01 - Line the base of a 9-inch springform pan with parchment paper, ensuring the paper lies flat against the bottom.
02 - Combine the crushed graham crackers and melted butter in a medium bowl until the mixture resembles wet sand. Press firmly into the base of the prepared pan to form a compact, even layer. Place in the refrigerator to set 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 in the full-fat coconut milk and continue beating until the mixture is well blended and silky.
05 - Fold the chopped pineapple tidbits and desiccated coconut into the cream mixture using a rubber spatula, distributing evenly throughout.
06 - In a separate chilled bowl, whip the cold heavy cream until stiff peaks hold their shape. Gently fold the whipped cream into the pineapple coconut mixture in two additions, preserving as much air volume as possible.
07 - Spread the finished filling evenly over the chilled crust, smoothing the surface with a spatula to create a level top.
08 - Cover tightly with plastic wrap and refrigerate for at least 4 hours or overnight until the filling is fully set and holds its shape when sliced.
09 - Just before serving, arrange toasted coconut flakes and fresh pineapple slices over the top. Slice with a warm knife for clean portions.
