Melt the chocolate in a small deep bowl over a double boiler.
Using a brush, paint the inside of a cone with some chocolate. While it is still wet, sprinkle a little of one or more of the sprinkles, pecans, chocolate candies or pretzels into the cone. Continue with the rest of the cones. Let dry.
Dip the top 2 inches of each cone in the melted chocolate and coat with more of the decorations. Stand the cones in a glass to dry.
To serve, fill the cones with some Triple Mint Choc Chip Ice Cream or your favorite ice cream and top with more of the decorations.
Stir together the ice cream, chocolate chips, white chocolate chips, mint patty candies, creme de menthe candies and mint candies in a large bowl until combined. Transfer to a container, cover and freeze for 4 hours.
