Step 1: Prepare the Crust

Preheat your oven to 325°F (163°C). In a mixing bowl, combine 1 and ½ cups of graham cracker crumbs, ¼ cup of sugar, and ½ cup of melted butter. Mix until evenly combined. Press this crust mixture firmly into the bottom of a springform pan and set aside.

Step 2: Make the Cheesecake Filling

In a large mixing bowl, beat 24 oz of softened cream cheese and 1 cup of sugar together until smooth and creamy. Add 1 tbsp of vanilla extract, mixing well before adding 3 large eggs, one at a time. Blend in ¾ cup of sour cream and ¼ cup of all-purpose flour until fully combined. Pour half of this cheesecake mixture over the prepared crust.

Step 3: Create the Cinnamon Swirl

In a separate small bowl, combine ½ cup of brown sugar, 2 tbsp of ground cinnamon, and ¼ cup of melted butter. Mix together until well incorporated. Dot half of this cinnamon mixture over the cheesecake layer, then use a knife to gently swirl it into the batter to create a cinnamon roll pattern.

Step 4: Combine Layers

Pour the remaining cheesecake batter over the cinnamon-swirl layer. Repeat the swirling process with the rest of the cinnamon mixture on top, creating an even more delightful pattern.

Step 5: Bake the Cheesecake

Place the springform pan in the preheated oven and bake for 50-55 minutes, or until the center is set but still slightly jiggly. Once done, allow the cheesecake to cool for a short time. After cooling, refrigerate for at least 4 hours or overnight before serving.
