Mint cake is a food item that, when eaten, will restore a player's run energy to 100%. Mint cakes restore more energy per consumption than any other item using only one click. Super energy potions (4) can restore up to 160% of a player's run energy at 4 clicks, however, the mint cake is instantaneous.
A mint cake can be obtained as a possible reward from the Gnome Restaurant minigame, as a possible reward from the light creature at the Hefin Agility Course in Prifddinas, and can also be obtained by exchanging Tangled toads' legs with Longramble during or after The Path of Glouphrie quest. This exchange can only be made once.
Before 1 February 2010, mint cakes were very rare and valuable as it was rare to obtain them from the Gnome Restaurant minigame. They were perceived as valuable items, used in junk trades to buy items for a price much higher than that of the Grand Exchange's. However, on 1 February 2010, the chance of getting a mint cake reward from the Gnome Restaurant minigame was increased considerably. Furthermore, they are now received in amounts ranging from 8-10 rather than individually. With the 10 November 2014 update and expansion to the Elven city of Prifddinas, the Hefin Agility Course offers mint cakes as a common reward, leading to their further devaluation.
