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.
