1/2 cup unsalted butter, 4 oz cream cheese, 2 cups powdered sugar
Fold the remaining drained pineapple into the Cool Whip and spread on top of the cream cheese mixture. Sprinkle the remaining 1/2 cup of the graham cracker crumb mixture on top. Refrigerate for at least 4 hours, preferably overnight.
