01 - Line the base of a 9-inch springform pan with parchment paper and set aside.
02 - Combine the crushed graham crackers and melted butter in a medium bowl until the mixture resembles wet sand. Press firmly into the bottom of the prepared pan to create an even, compact layer. Place in the refrigerator to chill while preparing the filling.
03 - In a large mixing bowl, beat the softened cream cheese with 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 homogeneous and silky.
05 - Gently fold in the chopped pineapple tidbits and desiccated coconut using a rubber spatula, distributing evenly throughout the mixture.
06 - In a separate chilled bowl, whip the heavy cream until stiff peaks hold their shape. Delicately fold the whipped cream into the pineapple coconut mixture in three additions, preserving as much volume as possible.
07 - Spread the filling evenly over the chilled crust, smoothing the surface 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 - Just before serving, arrange toasted coconut flakes and fresh pineapple slices or tidbits over the top. Slice with a warm knife for clean portions.
