01 - Line the base of a 9-inch springform pan with parchment paper and set aside.
02 - Combine the crushed graham crackers with the melted butter in a medium bowl, stirring until the crumbs are evenly moistened. Press the mixture firmly into the bottom of the prepared pan, creating a uniform and compact layer. Place the pan in the refrigerator to chill while you prepare the filling.
03 - Using an electric mixer, beat the softened cream cheese with the powdered sugar and vanilla extract in a large bowl until completely smooth and free of lumps.
04 - Pour in the full-fat coconut milk and continue beating until the mixture is well blended and silky.
05 - Gently fold the chopped pineapple tidbits and desiccated coconut into the cream cheese mixture using a spatula, distributing them evenly throughout.
06 - In a separate chilled bowl, whip the heavy cream until stiff peaks hold their shape. Carefully fold the whipped cream into the pineapple coconut mixture in three additions, maintaining as much volume as possible.
07 - Spread the filling evenly over the chilled crust, smoothing the surface with a spatula to create a level top.
08 - Cover the pan tightly with plastic wrap and refrigerate for a minimum of 4 hours, or ideally overnight, until the filling is firm and fully set.
09 - Before serving, remove the springform ring and decorate the top with toasted coconut flakes and additional pineapple slices or tidbits.
