Creating this delightful Pumpkin Streusel Cheesecake is a rewarding experience. Follow these steps to ensure success:

1. Preheat the Oven: Preheat your oven to 325°F (160°C). Grease a 9-inch springform pan.
2. Prepare the Crust: In a bowl, combine graham cracker crumbs, granulated sugar, and melted butter. Mix until well combined. Press the mixture into the bottom of the prepared pan.
3. Make the Cheesecake Filling: In a large mixing bowl, beat the softened cream cheese until smooth. Gradually add the granulated sugar, pumpkin puree, eggs, vanilla extract, cinnamon, nutmeg, ginger, and salt. Mix until fully combined and creamy.
4. Pour the Filling: Pour the cheesecake filling over the prepared crust, smoothing the top with a spatula.
5. Prepare the Streusel Topping: In a separate bowl, combine flour, rolled oats, brown sugar, softened butter, and cinnamon. Mix until crumbly.
6. Add the Streusel: Sprinkle the streusel topping evenly over the cheesecake filling.
7. Bake: Bake in the preheated oven for 50-60 minutes, or until the center is set and the edges are lightly golden.
8. Cool: Once baked, remove the cheesecake from the oven and allow it to cool in the pan for about 10 minutes. Then, release the sides of the springform pan and let it cool completely on a wire rack.
9. Chill: After cooling, refrigerate the cheesecake for at least 1 hour before serving to ensure it sets properly.
