Step 1: Prepare the Crust

1. Preheat your oven to 325°F (160°C) and line a 12-cup muffin tin with paper liners.
2. In a mixing bowl, combine the graham cracker crumbs, melted butter, granulated sugar, and ground cinnamon. Stir until the mixture has the texture of wet sand.
3. Divide the mixture evenly between the muffin cups, pressing it down firmly with the back of a spoon or a small glass to form a solid crust layer.
4. Bake the crusts for 5 minutes, then set aside to cool while you prepare the cheesecake and pumpkin fillings.

Step 2: Make the Cheesecake Layer

1. In a large mixing bowl, beat the softened cream cheese and granulated sugar together until smooth and creamy, about 2-3 minutes.
2. Add the egg and vanilla extract, mixing until just combined. Be careful not to overmix, as this can lead to air bubbles that might cause cracking.
3. Spoon about 1 tablespoon of the cheesecake mixture into each muffin cup, spreading it evenly over the graham cracker crust.

Step 3: Make the Pumpkin Layer

1. In a separate mixing bowl, whisk together the pumpkin puree, brown sugar, egg, cinnamon, nutmeg, ginger, cloves, and flour until smooth and well combined.
2. Gently spoon the pumpkin mixture over the cheesecake layer in each muffin cup, spreading it to the edges to fully cover the cheesecake layer.

Step 4: Bake and Cool

1. Bake the mini cheesecakes at 325°F (160°C) for 18-20 minutes, or until the centers are set but still slightly jiggly.
2. Turn off the oven, crack the door slightly, and allow the cheesecakes to cool for 10 minutes in the oven to prevent cracking.
3. Remove from the oven and let the cheesecakes cool completely on a wire rack.
4. Once cooled, refrigerate the cheesecakes for at least 3 hours, or until fully chilled and set.

Step 5: Garnish and Serve

1. Before serving, add a dollop of whipped cream on top of each mini cheesecake for an extra touch of sweetness.
2. Garnish with a sprinkle of cinnamon, crushed graham crackers, or even a ginger snap cookie for added flavor and texture.
3. Serve chilled and enjoy these autumnal treats!
