Method
- Make the crustStir the graham cracker crumbs, brown sugar, and melted butter together in a bowl until every crumb feels damp. Transfer to a 9-inch springform pan and press firmly into the bottom and about one inch up the sides using the flat base of a measuring cup. Pack it hard. A loosely pressed crust crumbles when sliced.
- Chill the crustPlace the pan in the freezer for 10 to 20 minutes while you prepare the filling. A briefly frozen crust holds its shape when the filling goes in and stays intact through the overnight chill.
- Whip the cold heavy creamBeat the cold heavy cream with a mixer on medium-high speed until stiff peaks form, about 4 to 5 minutes. Stop the moment the cream holds a firm, upright peak. Overwhipping turns it grainy and eventually produces butter.
- Beat the cream cheeseIn a separate large bowl, beat the room-temperature cream cheese and granulated sugar on medium speed until completely smooth, about 3 minutes. Cold cream cheese produces lumps that never fully incorporate.
- Add the remaining filling ingredientsAdd the confectioners' sugar, sour cream, lemon juice, and vanilla extract to the cream cheese mixture. Beat on medium-high speed for 2 to 3 minutes until the filling looks completely uniform and smooth.
- Fold in the whipped creamAdd the whipped cream to the cream cheese mixture and fold gently with a silicone spatula using slow, sweeping strokes from the bottom of the bowl upward. Aggressive stirring deflates the whipped cream and produces a dense, heavy filling. Take your time.
- Fill and chillSpread the filling into the frozen crust and smooth the surface with an offset spatula or the back of a spoon. Cover tightly with plastic wrap pressed directly onto the filling surface and refrigerate for at least 6 to 8 hours. Overnight produces a significantly firmer, cleaner-slicing result.
