Ritz Crakers
1 Pound Semisweet Chocolate
2 Drops Peppermint Extract

that's it these are really tasty and pretty close.
if you want the dark cookie I dont have a recipe but I would suggest using oreo cookie crumbs(available from a retail suplier like Bakemart) in place of flour in a regular recipe for thin wafers cookies. This will give you the color and flavor your looking for.
