A Gingerbread House is a recipe found in Super Paper Mario and it's made by Dyllis. As its name implies, it looks exactly like a sturdy gingerbread house. It's made from a Chocolate Cake and a Mousse. Using it restores thirty HP and cures poison, twice as much HP as either ingredient on its own, and equal to the healing sum of both (15+15=30)
"Home sweet home. Restores 30 HP and cures poison. Made from a Chocolate Cake and a Mousse."
