Yoshi Cookie

A Yoshi Cookie is a cookie that first appeared in Yoshi's Cookie. It is the favorite snack of the Yoshis.

Tayce T. can make this treat Paper Mario if Mario gives her a Melon and some Cake Mix. It restores 15 HP and 15 FP. The yellow Yoshi in Yoshi's Village has a melon if you bring him any food made with Cake Mix.

In Game & Watch Gallery 4, the modern version of Mario's Cement Factory replaces cement making with cookie making. the cookies are from Yoshi's cookie

In Super Mario RPG Mario and Yoshi were required to bring Yoshi Cookies to Boshi in exchange for a race. Yoshi Cookies also could be used in battle where they would summon Yoshi and he would eat an enemy

In Mario & Luigi: Partners In Time in the level Yoshi's Island, Kamek is getting cookies for Baby Bowser. When Kamek gives them to him, Baby Bowser eats too fast, and he feels sick.

Luigi takes four Yoshi Cookies that Kamek dropped. He gives one to Baby Luigi immediately. Later, he gives two cookies to Baby Mario and Baby Luigi to calm them down after a crash landing in Yoob's Belly. The remaining cookie Luigi gives Baby Luigi at the very end of the game, in exchange for Baby Luigi's Hammer.

A battle course in Mario Kart: Super Circuit and Mario Kart: Double Dash!! is named Cookie Land and has Yoshi Cookies in the background.

The item Sweet Cookie Snack of Super Paper Mario looks a lot like a Yoshi Cookie-so much that they probably are Yoshi Cookies with a different name.
