Step 1: Make That Crust
Preheat your oven to 325°F (160°C). In a medium bowl, mix graham cracker crumbs, sugar, and melted butter until it resembles wet sand. Press the mixture firmly into the bottom of a 9-inch springform pan. Use the bottom of a glass to pack it down evenly. Bake for 10 minutes, then let it cool while you prep the filling.

Step 2: Whip Up the Filling
In a large mixing bowl, beat the cream cheese and sugar together until smooth and fluffy — no lumps allowed. Add the eggs one at a time, mixing just until incorporated after each (don’t overbeat, we’re not making whipped cream here). Stir in sour cream, heavy cream, lemon zest, lemon juice, vanilla, and salt. Scrape down the sides to make sure everything’s silky and combined.

Step 3: Bake It Gently
Pour the filling over the cooled crust. Tap the pan gently on the counter to release any air bubbles (goodbye, cracks!). Place the springform pan inside a larger roasting pan, and pour in hot water halfway up the sides for a water bath. Bake for 55–65 minutes, until the center is just slightly jiggly but the edges are set.

Step 4: Chill Out (Literally)
Turn off the oven, crack the door open, and let the cheesecake cool inside for 1 hour. This helps prevent cracks. Then remove it, run a knife around the edge, and cool completely at room temperature. Chill in the fridge at least 6 hours (overnight is best — patience pays off).

Step 5: Make That Dreamy Lemon Topping
In a small saucepan, whisk together lemon juice, sugar, and egg yolks over medium heat. Stir constantly until thick enough to coat the back of a spoon (about 5–7 minutes). Remove from heat and stir in butter and lemon zest until smooth and glossy. Let it cool slightly, then spread over the chilled cheesecake.

Step 6: Slice and Serve Like a Pro
Refrigerate for at least another hour so the topping sets beautifully. When ready to serve, slice with a hot knife (wipe between cuts for perfect slices). Each piece should have that gorgeous layered look — crust, creamy cheesecake, and a shiny lemon crown.
