Lemon Cheesecake with Glaze

For the crust:
Preheat your oven to 325°F (163°C).
In a medium bowl, combine the graham cracker crumbs, sugar, cinnamon (if using), and melted butter. Stir until the mixture is evenly combined and resembles wet sand.
Press the mixture into the bottom of a 9-inch springform pan, ensuring an even layer. Bake for 8–10 minutes, until lightly golden. Remove from the oven and let it cool completely.
For the cheesecake filling:
Lower the oven temperature to 300°F (150°C).
In a large mixing bowl, beat the softened cream cheese and sugar together until smooth and creamy, using a hand mixer or stand mixer on medium speed.
Add the vanilla extract, eggs (one at a time), sour cream, and heavy cream. Beat until smooth, scraping down the sides as necessary.
