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 with the melted butter in a medium bowl until the mixture resembles wet sand. Press firmly and evenly into the bottom of the prepared pan. Place in the refrigerator to set while preparing the filling.
03 - In a large mixing bowl, beat the softened cream cheese with the powdered sugar and vanilla extract using an electric mixer until completely smooth and lump-free.
04 - Pour in the full-fat coconut milk and continue beating until the mixture is fully combined and silky in texture.
05 - Gently fold in the drained, chopped pineapple tidbits and desiccated coconut using a rubber spatula, distributing them evenly throughout the mixture.
06 - In a separate chilled bowl, whip the cold heavy cream until stiff peaks hold their shape. Carefully fold the whipped cream into the pineapple coconut mixture in two additions, preserving as much air as possible.
07 - Pour the filling over the chilled crust, spreading it into an even layer. Smooth the top with an offset spatula or the back of a spoon.
08 - Cover the pan tightly with plastic wrap and refrigerate for a minimum of 4 hours, or preferably overnight, until the filling is firm and fully set.
09 - Remove the cake from the refrigerator, release the springform ring, and garnish the top with toasted coconut flakes and fresh pineapple slices or tidbits before slicing.
