Spread mixture evenly over chilled base. Refrigerate for at least 2 hours.
In cold bowl of stand mixer fitted with whisk attachment, beat the whipping cream starting at low speed and increasing to medium speed until soft peaks start to form. Add the icing sugar, cream of tartar, and vanilla and continue to beat the mixture just until stiff peaks barely form. Do not overbeat. Remove bowl from mixer stand and gently fold in the well-drained crushed pineapple. Spread topping over chilled cheesecake layer and sprinkle reserved ¼ cup of graham wafer mixture over top of dessert. Refrigerate at least 2 hours before serving. Cut into desired-sized pieces.
