixture: Firmly press the crumb mixture into the bottom of the prepared baking pan. Bake for about 10 minutes, then remove from the oven.
4. Prepare Filling: In a large mixing bowl, beat the softened cream cheese and sugar until smooth. Add eggs one at a time, mixing well after each addition. Stir in vanilla extract.
5. Coat Cranberries: In a separate bowl, toss the chopped cranberries with the tablespoon of flour. This helps prevent them from sinking in the filling.
6. Add Cranberries: Gently fold the floured cranberries into the cheesecake mixture until evenly distributed.
7. Pour Filling: Pour the cheesecake filling over the baked crust, smoothing it out with a spatula.
8. Prepare Topping: In another bowl, combine oats, brown sugar, all-purpose flour, salt, and ground cinnamon. Cut in the cold cubed butter until the mixture resembles coarse crumbs.
9. Add Topping: Sprinkle the crumble topping evenly over the cheesecake layer.
10. Bake: Return the pan to the oven and bake for 30-35 minutes, or until the filling is set and the top is lightly browned.
11. Cool: Remove from the oven and allow to cool at room temperature for 2 hours. For best results, refrigerate for an additional hour before cutting into bars.
