Cookies are recovery items in EarthBound and Mother 3, being the Cookie in EarthBound and the Nut Cookie (Japanese: このみクッキ-Nut Cookie) in Mother 3. Both items restore a low amount of HP to a party member.
In EarthBound the Cookie restores approximately 6 HP when eaten. Eating it with a Tin of cocoa will double the amount of HP restored.
In Mother 3 the Nut Cookie will restore approximately 15 HP. They are made from Nuts found in the game. In Chapter 1 to Chapter 3 one Nut can be given to Caroline and she will bake it into a Nut Cookie. Mike will also give the player his "slightly unclean and not very tasty" Nut Cookies throughout Chapters 1-3.
