Whats the name of this kind of cookie?!

my mom has this friend who is korean.. i think. well she used to make these cookies for me when i was in 8th grade. I thought was called "mookie" or something like that. I just remember it consists of beans i guess sweet beans. the cookies were green and white. the white ones had yellow sweet beans so did the green ones. I dont remember what the outside was made of. I loved thos cookies and still do.. i was just wondering where i could go to purchase cookies like that or what the recipe was? Does anyone know what i am talkin about? if you know any recipes please let me know..
