Lay the biscuits flat on a chopping board or baking tray.
Spread the vanilla frosting over the top of each cookies with a knife.
Decorate with the red and green M&Ms.
Add a round chocolate to the top of each cookie.
Allow the frosting to set (please note: most frostings will still stay slightly soft).
