Couple's Cake is a recipe that can be made by Zess T. or Dyllis. It works just like a Slow Shroom, except it only affects Mario's Partner. In Paper Mario: The Thousand-Year Door, Mario receives a Couple's Cake for completing the trouble titled "Looking for a gal". It can also be made by cooking a Snow Bunny and either a Berry Snow Bunny or Spicy Soup. According to Rogueport Sewers resident Wonky, Couple's Cakes remind Zess T. of her late husband, so she is hesitant about making them. This is a coincidence to Tayce T.'s story about Cake; she won her now deceased husband over it.
