In a mixing bowl, combine graham cracker crumbs, ¼ cup sugar, and melted butter. Stir until well combined and resembles wet sand.
Press the mixture firmly into the bottom of a 9-inch springform pan to create an even crust. Bake for 10 minutes, then remove from the oven and let it cool.
In a large mixing bowl, beat the cream cheese until smooth and creamy. Gradually add in 1 cup of sugar and vanilla extract, mixing until combined.
Add eggs, one at a time, mixing well after each addition. Incorporate the flour, ground cinnamon, and cream of tartar until fully blended.
Add sour cream and mix until smooth. Pour the cheesecake batter over the cooled crust in the springform pan.
In a small bowl, mix 2 tablespoons of brown sugar with a teaspoon of cinnamon. Sprinkle this mixture over the cheesecake batter.
Bake for 55-60 minutes or until the cheesecake is set and the edges are slightly golden. The center should still have a slight jiggle.
Turn off the oven and leave the cheesecake inside with the door ajar for 1 hour to cool slowly, then refrigerate for at least 4 hours or overnight.
Before serving, you can top with whipped cream and a sprinkle of cinnamon for an extra decadent touch.
Notes
