01 - Line the base of a 9-inch springform pan with parchment paper, pressing it flat to ensure an even surface.
02 - Combine the crushed graham crackers and melted butter in a medium bowl until the crumbs are evenly moistened. Press the mixture firmly into the bottom of the prepared pan, creating a uniform, compact layer. Place the pan in the refrigerator to chill while preparing the filling.
03 - Beat the softened cream cheese with powdered sugar and vanilla extract in a large bowl using an electric mixer until completely smooth and free of lumps.
04 - Pour the full-fat coconut milk into the cream cheese mixture and beat until fully combined and silky.
05 - Gently fold in the chopped pineapple tidbits and desiccated coconut using a rubber spatula, distributing them evenly throughout the mixture.
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 two additions, maintaining as much air as possible.
07 - Spread the filling evenly over the chilled crust, smoothing the top with an offset spatula or the back of a spoon.
08 - Cover the pan tightly with plastic wrap and refrigerate for at least 4 hours, or preferably overnight, until the filling is firm and set.
09 - Before serving, remove the springform ring and garnish the top with toasted coconut flakes and additional pineapple slices or tidbits. Slice with a warm knife for clean portions.
