One of the easiest recipes I've ever tried is making these crackers.
1 packet of Ritz crackers (get whatever brand you like. We always use the homebrand)
1 packet melting chocolate
Cotton wool balls
Melt the chocolate and dip the crackers in. Make sure they are coated nicely. Place on wax paper to dry. Now layer them in a sealed container with the wax paper in between. As you layer them place a cotton ball that has got some of the peppermint extract on it (You know what to do, just put the cotton ball on the bottle and up end the bottle...don't soak the ball) in amongst the cookies. Only need about two or three balls per layer. Now seal the container and leave it for two or three days.
When you bite into them they will taste exactly like a mint choc cookie.
