  • 1 (11 oz pkg) pecan shortbread cookies (such as Pecan Sandies) coarsely crushed
  • 5 Tbsp butter melted

  • 2/3 cup crushed pineapple well drained
  • 1 (16 oz tub) Cool Whip thawed and divided

  • Lightly grease an 8x8" square pan with cooking spray; set aside. In a large bowl, combine the coarse cookie crumbs and butter until moistened. Press evenly into the prepared pan and set aside.
