  • 1 3.4 ounces package vanilla instant pudding mix
  • 1 cup milk
  • 2 tablespoons key lime juice
  • 1 tablespoon lime zest
  • 16 full Graham Cracker sheets
  • 16 ounces cool whip divided
  • Limes or lime zest for decoration optional


  • Whisk pudding and milk, let sit until mostly set. Whisk in lime juice and zest, then fold in one tub (8 ounces) whipped topping.
  • Line the bottom of an 8” or 9” square pan with graham crackers (break the sheets to fit). Place 1/3 of the pudding mixture on top and evenly spread it out. Top with more graham crackers, more pudding, etc, for 3 layers of pudding and 4 layers of graham crackers. (You will end with graham crackers on top.)
  • Frost the top with more whipped topping. Cover and chill at least 4 hours or overnight. Decorate with lime slices and/or zest if desired. Store loosely covered in the refrigerator.
