01 - Combine graham cracker crumbs, melted butter, and granulated sugar in a bowl. Mix until evenly moistened and press firmly into the bottom of a 9-inch springform pan. Refrigerate while making the filling.
02 - Beat softened cream cheese in a large bowl until smooth and creamy. Add powdered sugar, vanilla extract, lemon zest, and 2 tablespoons reserved pineapple juice. Beat until fully combined.
03 - Fold in 1 1/2 cups drained crushed pineapple until evenly distributed throughout the cream cheese mixture.
04 - In a separate chilled bowl, whip cold heavy cream until stiff peaks form. Be careful not to over-whip.
05 - Gently fold the whipped cream into the cream cheese mixture until fully incorporated and smooth.
06 - Spread the filling evenly over the chilled crust. Smooth the top with a spatula, cover with plastic wrap, and refrigerate for at least 4 hours or until completely set.
07 - Before serving, top with additional well-drained crushed pineapple. Garnish with whipped cream and fresh mint leaves if desired. Release from springform pan and slice into portions.
