Melt the chocolate wafers over a double boiler. Bring a small pot of water to a boil. Fit a glass or metal bowl snuggly in the top of the pot, making sure the boiling water does not touch the bowl. Place the chocolate in the bowl and stir while the chocolate melts.
Off the heat stir the peppermint extract into the melted chocolate.
One at a time, place the Ritz Crackers into the chocolate. Using a fork turn it around in the chocolate to coat completely.
Remove the cookie from the chocolate by laying it on the fork. Let the excess chocolate drip from the cookie. You can also lightly shake the cookie back and forth, this will also level the chocolate on top.
Place on a parchment lined sheet pan to dry/harden. This will take about 15-30 minutes.
If your chocolate starts to get tacky while you are dipping the crackers place it back on the double boiler for a minute or two until the chocolate is smooth again.
