Buttercream Choco Cookie is a B-grade Cookie with the ability to give a coin bonus from 5% up to 25%. It is recommended to level him up very early in the game, as he is one of the best Cookies for Coin Farming. Although his Combi Pet is Dust Unicorn, players tend to use alternative Pets to get more Coins out of runs.
