- Preheat your oven to 325°F (160°C). Grease a 9-inch springform pan and line the bottom with parchment paper. 
- Crush the graham crackers into fine crumbs and mix with melted butter. Press firmly into the bottom of the pan. Bake for 10 minutes, then set aside to cool. 
- In a large mixing bowl, beat the cream cheese and sugar until smooth and fluffy. Don’t rush—this step sets the tone. 
- Add sour cream, cornstarch, salt, and vanilla. Mix just until combined. 
- Crack in the eggs one at a time, mixing gently after each one. Avoid overmixing—it traps air and cracks the top. 
- Pour the batter over the crust and smooth the top. Give it a tap on the counter to release any sneaky air bubbles. 
- Bake in the center of your oven for 1 hour 20 minutes. Turn off the oven, crack the door, and let it sit inside for another hour. 
- Cool completely at room temperature, then refrigerate for at least 4 hours—overnight is even better. 
- Slice with a hot knife and serve plain or topped with fresh berries, caramel, or whatever makes your cheesecake-loving heart happy.
