Combine the graham cracker crumbs, granulated sugar, and salt in a medium bowl. Pour in the melted butter and stir until all the crumbs are evenly moistened and the mixture looks like wet sand.

Press the crust mixture firmly and evenly into the bottom and about 1 inch up the sides of a 9-inch springform pan. Use the flat bottom of a measuring cup to pack it down tightly — this is key for clean slices later. Transfer to the refrigerator while you make the filling.

In a large bowl, beat the room-temperature cream cheese with a hand mixer or stand mixer fitted with the paddle attachment on medium-high speed for 2-3 minutes until completely smooth, fluffy, and free of any lumps.

Add the sifted powdered sugar, vanilla extract, lemon juice, and lemon zest. Beat again on medium speed until fully combined and smooth, scraping down the sides of the bowl as needed. Taste and adjust lemon or sweetness to your preference.

In a separate cold bowl, whip the heavy cream and the additional 1/4 cup powdered sugar together on high speed until stiff, glossy peaks form — the cream should hold its shape firmly when the beaters are lifted. This typically takes 3-4 minutes.

Using a large rubber spatula, gently fold the whipped cream into the cream cheese mixture in two additions. Use slow, deliberate folding strokes to maintain as much of the whipped cream's volume as possible. Fold only until no white streaks remain — don't over-mix.

Remove the crust from the refrigerator. Pour the cheesecake filling onto the crust and use an offset spatula or the back of a spoon to spread it into an even, smooth layer.

Tap the pan gently on the counter a few times to release any air bubbles. Smooth the top once more if needed.

Cover the pan loosely with plastic wrap and refrigerate for a minimum of 4 hours, or ideally overnight (6-8 hours) until the filling is completely firm and set.

When ready to serve, run a thin knife or offset spatula around the inside edge of the springform pan before releasing the clasp and removing the sides. Top with fresh sliced strawberries, mixed berries, or your preferred topping. Slice with a sharp knife wiped clean between cuts for the neatest presentation.
